WEBVTT 00:00.000 --> 00:08.800 So yes, so I present myself and Pierre Romant. 00:08.800 --> 00:13.000 I'm here for the first time to first them, so I'm really happy to share our work in the lab. 00:13.000 --> 00:15.000 I'm working in a lab. 00:15.000 --> 00:17.000 It's a mixed unit research. 00:17.000 --> 00:20.000 The name is Umra, it's about environmental acoustics. 00:20.000 --> 00:24.000 And it's mixed unit research, because we are between two institutes. 00:24.000 --> 00:26.000 University of Tel Aviv, and Serema. 00:26.000 --> 00:29.000 It presents you specifically one tool, which is noise milling, 00:29.000 --> 00:33.000 because I am the main facilitator of the tool and one of the main developer. 00:33.000 --> 00:37.000 But I also want to speak more generally about a pencil since the lab is a team, 00:37.000 --> 00:43.000 and also about all the ecosystem around this noise milling tool. 00:43.000 --> 00:48.000 So I know that acoustics, especially on the Romantan noise, is quite a niche subject, 00:48.000 --> 00:52.000 so I have two or three slides to speak about just on the Romantan noise, of course. 00:52.000 --> 00:56.000 So why are you now made in Europe? 00:56.000 --> 01:04.000 We consider that 20% of the people living in our area where noise levels are considered harmful to else, 01:04.000 --> 01:08.000 if we take the threshold of the world else organization. 01:08.000 --> 01:15.000 It's more or less 20 million of people declaring that they have high annoyance. 01:15.000 --> 01:20.000 The sleep disturbance is really high with 6 million people, 01:20.000 --> 01:26.000 that probably have sleep disturbance considering our models. 01:26.000 --> 01:32.000 And there is also directly increase air disease, for example, because it generates stress, 01:32.000 --> 01:36.000 problem when you sleep, and it generates air disease. 01:36.000 --> 01:42.000 It's more or less 50,000 air disease in Europe, directly linked to noise, 01:42.000 --> 01:46.000 and premature mortality and cognitive impairment in children. 01:46.000 --> 01:50.000 So this is as issue is now really well known, 01:50.000 --> 01:56.000 but also in the late 80s, the Fannerachet Kaplan popularized, 01:56.000 --> 01:59.000 the concept of attention restoration theory. 01:59.000 --> 02:03.000 Basically, they say that spending time in natural environment 02:03.000 --> 02:05.000 helps to restore depleted cognitive resources, 02:05.000 --> 02:09.000 and natural environment are not just silent places, 02:09.000 --> 02:15.000 it's also where natural science gap are important, and should be preserved. 02:15.000 --> 02:21.000 A last way to see the problem is noise is not only harmful for humans, 02:21.000 --> 02:22.000 but also for nature. 02:22.000 --> 02:26.000 It can make it harder for animal to communicate, find food, survive. 02:26.000 --> 02:30.000 So it's now really clear evidence that some births, for example, 02:30.000 --> 02:33.000 for the same species, if they live in the rural area, 02:33.000 --> 02:37.000 or if they live in the urban areas, they change the way to sing. 02:37.000 --> 02:43.000 They will sing maybe higher to go over the infrequency to have higher pitch 02:43.000 --> 02:47.000 and to go over the noise or traffic, or they sing louder, 02:47.000 --> 02:51.000 or they sing sooner before the traffic peak at the morning, 02:51.000 --> 02:53.000 or more frequently. 02:53.000 --> 02:56.000 So this is clear evidence for some species, 02:56.000 --> 03:00.000 and we have the same for a lot of different animals. 03:00.000 --> 03:05.000 So this was general idea about environmental noise issues, 03:06.000 --> 03:11.000 and of course, as researchers, we need tools and data to study this, 03:11.000 --> 03:17.000 and we need open tools and open data, because I mean, first of them, you know why. 03:17.000 --> 03:20.000 Okay. 03:20.000 --> 03:28.000 So in the lab, in the lab, we decide to take this a problem with the platform, 03:28.000 --> 03:31.000 now we call it a platform, which is a nice platform. 03:31.000 --> 03:35.000 It begins between a collaboration between two labs, one geometric lab, 03:35.000 --> 03:39.000 GIS expert, lab stick, and all our lab lab art acoustic, 03:39.000 --> 03:42.000 and one of the art acoustics, basically the idea to propose new tools, 03:42.000 --> 03:45.000 based on science features for environmental noise assessment. 03:45.000 --> 03:50.000 The idea behind was, public money, equal, public code, as we can see here, 03:50.000 --> 03:54.000 a lot in the first name, open science. 