Anyone knows of a DIY Arduino / RaspberryPI project for precisely measuring noise levels outdoors? I find many projects called "decibel meter" but they only light up LEDs. I'd like to log values to show how annoying some motorbikes can be in some cities. #city #noise
To get more context about why I'm asking for this, see this e-mail exchange with the city council of Palma de Mallorca about noise: https://pastebin.com/6FvtwUe7 (English) or https://pastebin.com/4HCPtLF9 (Español) #city #noise
My thought was that if the city council does nothing about it, one could present noise measurements and plate numbers of offending vehicles and send a complaint. I did some recordings, I'll share some examples in this thread.
Oh https://sensor.community/en/ has a noise module! Reading about it at https://sensor.community/en/sensors/
This seems to be
