I recently had an great conversation with Doug Johnson, the Sales and Marketing Manager at Kinetics Noise Management, which specializes in a broad range of soundproofing work from tacking noise issues in commercial properties to installing high-end home theater systems. I am dividing my basement into non-complementary spaces (one a home office and the other a play space for children) and Doug spent a lot of time with me on the phone just to get me up to speed about what issues I need to address. He offered the solutions that were best for me, even if they were ones that I could easily purchase other places, though of course my preference is to use Kinetics all the way through my project. Doug is highly professional, very knowledgeable, patient and overall very pleasant to work with. I enthusiastically recommend him as your first stop to solving whatever soundproofing issues you may have.
