Bone Conduction Hearing Aids
SoundBite Hearing System
How does hearing work?Hearing [heer-ing], noun: the faculty or sense by which sound is perceived
Classification of Hearing Loss Conductive
Sound waves are not able to stimulate the sensory cells of the inner ear Sensorineural
Inner ear sensory cells or auditory nerve fiber are dysfunctional Mixed
Combined conductive and sensorineural Central
Affects auditory areas of brainstem and temporal lobe Functional
No pathological cause (believed to be psychological)
36 million Americans have hearing loss; conductive and sensorineural are the most common types (both can lead to single-sided hearing loss)
Causes of Hearing Loss Genetic
Otosclerosis; autoimmune inner ear disease
Ototoxic medications Damage sensory cells in inner ear
Loud noise Gradual or sudden
Physical trauma Damage to middle ear structures
Old age Diseases
Meningitis Tumor
Vestibulocochlear nerve
Types of Hearing Devices Hearing aid
5 different types Amplifies and modulates sound
waves Cochlear implants
Electronic device with under-the-skin portion and behind-the-ear portion
Electrode array directly stimulates auditory nerve
But there are other options…
Bone Conduction (BC) Devices Bone conduction carries sound through the
bone in the skull Transmits vibrations from hearing aid, through
the bone, and to the cochlea Example: ear plugs, chewing
Traditional BC hearing aid Bone anchored hearing aid
The non-invasive and removable solution to singled-sided deafness and conductive hearing loss using teeth by Sonitus
Medical• What is the SoundBite?
– ITM (in-the-mouth) device that snaps around the upper back teeth on one side– BTE (behind-the-ear) microphone that is worn on the impaired ear
How does it work?
1) BTE microphone picks up sound waves2) Digital signal processor processes the sound3) Wireless chip transmits to the ITM4) ITM converts signals into imperceptible vibrations that travel via the teeth to the cochlea
SoundBite in Detail Both the BTE and ITM are powered by rechargeable
batteries ITM lasts 6-8 hours BTE lasts 15-18 hours
BTE has a broad frequency range (500 Hz – 12 kHz) Teeth do not need to be altered ITM consists of sealed and flat battery, wireless
capability, and an actuator The ITM is hermetically sealed in a dental grade acrylic
Treatment Process1) Physician/audiologist visit
• Hearing evaluation and prescription
2) Dentist visit• Routine dental screening and impression taken
3) SoundBite Device is custom made by Sonitus Medical• Takes about 2 weeks
4) Audiologist visit • Programming and instructions
5) Replace approx. every 3 years• …or when device stops working
No surgery, no dental work, available within a few weeks = a very simple process
Clinical Trials - 2011 Multi-center trial using adults ages >18 and
<80 with permanent SSD and no current SSD device
Wore device for 8.2 hours a day for 30 days Results:
Improved ability of patients to understand speech in noise by an average of 25%
1/3 of the patients had improvement exceed 30% Significance: showed that SoundBite is as
effective as bone anchored hearing aids Murray, Michael, Gerald R Popelka, and Ross Miller. “Efficacy and Safety of an In-the-mouth Bone Conduction Device for Single-sided Deafness.” Otology & Neurotology: Official Publication of the American Otological Society, American Neurotology Society [and] European Academy of Otology and Neurotology 32, no. 3 (April 2011): 437–443. doi:10.1097/MAO.0b013e3182096b1d.
$ Cost $
The SoundBite costs $6,800 and is available in a pilot launch at 42 major hearing centers in the US Sonitus Medical hopes to win Medicare coverage before
making it more widely available Is currently covered by some private insurance
companies as a prosthetic device In comparison, the bone anchored hearing aid
costs approximately $10,000 and is eligible for Medicare reimbursement
SoundBite FAQs
Who is eligible? 18+ years, with SSD and/or conductive hearing loss and
good oral health Dental guidelines?
2 contiguous molar or premolar teeth with no untreated tooth decay
Healthy attachment with pockets no larger than 5mm No mobile teeth (dentures)
What are the contraindications for SoundBite? Allergies to device components (polymers) Hand handicaps
Can a patient eat/drink normally with SoundBite? Yes, it will not interfere Advisable to clean device after eating
In summary… No surgery needed (non-
invasive) Comfortable and custom-fitted Clinically proven Virtually invisible while worn
In the clinical trials, 95% of patients would recommend it to a friend who also had single-sided deafness