03:54.000 --> 03:57.000 And of course, black boxes, private software, 03:57.000 --> 04:01.000 to prevent efficient transparent property spill research. 04:01.000 --> 04:03.000 It begins in 2008. 04:03.000 --> 04:10.000 It was the first, the first funder of the platform, the idea I will say, 04:10.000 --> 04:15.000 and the two main guys, what is critical, because the acquisition director of the lab now, 04:15.000 --> 04:19.000 and one bushy on the right side, that was really forced, and still, 04:19.000 --> 04:20.000 really forced on to just. 04:20.000 --> 04:24.000 I say it was because he went a little bit away from the team, 04:24.000 --> 04:28.000 we'll come back about this, because he focused on climate change studies, 04:28.000 --> 04:30.000 but still really close to us. 04:30.000 --> 04:35.000 And they began to work together with this tool. 04:35.000 --> 04:39.000 We now have three tools, noise money, which is a software to do noise maps, 04:39.000 --> 04:43.000 noise capture, which is an Android application to do code sourcing, 04:43.000 --> 04:45.000 mobile measurements. 04:45.000 --> 04:48.000 And the last one now, it's only sensor, which is sensors, 04:48.000 --> 04:52.000 like fixed sensors, that you can put with hardware, 04:52.000 --> 04:56.000 hardware and the software part of the sensor. 04:56.000 --> 05:00.000 Basically, the organization of the noise planet, 05:00.000 --> 05:02.000 seeing I call it platform, because website, 05:02.000 --> 05:05.000 but it's a bit more than that. 05:05.000 --> 05:08.000 There is like official organization, which is inspired by 05:08.000 --> 05:11.000 foundation structure, because we had a foundation in certain universities, 05:11.000 --> 05:15.000 the idea is to have a chair inside and so on. 05:15.000 --> 05:18.000 But this foundation idea is a little bit in standby. 05:18.000 --> 05:23.000 The tools, when, finally, separately, they have separate funding, 05:23.000 --> 05:26.000 separate research projects and so on. 05:26.000 --> 05:30.000 But the devs are shared across a project, because inside the lab, 05:30.000 --> 05:32.000 we have two devs. 05:32.000 --> 05:34.000 The lab is more or less 50 people. 05:34.000 --> 05:39.000 And research and software engineer can work on one tool on the other one, 05:39.000 --> 05:40.000 independently. 05:40.000 --> 05:43.000 So now, we'll do a short focus on noise capture, 05:43.000 --> 05:47.000 which is one of these two main tools. 05:48.000 --> 05:51.000 So noise capture began in 2017, more or less. 05:51.000 --> 05:53.000 It's Android applications. 05:53.000 --> 05:57.000 The idea at the beginning was to dedicate this application for the expert. 05:57.000 --> 06:01.000 And why we did it is because in 2015, more or less, 06:01.000 --> 06:05.000 we began to see a lot of application to measure noise on the store. 06:05.000 --> 06:06.000 Android store. 06:06.000 --> 06:09.000 As a Christian, we were looking at the application on most of them, 06:09.000 --> 06:12.000 was really bad. 06:12.000 --> 06:18.000 I would say, they were not following the thumbnails in acoustics and so on. 06:18.000 --> 06:21.000 So we said, OK, we will do an application, 06:21.000 --> 06:23.000 following the thumbnails of measurements. 06:23.000 --> 06:25.000 We know that they're not going to be bad, 06:25.000 --> 06:32.000 because smartphone, I'm not calibrated outside of the industry. 06:32.000 --> 06:35.000 But still, we wanted to see what we'll happen with this. 06:35.000 --> 06:39.000 And I'll surprise that not only experts began to use the tool, 06:39.000 --> 06:42.000 but it was really used like code source platform, 06:42.000 --> 06:44.000 and a lot of people began to use it. 06:44.000 --> 06:48.000 We have now of more than 300,000 downloads, 06:48.000 --> 06:52.000 and a lot of trace and measurements around the world, 06:52.000 --> 06:54.000 what you can see here. 06:54.000 --> 06:58.000 And here it's the city in the world where we have more measurements, 06:58.000 --> 07:00.000 which is young in France, 07:00.000 --> 07:05.000 because we have really fanatic users in this place. 07:05.000 --> 07:09.000 And we begin to have like really nice maps. 07:09.000 --> 07:12.000 I saw that live demo was appreciated here, 07:12.000 --> 07:14.000 so I will just show you the platform. 