MLV - Under New Flooring
I stumbled upon a Youtube video called "Sound Proofing Secret that Actually Works".
In it the Contractor states the secret is placing MLV between sub-flooring and carpeting/hardwood will reduce the sound coming from the above floor into the finished basement/home theater.
States this is much cheaper and easier than putting clips, hat channel, 2 sheets 5/8”drywall, and GG. If find this is hard to believe. I believe it can help with the sound coming into the theater but I’m skeptical it will do as much with the sound escaping from the theater. Thoughts?
