A New Sound Transmission Pathway

A new sound transmission pathway called "cartilage conduction" has been gathering attention. Unlike bone conduction, cartilage conduction creates sound within the ear canal. It can be used to make smartphones that can be heard clearly in loud places and earphones that don't leak sound. Then we have a bone conduction technology that makes ultrasounds audible. We'll be covering potential new solutions for those with severe hearing loss that aren't able to use conventional hearing aids.
