I live on a very busy road that sees >15,000 vehicles/day, including 18 wheelers, dump trucks, busses, tankers etc. It is noisy (nevermind the air pollution) from 5:30 AM to 10:30 PM and I don't think local officials really appreciate it. I'd like to capture data, I'd even pay for it, but all of the "sound level" measuring devices are all junky and don't give accurate readings and don't store the data really well. I'm happy to pay for the right device or even better some certified service that can take measurements and create reports but I'm lost here. Any advice?
