Brief Summary:
This study is designed to collect data about the SoundBite™ Hearing System to answer specific questions. The hearing system has been cleared for commercial distribution by the Food and Drug Administration (FDA). Sonitus hopes to learn from a larger group of users what features and settings of this device provide the best hearing ability for people diagnosed with Single Sided Deafness (SSD) or Conductive Hearing Loss (CHL).

Condition or disease
Single Sided Deafness Conductive Hearing Loss

Detailed Description:
The Sonitus SoundBite Hearing System prosthetic device is a bone conduction device that has been FDA cleared for treatment of single-sided deafness (SSD) and conductive hearing loss (CHL). The Sonitus SoundBite Hearing System consists of an In the Mouth (ITM) component an external microphone component, worn behind the ear (BTE), a calibration interface cable and PC-controlled calibration software for subject calibration. A charger is also provided to charge the ITM and the BTE. The objective of this multi-sites observational study is to assess the long-term patient use of the Sonitus SoundBite Hearing System.

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
All trial subjects are individuals that have decided to purchase SoundBite Hearing System for treatment of their Single Sided Deafness or Conductive Hearing Loss and are willing to participate in this study.

Inclusion Criteria:

  • Patients who are 18 years or older
  • Clinical diagnosis of a Moderately severe, severe, or profound sensorineural hearing loss in one ear and normal hearing in the other ear (Normal hearing is defined as a pure tone average (PTA) air-conduction (AC) hearing threshold (measured at 0.5, 1, 2, and 3 kHz) of better than or equal to 25 dB HL)
  • Patients diagnosed with conductive hearing loss where the pure tone average bone-conduction hearing threshold (measured at 0.5, 1, 2, and 3 kHz) is better than or equal to 25 dB HL.
  • At least two contiguous molar or premolar teeth with no untreated tooth decay. -Patients with tooth decay present are to first have restorations before being fitted for SoundBite
  • Healthy attachment to those teeth with tooth pockets limited to no more than 5mm
  • No mobile teeth
  • Bone loss no greater than a 34% average on the mesial and distal sides of the tooth as measured on X-ray on the teeth on which the device will be worn.

Exclusion Criteria:

  • The SoundBite Hearing System and all portions of it are contraindicated for use in an MRI Environment and should be removed prior to MRI exposure
  • The SoundBite Hearing System is not to be used in patients with known hypersensitivity to any of the components including allergies to polymers.
  • The SoundBite Hearing system is contraindicated for vulnerable populations that are unable to sue their hands such as paraplegics or others that are unable to comply with the warnings in the product's labeling.
