Abstract
An implantable hearing instrument is provided that reduces the response to unnaturally high vibrations (e.g., due to a patient's own voice), without necessarily or substantially affecting the response to desired signals. The implantable hearing instrument system is operative to selectively alter/lower the gain of signals that have a magnitude above a predetermined threshold. Signals having unnaturally large amplitudes (e.g., due to a patient's own voice) are amplified less than desired signals, so that a patient may experience a more representative sound.
