More on Apartment Noise
I currently live in a large c. 1960's rental building. It is supposedly well-constructed with concrete of sorts between apt.'s (and rooms) and is fireproofed.
Still, the walls and floors transmit sound copiously and may even to be amplifying it. I can hear when the pelple next door to one side run their sink, to the other side when they take a shower, coughing and laughing from above, and (needless to say) TV's, radios and ringing phones from seemingly every direction. From outdoors is bad too when lawns are being mowed or kids of all ages are playing downstairs.
I will soon be moving but it will unfortunately need to be another apartment or loft (NY City). Can anyone suggest (non-technically) what might be wrong with the construction of where I live now and what features I should look for next? Thanks for your help.
