Connect a DB(A) loudness meter

This could be implemented in three ways:

1. physically, by integrating a microphone capable of accurately measuring and recording the sound levels produced by the aircraft shown on the display;
2. wirelessly, by connecting to a smartphone and using its built-in microphone to measure sound levels; or
3. similarly to option 2, but through a dedicated app designed specifically to measure, record, and log aircraft noise.

This is primarily a consumer product, but it could also be valuable to residents of cities and villages near airports. It would allow them to measure and record aircraft noise objectively, providing credible data that could form a solid basis for discussions with municipalities, airport authorities, and national government.
