Ok so it happened again... my students asked a question I hand't thought of before (love it when that happens!) Can you help me? What happens to the sound wave after it hits the eardrum? Does it get absorbed, or does it continue to go through your head? I found lots of info about how the sound wave interacts with the ear, but then there's no info on if the wave continues after vibrating the ear drum (is there any energy left?) Any ideas are appreciated!
