Airborne soundproofing of concrete floor
« on: February 22, 2010, 03:28:21 AM »
I have a condo on the 2nd floor. I can hear my neighbors downstairs talk as well as the tv. They are super annoying and make growling animal sounds all the time that are driving me nuts. I currently have concrete floors and it appears the sound is coming right through the concrete.  I am thinking of installing hardwood floors and want to know options I have to reduce the airborne sound.

Was looking at the product below, but I and am not sure if that would work. Would really like to keep the soundproofing material (not including hardwood floors) under $2 sq foot. Any ideas what my best options are?

Well there is something missing here.... What is the thickness of the concrete floor and what is their ceiling assembly below?
The concrete is an airborne sound barrier based on the density, so either the layer is thin 1 1/2" gypcrete or they are creating higher than 87db in their unit.
