Soundproof paint is a specially formulated paint that contains sound-absorbing particles. Once it’s applied to a surface, it creates a thin layer between the wall and whatever sound it’s intended to absorb. That might sound like science fiction, but to the credit of the manufacturers, it does work how it’s intended…sort of.

There is no such thing as soundproof painting. Paint is not a barrier technology. A barrier is a material or structure that you place between the source of the noise and the receiver of said noise. Barrier material types are frequency and amplitude specific.

Soundproofing paint doesn’t soundproof. Instead, it’s a good sound absorber, just like acoustic foam and wallpapers, among other sound-absorbing materials. If it does absorb sound, why does it not qualify as a soundproofing material? The concept is simple- soundproofing involves eliminating unwanted soundwaves from source to the listener.
