I never knew about this technology until I read it over at OhGizmo.com. Bone as the conductor and our palms as the earphone? Hmmm… Really an interactive invention.
It’s simply rest your elbows on the metal rail an cover your ears with your hands. Those who touch but not covering their ears won’t anything else or feel anything.
My question is, if the environment is noisy, will this touched Echo lost the sounds? Well, nobody know until they try it!
