Bone conduction

Bone conduction is the conduction of sound to the inner ear through the bones of the skull. Bone conduction is one reason why a person’s voice sounds different to him/her when it is recorded and played back. Because the skull conducts lower frequencies better than air, people perceive their own voices to be lower and fuller than others do. This also explains why a recording of one’s own voice sounds higher than one is accustomed to.
