Sound vibrations travel through a medium, and sound is heard when sound waves travel through the medium of air or bones/teeth to arrive at the inner ears. The<unk>  uses sound waves travelling through bone, known as bone conduction to transmit subtle vibrations through bones to the inner ears. The<unk>  is a non-surgical and removable bone conduction<unk>  prosthetic device that re-routes sound through the teeth and skull bone directly to the functioning inner ear or cochlea. By-passing problems in the outer and middle ears entirely. For patients suffering from single-sided deafness,<unk>  re-routes sound from the deaf side, to the functioning cochlea, by-passing the non-hearing side.<unk>  uses the same mechanism of action as Baha devices (bone conduction), however it places a transducer on the tooth —a “naturally osseointegrated” post — and thereby eliminates the need for a surgical implant.<unk>  relies on two primary components to deliver sound: * The behind-the-ear (BTE) microphone unit is worn on the patient’s deaf ear. Using the natural acoustic benefits of the outer ear, sound is collected and channeled into the ear canal. A tiny microphone is placed within the canal of the impaired ear and is connected by a small tube to the BTE. The BTE uses a digital signal processor to process the sound and a wireless chip to transmit the sound signals to the in-the-mouth (ITM) device. * The ITM device is customized for each patient to fit around the upper, left or right, back teeth. The ITM picks up the signals from the BTE and converts them into subtle vibrations that travel via the teeth, through bone, and to the cochlea. Once these sound vibrations reach the inner ear, they are converted into auditory signals which are sent to the brain and are interpreted as sound. The BTE unit has a 12-to-15-hour operational life when fully charged. Each ITM<unk>  device has a 6-to-8 hour operational life when fully charged. The<unk>  includes 1 BTE, 2 ITMs, and a<unk>  charger. The BTE unit delivers a broader frequency bandwidth (up to 18,000 Hz) as compared to existing devices for single-sided deafness. This broader bandwidth enhances spatial<unk>  ability, which is a key limitation for SSD patients.
