Concrete Floor Sound Transmission

Post by Winton »

I also posted this in the building materials area.

I know this is a bit far afield for this site, but I'm having a hard time locating info.

I'm on the Board of a high rise condo association. Some residents would like to convert an empty space into a party room, even though it has residential suites directly above it, separated only by a concrete floor.

I, along with many others, have argued that while it may be very doable to eliminate much of the sound transmission to the units upstairs, there is nothing, or at least nothing that is remotely cost-effective that could deaden to virtual imperception the sound transmission of an electric bass in a medium-loud to loud rock band, from the proposed party room to the suites directly above.

The other proposed uses of the 4,000 square feet of space are 1, as commercial offices for tenants in typical 9 to 5 weekday professions (law, accounting, architecture) or, 2, using it for a fitness center. I have some small concerns about the fitness center alternative vis a vis noise (clinking of weights, etc.), but I'm pretty confident that those sounds can be damped with ceiling material.

The ceiling is about 12 feet high.

Does anyone know of a publication that might shed light on all of this in an authoritative way, and that I could use to persuade those fellow residents who are living in a parallel universe and believe the rock band sound transmission won't be a problem? Many thanks.

Hee is a document that will you explain the losses of floors.

There is a gold mine of info at the NRC. Here is a link to their general search engine with sound isolation already pulgged in.

What your fellow neighbors want to do IS achievable. The question is cost.

Good luck!
