Incessant horn honking and blaring car stereos, both of which are significant noise contributors won't be included? Does that make any sense? If the goal is to bring the noise pollution under control via the use of sound cameras why would you limit it to mufflers? The sound camera device's metric is decibels. Why should the program discriminate the source of noise pollution?
- _carbyau_ 4y agoNot sure but maybe it is a "sound signature" thing. IE it might be possible to automate matching a car based on exhaust noise. But not for a song on the stereo.
- bogomipz 4y agoI don't think so. The device I believe they are using is the same one as in France - the "medusa" technology by Bruitparif. This document shows the device picking up cafe noise vs construction vs street cleaning. There's some details here: https://www.euronoise2018.eu/docs/papers/124_Euronoise2018.pdf https://www.euronoise2018.eu/docs/papers/124_Euronoise2018.p...
- _carbyau_ 4y agoThat is cool. I was thinking pattern matching sounds and then matching a pattern through logical association. IE same pattern at two different spots implies the car is at those same two spots. But this is literally viewing the world through sound pressure levels. It doesn't care what the noise is, as long as it's loud. Which fits the use case here.
