Halocho #1975 - Noise pollution

If one has a neighbor who suffers from headaches caused by noise, one must be considerate and be careful not to make unnecessary noise. 

E.g.: one may not use a hammer if a neighbor will hear it and suffer.

The same would apply to loud music during siesta time or after they have put their kids to bed.
