Discussion about
Has anyone undertaken this type of renovation work? Looking at an apt that was split during coop conversion and noise complaints persist. The wall is prob 16-20 feet. Any experience to share? Cost? Best materials?

never done it before but have considered it a bit when i used to have a really annoying family with children that was a neighbor.

http://www.quietrock.com/ would be the cost of the materials..not sure what the labor costs would be tho.

it depends if you can afford to lose 4 inches in the width of where you are sound proofing. if not, then quiet rock is for you. if yes, then you can build a wall with 3" studs, egg crate foam (http://www.foambymail.com/Eggcrate.html) and regular sheet rock. i did the second option on a 23 ft wall with 8 ft ceilings with material costs of approx $250. the neighbors approached me once and said "Sorry for bothering you yesterday"... my answer was "I didn't hear a peep".

In the quietrock video they show a device the measures noise theat I am unfamiliar with. Are these devices expensive? Where can I buy one?

As a musician who has been to many studios (as well as a real estate agent) and discussed soundproofing with many people who care about this issue for a living--

I would ask first, what is the nature of the noise complaint, exactly? This sounds like a next-door-neighbor wall problem, not a downstairs-neighbor-wall problem, and that makes a helluva difference.

What kind of noises? Can they hear the TV, or phone conversations, or kitchenware being placed in the sink?

Because you want to know what frequencies are causing the trouble. By far the hardest to control, as every drummer knows, are the low frequencies. These sound waves are long and travel easily through hard materials.

If the neighbors are hearing clanking silverware, then it's a high frequency problem and my first question would be what is that wall composed of right now?

It's possible that just opening the wall and putting in R-19 fiberglas will solve your whole problem, which would be cheap (except nothing in Manhattan is cheap, but you know what I mean)

This is a big topic........the first step though is to understand the noise you are trying to abate.
