The idea here is very similar to the one that was about producing soundproof windows. Only this time you would produce a pane of material that filters selective frequencies or a narrow range of frequencies.

Then you would tune it specifically to the frequency you need. Say there is an neighbour alarm going on, it senses and tunes to that frequency. It is grasscutting time, tune to another, and so on.

No, I really don't have nothing to complain about my neighbors. Lol.
