In the spirit of knocking on the ceiling, I make thus suggestion:

When I lived in an apartment building, I learned that by performing pitch/pinch-harmonics around the 12th &13th frets on the B & G strings (when using high gain, distortion, bass) that the sound ressonates throughout the pipes in the surrounding apartments! It actually makes the pipes sing quite well, and is a GREAT deturant.

The people above me used to have two small boys that would stomp and play louder than the devil. When I couldn't take it anymore, I do harmonics until they'd stop and listen to the pipes and try and figure out what was going on. After about 2 weeks, I had conditioned them to stop playing every time I made the pipes sing!