07:14.000 --> 07:19.000 So this is the platform where you can see here's the last measurements 07:19.000 --> 07:23.000 that we have done today, for example, in Germany, 07:23.000 --> 07:26.000 oh, your little boy, and so on. 07:26.000 --> 07:29.000 And you can see here's the map past here. 07:29.000 --> 07:33.000 I saw sometimes that quiz was also appreciated here, 07:33.000 --> 07:37.000 so maybe you can try to find, what is this? 07:37.000 --> 07:40.000 Oh, on my screen is okay, but okay. 07:40.000 --> 07:44.000 What is this small, round, really silent area? 07:44.000 --> 07:46.000 Do you have any idea in the city? 07:46.000 --> 07:48.000 No. 07:48.000 --> 07:51.000 Yes, it's a cemetery here. 07:51.000 --> 07:56.000 So this is a silent place in this city. 07:56.000 --> 07:59.000 So that air, I really rough. 07:59.000 --> 08:01.000 They are not calibrated and so on. 08:01.000 --> 08:03.000 It's aggregated on the map. 08:03.000 --> 08:05.000 So we come do a lot just looking about it, 08:05.000 --> 08:07.000 but this is a topic of research for us. 08:07.000 --> 08:10.000 Some PhD has working out to have better quality 08:10.000 --> 08:14.000 that are out to qualify these data and so on and so on. 08:14.000 --> 08:18.000 The tool is not just like short source information. 08:18.000 --> 08:20.000 It's also raising an awareness about noise. 08:20.000 --> 08:21.000 We do some stuff. 08:21.000 --> 08:23.000 The name is noise capture parties. 08:23.000 --> 08:26.000 For example, you have a science festival, something like that. 08:26.000 --> 08:30.000 And you do a noise capture party just behind the side of this. 08:30.000 --> 08:33.000 In university also, this is Italian university. 08:33.000 --> 08:37.000 Each chair, they do a big noise capture party in the university. 08:37.000 --> 08:40.000 So this is the way to use the app. 08:40.000 --> 08:43.000 And lastly, the three or four last year, 08:43.000 --> 08:46.000 we had a project, the name was Sonorose. 08:46.000 --> 08:51.000 And the idea was not to use the app only just to measure 11 and put it in the platform 08:51.000 --> 08:53.000 but to go beyond. 08:53.000 --> 08:55.000 To go beyond. 08:55.000 --> 08:59.000 For example, to see if using the tool as a mediator for the city 08:59.000 --> 09:03.000 then can help them to empower themselves to speak about noise 09:03.000 --> 09:08.000 at the same levels that researchers and elected people. 09:08.000 --> 09:12.000 So we are all in the same room as 25 people, 09:12.000 --> 09:16.000 two of three researchers and two of three elected people. 09:16.000 --> 09:20.000 And the idea was to speak specifically about the airport close to the city 09:20.000 --> 09:24.000 and how we could find solution to raise awareness 09:24.000 --> 09:29.000 or to mitigate some, some, some, some singing and so on. 09:29.000 --> 09:33.000 So it's to explain that maybe it's a really technical tool at the beginning 09:33.000 --> 09:39.000 but the use of the tool is just not around the code 09:39.000 --> 09:41.000 and around the, it's more than that. 09:41.000 --> 09:46.000 It can be useful for research, social, social, and humanities, 09:46.000 --> 09:47.000 and social humanities. 09:47.000 --> 09:50.000 Now we are working in the next chapter two. 09:51.000 --> 09:55.000 So this is the next version of NOS Capture. 09:55.000 --> 09:59.000 I will try to keep it like this. 09:59.000 --> 10:03.000 It's already, it's already online. 10:03.000 --> 10:06.000 You can open to do some measurements. 10:06.000 --> 10:08.000 You have the spectrogram. 10:08.000 --> 10:10.000 And so on. 10:10.000 --> 10:13.000 So if you want to see it, this is on the GitHub platform 10:13.000 --> 10:15.000 so you have to search it a little bit. 10:15.000 --> 10:17.000 But the Android application NOS Capture, 10:17.000 --> 10:20.000 you can download it on the Android store really fast. 10:20.000 --> 10:23.000 I guess it will be releasing during the year, 10:23.000 --> 10:26.000 but we are not totally sure. 10:26.000 --> 10:30.000 And then you have a noise modeling. 10:30.000 --> 10:32.000 So I will try to go fast, 10:32.000 --> 10:35.000 but to speak a little bit about noise modeling. 10:35.000 --> 10:38.000 So the idea is to do noise map for a road range industry 10:38.000 --> 10:42.000 or noise sources at local and national scale. 10:42.000 --> 10:44.000 We implement a method, the name of the method, 10:44.000 --> 10:46.000 this Knossos EU method. 10:46.000 --> 10:49.000 In fact, it's a standard that all European cities 10:49.000 --> 10:52.000 of more than 100,000 inhabitants in Europe 10:52.000 --> 10:54.000 and last transport, in fact, you have a noise map. 10:54.000 --> 10:56.000 If you look inside your country, if you are European, 10:56.000 --> 10:59.000 you are looking inside your country, 10:59.000 --> 11:02.000 that the base, you should find these noise maps. 11:02.000 --> 11:05.000 It takes some inputs like buildings and roads, 11:05.000 --> 11:09.000 all what you can find in open street map, for example. 