Title: Totally soundproofing a theatre room so that no one outside can hear.
Post by: thetone on May 18, 2010, 10:28:18 PM
I have been looking at different products to accomplish soundproofing. I want to isolate the sound of one room from the rest of the house. I am convinced at this point that I need a box inside of a box, but am not sure about the products on the walls. The floor is concrete. I have looked at limp mass vinyl, but it is terribly expensive. I would like to know if I can use a substitute for limp mass vinyl like a roofing membrane EPDM or a shower pan product which is PVC vinyl. This would be cheaper. The two products seem to be very similar.  In addition, I have checked this Green glue product, but did not know whether or not it is as good as they say it is. I am a contractor and have used quiet rock before. I wasn't impressed with it. Can you help with this?

Your on the right track with the room inside of a room method...I think if you contact me directly we can spend a little time discussing the principles and methods of approach which will in turn give you a far better understanding why materials dont always work out.

Greetings from Sound-Answers.com

Total isolation requires substantial construction, especially when you are dealing with home theaters and the very low frequencies present.  Box-in-box construction for this extreme of a sound source (home theater) and sensitivity of receiver (bedrooms) may involve a floated floor, decoupled walls (on the floated floor) and a resiliently hung sound control ceiling.  We suggest you visit Kinetics Noise Control (http://www.kineticsnoise.com/arch/index.aspx) and download their ‘Architectural Noise Control Brochure’.  It will help you appreciate the level of degree we are talking about.  We wish you the best of luck!

Absolutely we only use Kenetics Clips in our system for floating off existing structure and we feel it delivers the best results when working on existing structure...however, a true room inside of a room that only has the potential to share structure at the base plates of the wall and installing a floating floor system is another method of achieving great results without the risk of shorting the floated system.
