compression bone conduction

Compressional bone conduction is a method of hearing where high-frequency sounds cause skull segments to vibrate individually. These vibrations compress the bony case of the inner ear, stimulating the sensory cells responsible for sound perception. This process allows sound to be transmitted through the bones of the skull directly to the inner ear, bypassing the outer and middle ear structures. This is distinct from inertial bone conduction, which involves the vibration of the entire skull at lower frequencies.12
