New Paint designed to absorb sound.

[RoyY51]

This thread is off the curb.....and into traffic. First sound waves do not see paint, they see hard services. The sheen of the paint is not going to make a bit of difference at low frequencies, and there is no acoustical evidence it would effect the highs either. There is tones of acoustical research out there attributed to the effect of the shape of a space, the give of the walls, curves and reflective shapes, types of acoustical materials and their effectiveness at different frequencies, but I see zero on the effects of paint.

It IS amazing that this thread was resurrected after all this time.

Sir Terrence; you're almost there. You're undoubtedly correct when you say that "sound waves do not see paint, they see hard surfaces". The next step is to realize that as a paint gets shinier, it gets harder. Let me say this again; the shinier the paint, the harder the surface. This is why paints with higher sheens are used in kitchens and bathrooms, and on doors and woodwork. The harder surface that a glossy paint provides enables you to clean the surface more easily. A hard, shiny surface releases dirt much easier than a soft, porous one. It also reflects more sound. Stand in the middle of two empty rooms, one painted with semi-gloss, the other with flat. Clap your hands. The difference will immediately be apparent. Not a huge difference, mind you, but a difference nonetheless.

I'm sorry that you haven't been able to confirm this on the internet.I guess that there's just not enough of us painters/audio enthusiasts/forum dwellers around to make an impact on this narrow slice of arcane knowledge.
