Bone conduction

Bone conduction

Bone conduction is a method of transmitting sound vibrations through the bones of the body, bypassing the outer and middle ears and directly stimulating the cochlea in the inner ear. This can be achieved through the use of a bone conduction receiver, which may be preferred over headphones in certain situations where the ear canal needs to remain open.From: Acoustics and Psychoacoustics [2019], Encyclopedia of Biomaterials and Biomedical Engineering [2019], Electroacoustics [2019]

This air-borne sound transmission system via the eardrum and the middle ear is not the only channel through which we hear. Hearing also takes place through bone conduction of the skull. This occurs when crunching a biscuit or when humming and speaking. Hearing by means of bone conduction by-passes the middle ear.

Because of the occlusion effect (Section 14.3.3), sensitivity to bone conduction below 2 kHz is raised by 10-25 dB when an earphone is worn over the test ear. Therefore, BC audiometry should be performed in a soundproof room with the test ear free131.

The principle of bone conduction has been in use in hearing devices for many years. Surgical techniques and the devices themselves have continued to develop and have progressed rapidly since multiple companies entered the market and competition between them developed. Active middle-ear implants also have a role to play and the indications for many of these devices overlap. It is important that physicians offering hearing implants have an understanding of the available devices in order to counsel patients and provide them with the most suitable device.
