Hello, regarding aircraft noise, it depends. Suppose you are a homeowner annoyed by planes passing close to your home. In that case, any good quality sound level meter can help you analyse precisely the noise level generated by air traffic. If you are a professional working at the airport, tools exist to create a link between airports and local communities. You can then manage aircraft environmental parameters (noise, air quality…) with a flight track management system providing all the tools needed for monitoring, analysing and communicating on environmental impact. The best example I've got is the one I know, which is Acoem Aerovision.
