My neighbors (a couple with children) bought a new flat-screen tv which they mounted on the wall that we share with them. From the day they mounted the tv, we here this thumping sound coming through this shared wall, even at low volumes (My neighbor and I tested it and confirmed it was the new tv). Although they understand the problem they do not want to remove it from the wall. I did not ask them directly (yet), but their argument goes: 'we sometimes hear also noise from your house'. Ironically the volume of their tv goes down when their children go to bed around 8:30
I tried explaining that there are different types of sounds: 'peak' sounds which last a short time and are incidental (e.g. somebody shouts, or drops something on the floor), incidental sounds that last a little bit longer but are still incidental (e.g. loud conversation, turning the volume very high for your favorite song once in a while), and periodic long lasting sounds (like turning on the television every day for several hours). There are probably more categories but these are perhaps the most important ones for this particular issue.
My point was that most of the sounds they hear (and I hear from them) fall in the incidental (usually man made) category. But a television sound every day for several hours is slightly different (at least to me).
My question is what to do? Below (in order of preference) some options I might have. Only option one looks appealing so far.
* Look for a technological solution. I think the sound is propagated through the wall as the acoustic tv is directly mounted on a hard surface (the wall). Are there any (proven) solutions for hard surface to hard surface mounting? E.g. some kind of soft material that can 'dampen' the sound (although there are still screws involved)
* Ask them to remove the tv from the wall or turn down the sound substantially (although the sound is already turned down a lot)
* Is there a legal solution for this (can I force them to remove it)?
* By a bigger television with bigger speakers and mount it to the same wall
Do people have any other suggestions (other than wearing noise canceling earphones in the house)?
Is there any scientific research on the topic of noise nuisance and pollution that shows what kind of noises are (on average) tolerable or not or highlight these kinds of noise problems?