11:09.000 --> 11:13.000 And thanks to the information about the flow rate of the vehicle 11:13.000 --> 11:15.000 and the percentage of EV and live vehicle, 11:15.000 --> 11:17.000 and seeing like that in the speed, 11:17.000 --> 11:20.000 then we can have a noise emission level, 11:20.000 --> 11:22.000 and we have a pass finder algorithm, 11:22.000 --> 11:25.000 that finds the shortest pass between the source and the receiver, 11:25.000 --> 11:26.000 considering the building, 11:26.000 --> 11:29.000 then we apply some basic physical laws 11:29.000 --> 11:32.000 to have what is a sound level at the receiver place. 11:32.000 --> 11:35.000 And finally, have these nice noise maps. 11:35.000 --> 11:38.000 We began this tool in 2010 already, 11:38.000 --> 11:40.000 it's Java library with the same problems 11:40.000 --> 11:44.000 that the Sinky was calling on this moment was popular 11:44.000 --> 11:47.000 and our Python is much better, but yes. 11:47.000 --> 11:50.000 We are stick with Java and Groovy. 11:50.000 --> 11:54.000 We have connection with Portuguese and H2G databases, 11:54.000 --> 11:57.000 and it's GitHub distributed, you can see here's a GitHub pages. 11:57.000 --> 12:00.000 We have a graphical user interface, which is really ugly, 12:00.000 --> 12:03.000 but sufficient to work with students, 12:03.000 --> 12:06.000 but most of advanced users, of course, use scripts 12:06.000 --> 12:08.000 and stuff like that, much faster. 12:08.000 --> 12:10.000 Website, of course, documentation. 12:10.000 --> 12:13.000 We also use did the publication, the JOS, 12:13.000 --> 12:16.000 which is on the review, but yeah. 12:16.000 --> 12:19.000 I hope it will be okay. 12:19.000 --> 12:23.000 Because we did the update publication about the tool. 12:23.000 --> 12:26.000 And why research needed it, because at this moment, 12:26.000 --> 12:28.000 because it's mandatory in Europe, 12:28.000 --> 12:30.000 a lot of private company began to do their tools, 12:30.000 --> 12:31.000 it's a software. 12:31.000 --> 12:34.000 But for us as research, we could improve, 12:34.000 --> 12:37.000 it was not possible to improve a little bit the acoustic model, 12:37.000 --> 12:39.000 to do some specific chain and so on. 12:39.000 --> 12:41.000 So I will show you just two of us, for example. 12:41.000 --> 12:43.000 This one is a huge chain. 12:43.000 --> 12:46.000 On the left part, a POS seems to me very much 12:46.000 --> 12:48.000 and it's transportation and adjorn based model. 12:48.000 --> 12:50.000 Basically, if you know the game, 12:50.000 --> 12:52.000 it seems to be a city skyline, 12:52.000 --> 12:54.000 it seems to be this kind of thing, 12:54.000 --> 12:56.000 but with real data behind. 12:56.000 --> 13:00.000 And then we can connect this with air pollution 13:00.000 --> 13:03.000 on noise pollution model as noise modelling. 13:03.000 --> 13:06.000 To finally know every 15 minutes, 13:06.000 --> 13:08.000 where are the people in the city, 13:08.000 --> 13:09.000 and which air pollution, 13:09.000 --> 13:12.000 which noise pollution they receive in this place. 13:12.000 --> 13:14.000 So we can follow someone in the city 13:14.000 --> 13:18.000 and to know where are the critical area 13:18.000 --> 13:22.000 in terms of both in population and noise level. 13:22.000 --> 13:27.000 Also, we did some thing about tsunami warning system. 13:27.000 --> 13:29.000 We have a nylon and on this island, 13:29.000 --> 13:31.000 you want to find the best localization 13:31.000 --> 13:35.000 or deterioration or deterioration of siren, if you have a tsunami. 13:35.000 --> 13:37.000 So basically, it's a genetic algorithm. 13:37.000 --> 13:42.000 It gives all these kind of possibilities of configuration of sirens. 13:42.000 --> 13:45.000 So of course, it's not like to replace the Xperpsiren location, 13:45.000 --> 13:48.000 which is black dots, was the idea of the Xperps. 13:48.000 --> 13:50.000 But to propose some other possibilities, 13:50.000 --> 13:52.000 that maybe it can open their mind and say, 13:52.000 --> 13:54.000 okay, maybe this location was a good idea. 13:54.000 --> 13:56.000 And so on. 13:56.000 --> 13:58.000 Also, in our team, 13:58.000 --> 14:01.000 we are really close to the French government for historical reason. 14:01.000 --> 14:03.000 And because we, 14:03.000 --> 14:05.000 friends asked to do noise morphology and fracture, 14:05.000 --> 14:08.000 we began to build a full infrastructure 14:08.000 --> 14:11.000 compute automatically all the noise maps in friends. 