Bone Conduction transmits sound vibrations through the skull bones directly to the cochlea, bypassing the eardrum and outer ear. It is used in sleep devices to deliver phase-locked acoustic stimulation without the risk of waking the user with ear-based headphones.
Key Applications
- •Sleep stimulation — delta wave amplification during SWS
- •Hearing aids — for conductive hearing loss
- •Low arousal — skull transmission is less likely to cause startle than air-conducted sound
