And yes the nervous system is in play, but sound (oscillation) moves through the body far faster than nerve impulses to the brain ...
Alll energy has waves and all waves oscillate. Nerve impulses are electricity. Waves are said to be an "energy transport phenomenon" and can transfer energy without transfering matter.
Btw, clever idea to reference a blog to a thread, as both elicit responses, but it uses up exponentually more bandwidth.