14:11.000 --> 14:15.000 So this is the noise map we did in 2022, 14:15.000 --> 14:19.000 and now we are doing the one for 2021. 14:19.000 --> 14:21.000 And you will see after it's important for us, 14:21.000 --> 14:23.000 because part of the found, 14:23.000 --> 14:24.000 we have found noise, 14:24.000 --> 14:26.000 directly come from this. 14:26.000 --> 14:27.000 The, 14:27.000 --> 14:30.000 the, the, the money that saved the French government 14:30.000 --> 14:33.000 because they, they save because they are using us, 14:33.000 --> 14:36.000 we have a little bit a little part of this money 14:36.000 --> 14:37.000 directly like, 14:37.000 --> 14:39.000 from the, the tool. 14:39.000 --> 14:40.000 So there is also users. 14:40.000 --> 14:43.000 Mostly we, we are amends the universities 14:43.000 --> 14:46.000 because these people that need less support 14:46.000 --> 14:48.000 that classical users and we don't, 14:48.000 --> 14:51.000 we are not enough to, to provide support. 14:51.000 --> 14:54.120 But we are a pin-out because, basically, 14:54.120 --> 14:57.840 acquisitions in universities, I know about the tools. 14:57.840 --> 14:59.640 But also some private company are using it. 14:59.640 --> 15:00.880 Some people can teach it. 15:00.880 --> 15:02.560 And we have now a kudji's plugin, 15:02.560 --> 15:05.320 because a Japanese researcher, this is plugin. 15:05.320 --> 15:08.760 It's not perfect, but it's it's working. 15:08.760 --> 15:11.120 We do every year's a nice morning day, 15:11.120 --> 15:13.120 which is one of two days. 15:13.120 --> 15:17.680 Ebrid online offline, depends of the year. 15:17.680 --> 15:22.800 Speaking just about the noise modelling advances 15:22.800 --> 15:27.440 and what's a user have doing with the tool, basically. 15:27.440 --> 15:29.680 And this is organization now. 15:29.680 --> 15:31.840 We have this noise modelling day one time a year. 15:31.840 --> 15:34.080 And the most important level of the organization 15:34.080 --> 15:37.840 is a technical community plus. 15:37.840 --> 15:39.280 Because noise modelling layer is more 15:39.280 --> 15:42.400 less 100 people coming here. 15:42.400 --> 15:45.200 And the technical community is a 20 people more active 15:45.200 --> 15:46.680 on the platform. 15:46.680 --> 15:50.560 Most of them are user, more than the developer, but active. 15:50.560 --> 15:53.200 And it's where it's every three months 15:53.200 --> 15:55.400 and it's where strategic decision are done, 15:55.400 --> 16:00.640 are taken, what will be our next implementation and so on. 16:00.640 --> 16:01.960 Then we have a technical community. 16:01.960 --> 16:03.560 It's only six people. 16:03.560 --> 16:06.840 And it's just like to take really sometimes 16:06.840 --> 16:09.760 we have some strategic decision to take really fast 16:09.760 --> 16:13.960 and we just join all of six people together. 16:13.960 --> 16:15.960 And we should have a nice plan as to your community, 16:15.960 --> 16:19.040 but it never happened. 16:19.040 --> 16:21.680 We communicate inside with formatimen matter, 16:21.680 --> 16:26.520 most kind of slack and alternative. 16:26.520 --> 16:29.560 The phone links come from the lab when the developer 16:29.560 --> 16:31.920 have time because they are not on reset project. 16:31.920 --> 16:36.120 They develop noise capture on the developer noise modelling. 16:36.120 --> 16:42.000 Most of the phone links are from research project, of course. 16:42.000 --> 16:45.200 Especially now, we try for all the people 16:45.200 --> 16:47.080 from the university contacting me because they want 16:47.080 --> 16:49.320 to use noise modelling for the research project. 16:49.320 --> 16:51.920 I asked them to put the funding, of course, 16:51.920 --> 16:57.000 of the size of the project, but to a like 1, 2,000, 3,000 euros 16:57.000 --> 17:01.680 inside the lines saying, OK, I will contribute to the model. 17:01.680 --> 17:04.680 I will contribute to the project with this money. 17:04.680 --> 17:07.680 Basically, help us to do the noise modelling days, for example. 17:07.680 --> 17:08.480 This kind of thing. 17:08.480 --> 17:10.120 Or for example, I am here normally, 17:10.120 --> 17:12.840 I should be here for for them with this kind of money. 17:12.840 --> 17:16.960 It's not the case for other reasons, but here. 17:16.960 --> 17:18.880 So this is the idea. 17:18.880 --> 17:23.720 And it's not enough to have a developer on the tool, 17:23.720 --> 17:28.400 but it's enough to make the tool alive. 17:28.400 --> 17:30.600 We have this amount of money every five years, 17:30.600 --> 17:31.480 because it's mandatory. 