Acoustic treatment

Deprogrammers are standing by. You can’t use that shear velocity baloney for everything. You can’t use it for isolation, much less tiny little bowls. It’s a nice day. Go out and get drunk.

“If I could explain it the average person they wouldn’t have given me the Nobel prize.”

The tiny bowls shape and material determines the shear wave pattern and velocity that makes the sound changes in the air. Copper, Silver, Gold and Platinum all have a diferent shear speeds and they all result in a different acoustic out come.
Put a stone or diamond if front of all that hang it on a wall and you have an acoustic resonator. All starts with material or materials and shape..keep looking. Tom

Enough jibber jabber. The reason tiny little bowls work is that the diameter of the bowls and corresponds to an acoustic wavelength AND an electromagnetic wavelength. That’s why Franck Tchang was able to *measure* effects up into the GHz range. In the acoustic domain the tiny bowls “equalize sound pressures” in the room by reducing (absorbing) unwanted high sound pressures like standing waves. We know that’s how they work because the high pressure zones in the room is where the tiny bowls are located ideally. Hel-loo! In the electromagnetic domain the tiny bowls absorb rf. It’s an acoustic resonator. And an electromagnetic resonator. It’s nothing so mysterious and goofy as shear wave velocity.

So you don't know the origins of sound. Tom
