i am moving to another house soon, one i have bought which is around 47 year old so hopefully the walls will be quick thick, its a mid terraced house. I want to know how to prevent sound annoying the neighbours, everywhere i have stayed i have had complaints about the music/movies i play needing turned down even though it was not that loud the bass just seems to travel through modern houses so easily. Anyway i was wanting to know if there is any measures can be taken to help me play my music at a decent level without annoying anyone. I dont want to go to great expence but what is the most effective way of soundproofing without too much hassle or cost. I intend to lay down laminate flooring in the living room (14' 10" x 12' 10") so would it help if i used the thick green felt sheets rather than the thin white foam stuff. Does carpet and underlay do a better job of keeping the sound from travelling? Or is there no difference between laminate flooring and carpet? My system at the moment is a sony davs-880 which is the one with the 4 tall slim floor standing speakers, centre speaker and subwoofer box on the floor. I know the speakers themself wont be creating any bass but any suggestions what i can do with the subwoofer box to reduce the bass travelling. any suggestions on sound insulating greatly appreciated also is there any way i could measure the level of bass i can play ie try different levels to find what is noticable by my neighbour then use the meter to measure the level of bass and try and not go above this level, would this work ?
