**Air Conducted Sound and Bone Conducted Sound** Normally, "hearing sound" refers to the ears capturing vibrations in the air. Sounds that are transmitted through vibrating air are called "air conducted sound." In contrast, sounds like those used by Beethoven, who had hearing loss in his later years, are transmitted through vibrations in the bones and are referred to as "bone conducted sound." **Bone Conducted Sound is Always Heard!** It's easy to confirm bone conducted sound. Try covering your ears and speaking. Even though you shouldn't be able to hear the sound through your ears, you should still hear your own voice. That is bone conducted sound. Your voice vibrates the skull, and those vibrations are transmitted to the cochlea, allowing you to hear the sound. For more details, please contact us or download the catalog.
