In order to better understand bone conduction sound propagation across the skull, three-dimensional (3D) wave propagation on the skull surface was studied, along with its dependence on stimulation direction and location of a bone conduction hearing aid (BCHA) actuator. Relied on by the hearing impaired community and musicians among others, bone conduction speakers are even used by scuba divers and some hearing aids also employ bone conduction. In general, the stimulation for BC occurs on a specific location directly on the skull bone or through the skin covering the skull bone. This type of speaker turns any surface into a speaker, duplicating the sound waves over and over through the surface giving you a fuller richer audio experience.
