is the unusually loud hearing of a person's own voice, breathing or other self-generated sounds.
- The Occlusion Effect
- Open or Patulous Eustachian tube, allowing vocal and/or breathing sounds to be conducted into the middle ear.
- Otitis media, inflammation of the middle ear
- Superior canal dehiscence, which can lead to an abnormally amplified bone conduction of sound into the inner ear. Persons with superior canal dehiscence syndrome (SCDS) typically hear not only their own voice but also heartbeat, skeletal sounds (e.g. when running or eating) and possibly even the sound of their eye movements when reading.