17:31.480 --> 17:34.120 So every five years, government should do the noise modelling, 17:34.120 --> 17:35.360 they contact us. 17:35.360 --> 17:39.600 And we say, ah, we need two years of research in the near or 17:39.600 --> 17:43.840 two engineer, as they found these two years of two engineer. 17:43.840 --> 17:46.240 And sometimes we are funding from private company, 17:46.240 --> 17:49.680 but it's really small, because it's only if research is involved. 17:49.680 --> 17:53.840 And yeah, private company don't invest so much in researching 17:53.840 --> 17:57.520 and very modern noise and so on. 17:57.520 --> 18:01.560 I want to take this last minute to speak about two very close projects. 18:01.560 --> 18:05.440 And these two projects are related by Air 1, 18:05.440 --> 18:08.720 Bocher, as the first on Tuesday, I'll show you at the beginning. 18:08.720 --> 18:11.680 One is H2G, this is a spatial database that we are using. 18:11.680 --> 18:14.960 We are not using POSG, it's connected to POSG, 18:14.960 --> 18:18.480 but most of the time we are using this database. 18:18.480 --> 18:22.000 It's much less popular, but it's really useful for us, 18:22.000 --> 18:23.800 especially because it's standalone. 18:23.800 --> 18:29.240 So it's really easy to give your database to someone just a file. 18:29.240 --> 18:35.760 And most of the time, it's most easy to install a POSG server on the side. 18:35.760 --> 18:38.880 Another platform is geoclimate. 18:38.880 --> 18:42.160 It's a geospatial processing tool box. 18:42.160 --> 18:47.040 And Air 1 did the job to finish. 18:47.040 --> 18:50.320 Do you just don't open three-platform data? 18:50.320 --> 18:53.360 And they are directly formatted for noise modeling 18:53.360 --> 18:54.480 to do noise mapping. 18:54.480 --> 18:57.040 So this is a useful tool for us. 18:57.040 --> 18:59.440 We could do it by N or to have our own script, 18:59.440 --> 19:03.120 but it's directly integrated inside this platform. 19:03.120 --> 19:05.680 I see that there is not the link, but of course, 19:05.680 --> 19:07.680 if you put it in Google, you will update it 19:07.680 --> 19:09.840 with the GitHub leak documentation. 19:12.560 --> 19:17.200 So my conclusion, maybe it's just why I'm in for them. 19:17.200 --> 19:20.560 Of course, to get inspired, to get some advice, 19:20.560 --> 19:22.240 reconnect with first community, because there 19:22.240 --> 19:26.880 are one is not so close than before. 19:26.880 --> 19:31.200 I think we have to reconnect a little bit with this community. 19:31.200 --> 19:34.400 To see, of course, as you are, I guess, 19:34.400 --> 19:36.560 to see how other research software 19:36.560 --> 19:39.200 struggle with open source from the X-M antennas, 19:39.200 --> 19:41.040 community and so on. 19:41.040 --> 19:45.040 And also, from two or three years ago, one colleague 19:45.040 --> 19:50.320 won a European project about open research and open source in acoustics. 19:50.320 --> 19:52.800 So you begin to see in the acoustics 19:52.800 --> 19:55.360 Congress some session about open source. 19:55.360 --> 19:58.560 So there is a rise of an acoustic open source community, 19:58.560 --> 20:00.800 much more than before, but it's not clear 20:00.800 --> 20:02.960 or if we have to stay between acousticians, 20:02.960 --> 20:04.880 or if we have to under enforce them and force 20:04.880 --> 20:06.480 for the instead of like this. 20:06.480 --> 20:11.360 So this is this discussion we have inside the group. 20:11.360 --> 20:15.120 And maybe find some logics or a mongubert. 20:15.120 --> 20:16.400 Yes. 20:16.400 --> 20:17.600 So thank you very much. 20:17.600 --> 20:25.600 Thank you. 20:25.600 --> 20:26.800 Yeah. 20:26.800 --> 20:28.080 Yeah. 20:28.080 --> 20:32.160 Have you considered maybe a correlate in open device 20:32.160 --> 20:38.880 and the project more than, like, I think this can have an impact on 20:38.880 --> 20:43.040 how the population is going to be displaced, 20:43.040 --> 20:46.800 because it's been noise and it might be getting working with 20:46.800 --> 20:51.520 a company that will develop building through physicians 20:51.520 --> 20:54.560 and more to place them more to the mutual way that, 20:54.560 --> 20:56.240 you know, there's been noise that will be going to be 20:56.240 --> 20:57.520 over something like that. 20:57.520 --> 20:58.000 Yeah. 20:58.000 --> 21:03.920 So question is, are we connecting the data that we have with 21:03.920 --> 21:09.040 with something as like buildings or like, 21:09.040 --> 21:11.680 how it's moving inside the city and so on? 21:11.680 --> 21:15.360 And the noise capture data is not is really rough. 