We live in a relatively quiet area. Since 2012, we hear a low bass rhythmic sound (music?) with slight vibrations in the front bedroom. We cannot hear it outside, only in the room and especially while lying in bed.
A sewer pipe runs underneath that bedroom. We've had it checked and rechecked, but it has revealed nothing. There is a city water pump down the street, but the sounds do not match.
Could a neighbor's Bose sound system across the street travel via pipes to our front bedroom?
Nothing really is heard outside and the sound is mostly at night.
If it is a Bose-like system, and neighbor does not want to turn music off, what can we do?
