I'm new to this forum, but lurked for a few months before posting anything.
I'm in the process of soundproofing a room and researching my soundproofing options. My goal is to limit footfall noise from above, and voices (airborne sound).
So far, I've read through articles by Ted White, numerous posts by BigMouth in this forum, and articles from the soundproofing company and so forth.
From what I gather, the 4 basic principles of soundproofing are key (mass, decoupling, absorption, damping). Along with Flanking noise.
I'm leaning towards building the ceiling assembly from The Soundproofing company (can't post the URL because i'm under 5 posts).
During my research process, I stumbled on these products from a Canadian company called MSL fibre. Two products stand out to me, but the claims are unsubstantiated by any real reviews except a few posts on instagram, and limited forum posts.
My question are the Sonopan and Reflexor products (which i'm still a bit skeptical of, but curious).
Sonopan is essentially a fibreboard that's supposed to have an STC of 27.
Reflexor is supposed to be a greenglue replacement.
Does anyone have any experience with the Sonopan and Reflexor products?
Should I just "play it safe" and build the assemblies shown on The SoundProofing company's website?
The Room is about to be gutted, so I'm starting from scratch. Budget isn't a factor. I just want the job done right. The sonopan+reflexor assemblies claim an ASTC of up to 61, but it sounds too good to be true.
Really appreciate anyone's comment and feedback before I start ripping the walls out
