Reggaeton Be Gone (the name is a homage to Tv-B-Gone device) will monitor room audio, it will identify Reggaeton genre with Machine Learning and trigger comm requests and packets to the Bluetooth speaker with the high goal of disabling it or at least disturbing the sound so much that the neighbour won’t have other option that turn it off.
This may not work for everyone, and the Bluetooth needs to be in range, but I thought it was a particularly interesting technical solution to a real-world problem. It can be probably adapted for other music genres too.
