I know most people hear from 20hz to 20000hz and about the absorption spectrum of water absorption spectrum of water link but how deep does sound travel when it hits the skin and which range of frequencies travel the farthest when it hits skin. Basically what is the absorption spectrum of skin in respect to sound. Does a chart exist that has a large range from sound to light wavelengths? Can this be calculated?
I was interested when I read this article Music for the skin: a Nova program made by PBS link
