All of the above commenters seem to be looking for legislative or juridical solutions. There is an easier one, at least in this case. The young man, and if he gets no where (the chances of which are depressingly high) then his parents, should talk to their apartment manager and complain.

In a more systematic sense, a property owner has the right to play whatever noises-including these high-pitched tones-at whatever volume he pleases assuming it does not violate noise (or other applicable) ordinances. If a business owner has one of these and you dislike them for whatever reason (including being able to hear it #2) then decline them business and the forces of the market will work their magic.