21:15.360 --> 21:16.880 It's not a good quality data. 21:16.880 --> 21:19.040 So up data. 21:19.040 --> 21:22.480 So I will never did it and I guess it will not work, 21:22.480 --> 21:26.720 because it's spare data and with really different quality and so on. 21:26.720 --> 21:30.640 Now noise modelling, one of the private company I list 21:30.640 --> 21:33.680 is was because it doesn't exist anymore, 21:33.680 --> 21:36.720 but it was a startup providing a website 21:36.720 --> 21:41.840 where I want to, when you want to buy our someone, 21:41.840 --> 21:44.640 it was competing a noise map, a small noise map giving a noise 21:44.640 --> 21:48.240 to develop the facade and you kind of have some information about it. 21:48.240 --> 21:50.000 Yeah, the startup doesn't exist anymore. 21:50.000 --> 21:53.200 I don't know if because the market is not here, 21:53.200 --> 21:56.160 or for other reasons, but yeah, some people are using it. 21:56.160 --> 21:59.840 But yeah. 21:59.840 --> 22:02.480 But I saw only three research tropics here, 22:02.480 --> 22:04.720 but of course we are connected with epidemiologists. 22:04.720 --> 22:08.400 For example, we are connected with people in 22:08.400 --> 22:11.840 ecological science, biodiversity and so on. 22:11.840 --> 22:17.120 We also have simulation to see how the noise level actually 22:17.120 --> 22:20.480 all over the time. 22:20.480 --> 22:22.960 This is something, a topically interesting, 22:22.960 --> 22:24.960 but we have two issues. 22:24.960 --> 22:28.160 Oh, again, noise capture data is not a good quality. 22:28.160 --> 22:30.640 And noise modelling, as a single model 22:30.640 --> 22:33.680 are going really, are changing also time. 22:33.680 --> 22:37.760 So it's really difficult to be sure that the change in noise level 22:37.760 --> 22:41.760 is not due to the change of the model of the quality of the input data. 22:41.760 --> 22:44.560 Or if it's due to a modification of mobility, 22:44.560 --> 22:47.040 for example, transportation and so on. 22:47.040 --> 22:51.520 And for example, for the moment, the studies that we are done 22:51.520 --> 22:54.240 are, for me, it's not really clear what we are looking at. 22:54.240 --> 22:56.560 If we are looking at change of method or yeah. 22:56.560 --> 22:59.520 But I guess one time we will have a really nice paper 22:59.520 --> 23:03.440 doing it well, but not at the moment. 23:03.440 --> 23:04.240 Yeah. 23:04.240 --> 23:06.960 My question is very similar, but I don't know about that. 23:06.960 --> 23:10.000 And so it's a couple of minutes, and it's very flexible. 23:10.000 --> 23:13.040 I think when populations like those, 23:13.040 --> 23:16.800 some of them are going to be able for normal life, 23:16.800 --> 23:18.960 take advantage like that, and maybe use them 23:18.960 --> 23:21.280 or handle them as possible. 23:21.280 --> 23:24.880 Yeah, the question is if there is like big festival in the city, 23:24.880 --> 23:27.760 the population can double, and oh, we could handle 23:27.760 --> 23:31.200 this kind of phenomenon in the platform. 23:31.200 --> 23:33.840 And noxmoling is perfectly adaptive to this kind of thing, yeah. 23:33.840 --> 23:37.520 And the model, you can simulate the doubling traffic 23:37.520 --> 23:38.960 in the city and so on. 23:38.960 --> 23:42.240 The main issue when you do this kind of thing is, 23:42.240 --> 23:46.080 if you don't that transportation model connected, 23:46.080 --> 23:49.200 you can double the traffic, but maybe traffic can't go, 23:49.200 --> 23:51.440 you have congestion, and so on, and this kind of thing, 23:51.440 --> 23:55.680 or traffic will change the routes that they will take. 23:55.680 --> 23:57.840 So people will change the routes they will take. 23:57.840 --> 24:02.880 So it's exactly why we are working with this kind of big chain of model 24:02.880 --> 24:06.160 to connect to this traffic model, because it's like one piston or more. 24:06.160 --> 24:10.000 So for example, that's not much traffic increases. 24:10.000 --> 24:11.120 Other than the human traffic. 24:11.120 --> 24:12.320 Ah, yes, perfect. 24:12.320 --> 24:13.360 What do we call it? 24:13.360 --> 24:16.160 At the end of the day, we'll say if it's a very distant model. 24:16.160 --> 24:17.600 Yeah, yeah, yeah. 24:17.600 --> 24:20.320 And in this festival, it's not so much the traffic increases, 24:20.320 --> 24:23.600 but the human increases, the noise of people and so on. 24:23.600 --> 24:26.640 And yes, it's much less an interest in size of the lab, 24:26.640 --> 24:29.200 because historically we work about some partition, 24:29.200 --> 24:32.480 but the closer model you can put, whatever the sun source you want, 24:32.480 --> 24:36.080 just at the front. 