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?

I'd love to know how a flat paint film could diffuse sound? Sounds like a case of a reporter unfamiliar with acoustics using the word diffuse when they meant dampen. There is sound absorbing or dampening paint. If there were a textured "diffusion" paint, its diffusion characteristics would have to limited to extremely high frequencies (unless someone has figured out how to circumvent the laws of physics and acoustics.)
The thing I find more incredulous than sound diffusing paint is that a doctor is able to purchase a $3 million house. At least for those of us who are younger physicians, the only thing we'll have approaching $3 million is our student loans.

Stealth paint- iron balls, nano-tech, etc. to make aircraft invisible to radar. I
think it absorbs, rather than diffuses. To paraphrase Michael, the thing i find
incredulous is the line about building a house to 'house his own organ.' But,
I'll leave it at that. :)
PS: just found the article online. Pretty interesting- I grew up outside of
Pgh, PA, and a neighbor had a barn that housed a huge pipe organ that
this man had worked years to restore and assemble. Labor of love. I say go
for it if it makes you happy.
