SoundBite Hearing System works by making innovative use of the well-established, natural principle of bone conduction – the transmission of imperceptible sound vibrations through the bones to the inner ears – to deliver clear, natural, high quality sound.

Nearly invisible when worn, the SoundBite system consists of two components: an easy to insert and remove ITM (in-the-mouth) hearing device and a small BTE (behind-the-ear) microphone unit worn on the impaired ear. No dental work or modifications to the teeth are required. Both components have rechargeable batteries and a system charger is also provided.

Microphone Unit

To take advantage of the natural acoustic benefits provided by the patient’s own ear, sound in the environment is picked up by a tiny microphone placed within an open fit dome worn in the canal of the impaired ear and connected to the BTE by a small translucent tube. The BTE uses a digital signal processor to process the sound and a wireless chip to transmit the signals to the ITM hearing device, which in turn sends imperceptible vibrations via the teeth near-simultaneously to both cochleae. In this way, sound is rerouted from the impaired ear directly to the good cochlea – bypassing the middle and outer ear entirely – to effectively restore the perception of hearing from the impaired ear. SoundBite Hearing System delivers sound across a broad frequency range of 500 Hz to more than 12 kHz.

The ITM device is custom made to fit around either the upper left or right back teeth, does not require any alteration of the teeth, and is easily inserted and removed by the wearer. It contains electronics, a sealed, flat, rechargeable battery, wireless capability that picks up sound transmissions from the BTE, and a small actuator that converts those signals into vibratory energy. All of these miniaturized components are hermetically sealed inside a dental grade acrylic that has been safely used for making dental appliances for many years.

System Charger

SoundBite does not require changing batteries. A system charger powers both the ITM Hearing Device and BTE microphone unit. The charge lasts 6 to 8 hours for the ITM and 15 to 18 hours for the BTE.