24:36.080 --> 24:40.640 I worked specifically on human noise sources. 24:40.640 --> 24:42.880 The most difficult is to find the density of the people 24:42.880 --> 24:44.000 where they are in the city. 24:44.000 --> 24:46.720 For a specific festival could be okay. 24:46.720 --> 24:52.080 But for city like Briggs and to know where people are speaking or shouting and so on, 24:52.080 --> 24:52.960 it's not so easy. 24:52.960 --> 24:56.400 The places are changing both the time and so it's difficult, 24:56.400 --> 24:59.760 but it's one research interest here. 24:59.760 --> 25:01.040 Yeah. 25:01.040 --> 25:03.040 Yeah. 25:03.040 --> 25:08.480 The most maps are to the mention of the further 25:08.480 --> 25:13.280 the calculations in the model are the three-dimensional. 25:13.280 --> 25:16.880 Yes, in fact, noise map, yeah. 25:16.880 --> 25:20.640 No map, I showed our two-dimensional, but the question is, 25:20.640 --> 25:23.120 if the calculation is three-dimensional, 25:23.120 --> 25:25.440 and I showed, like, two-dimensional, 25:25.520 --> 25:30.320 but the reservoirs that form matters over the floor, 25:30.320 --> 25:32.320 but you can put reservoir, whatever you want, finally. 25:32.320 --> 25:34.000 You could do three, three, three, 25:34.000 --> 25:36.000 no, it's map without any problem. 25:36.000 --> 25:39.600 The only thing is because we are using DA as platform, 25:39.600 --> 25:42.560 the pass-finding algorithm is like two-and-a-half-d, 25:42.560 --> 25:45.600 dimension, it's like a studied building. 25:45.600 --> 25:49.360 If you have, like, an art, the nice of a don't go inside the art, 25:49.360 --> 25:55.360 but there is not so much this kind of building in the world, so that's okay. 25:55.600 --> 25:56.560 Yeah. 25:56.560 --> 25:59.520 Um, it's very much real great, just a thing. 25:59.520 --> 26:04.960 I was wondering if you are familiar with a people-day noise map, 26:04.960 --> 26:07.040 so on the ground systems, because it's a thing, 26:07.040 --> 26:09.600 but if there's a place where you speak, I don't. 26:09.600 --> 26:10.640 Yeah. 26:10.640 --> 26:14.080 So, question if I am familiar with people doing 26:14.080 --> 26:19.280 underground noise map for transportation, transportation system, for example. 26:20.320 --> 26:23.840 Yes, and no, we are familiar with them when they are outside. 26:24.800 --> 26:27.680 Because sometimes, the control is going outside and going down. 26:28.720 --> 26:33.440 But when it's, yeah, when it's in close places, 26:33.440 --> 26:36.080 it's all the other models and knosos EU, 26:36.080 --> 26:37.280 and really specific one. 26:37.280 --> 26:41.120 And it's more, the same models that I use for architecture, for example, 26:41.120 --> 26:42.560 because close spaces. 26:42.560 --> 26:44.160 We also have an open source. 26:44.160 --> 26:45.760 In fact, it was the first software, 26:45.760 --> 26:48.080 an open source in the lab was for architecture, 26:48.080 --> 26:50.400 all acoustics, the name is Isapa. 26:50.400 --> 26:53.680 And is this software can be used for, for underground, 26:53.680 --> 26:55.680 for transportation, and similar as that one. 27:01.920 --> 27:02.560 All right. 27:02.560 --> 27:03.760 Yes, there's a question. 27:03.760 --> 27:06.320 You mentioned some, in terms of public collaboration. 27:06.320 --> 27:08.960 So, we have collaboration with OBR, the technologies, 27:08.960 --> 27:12.160 like some of which you can see, because much of a reflection, 27:12.160 --> 27:15.920 you work with the involvement of our advanced science, 27:15.920 --> 27:18.560 to the G, although are like this. 27:18.560 --> 27:23.520 Yes, so the question is about interdisciplinarity, 27:23.520 --> 27:26.160 and this kind of tools. 27:26.160 --> 27:30.000 In the lab, we are part of one institute, for example, 27:30.000 --> 27:34.960 with the Institute of Research of Science and Technics 27:34.960 --> 27:36.640 about the city. 27:36.640 --> 27:39.120 And inside this institute, there is all this. 27:39.120 --> 27:41.600 Most of the time it's your banner here, 27:41.600 --> 27:45.920 but inside this institute, you have like sociologist, 27:45.920 --> 27:49.600 your band studies and so on, and so on, and we work with them. 27:49.600 --> 27:52.480 For example, here, the guy you're doing this part 27:53.440 --> 27:56.320 is an economic, it's an economic transportation, 27:56.320 --> 27:59.040 an economic guy, for example.
