Bone Conduction

A method of sound transmission to the inner ear through the bones of the skull, allowing the hearing of sound without use of the ear canal.

Proximal Auditory System

Refers to the part of the auditory system that is closest to the source of sound, typically involving structures of the inner ear and early stages of auditory processing.

Tiny Bones
