Paint that helps diffuse sound?


A recent article in the Wall Street Journal about a doctor that built a new $3 million dollar house to house his own organ, indicated he used a specialty wall paint to to help diffuse sound. Anyone done the same?

Thankfully, I don't need $3 mil to house my organ.

And yes RF shilding paint does exist
A rough surface will diffuse the sound. Sound will travel along a smooth wall and a hardwood floor, like a wing it will sail. You can mix your own paint. You just need to know what to add. Tom
