Regulatory Classification
Identification
A tinnitus masker is an electronic device intended to generate noise of sufficient intensity and bandwidth to mask ringing in the ears or internal head noises. Because the device is able to mask internal noises, it is also used as an aid in hearing external noises and speech.
Special Controls
The special control for this device is patient labeling regarding:(1) Hearing health care professional diagnosis, fitting of the device, and followup care, (2) Risks, (3) Benefits, (4) Warnings for safe use, and (5) Specifications.

#### Device Description
The Tinnitus Sound Generator provides a means for healthcare professionals to create a hearing instrument solution that provides relief for Tinnitus patients. This software solution is embedded into a digital hearing instrument platform, so that the end-user can wear this device in all environments. The fitting of the digital device, which contains the Tinnitus Sound Generator module, is performed by a healthcare professional, in order to meet the exact needs of the Tinnitus patient.
A mobile medical application (app) is available as an optional device to use with the Tinnitus Sound Generator. The mobile medical app allows the user to adjust the hearing aid within the limits set by the healthcare professional during fitting of the hearing aid. The app is known as the TSG Tinnitus Manager app.

#### Intended Use
The Tinnitus Sound Generator Module is a tool to generate sounds to be used in a Tinnitus Management Program to relieve patients suffering from Tinnitus. The target population is primarily the adult population over 18 years of age. This product may also be used with children 5 years of age or older.
#### Indication for Use statement
The Tinnitus Sound Generator Module is a tool to generate sounds to be used in a Tinnitus Management Program to relieve patients suffering from Tinnitus. The target population is primarily the adult population over 18 years of age. This product may also be used with children 5 years of age or older.
The Tinnitus Sound Generator module is targeted for healthcare professionals, which are treating patients suffering from Tinnitus, as well as conventional hearing disorders. The fitting of the Tinnitus Sound Generator module must be done by a hearing professional participating in a Tinnitus Management Program.
#### Technological Characteristics Comparison
There are seven modifications (Microphone always enabled, Shared volume control for TSG noise level and microphone inputs, Shared synchronization control, Removed smooth transition when switching towards one of the AM attenuation modes. White noise bandwidth extended from 7 kHz to 9.5 kHz. Low pass filter extended to 8kHz, and New coding language on C5 platform).
The revisions to the Tinnitus Sound Generator module are technological software advancements that improve the functionality of the device, whilst having minimal risk to the patient and are minor modifications in relation to the predicate device that do not change the operating principle of the TSG module.
#### Performance Data
GN Hearing has conducted a risk analysis and has performed the necessary verification and validation activities to demonstrate that the design outputs of the modified device meet the design input requirements.
Successful Verification is done one-to-one for all product requirements, with proper traceability. The verification shows substantial equivalence to the predicate device, also verified in house. The verification also includes a successful System Verification including all the devices interacting with the modified device.
Successful Validation is done with focus on evaluating stability, clinical performance and the objective and subjective benefit of the modified device. The Validation is done as part of a System Validation, including all the devices interacting with the modified device. The Validation show substantial equivalence to the predicate device, also validated in house.
#### Other - Pediatric Use Precautions
The target population is primarily the adult population over 18 years of age. This product may also be used with children 5 years of age or older. However, children and physically
{5}------------------------------------------------
or mentally challenged users will require training by a doctor, audiologists, hearing care practitioner or the guardian for the insertion and removal of the device containing the TSG module.
Children and physically or mentally challenged users will require guardian supervision while wearing the device.
#### Conclusions
Modifications to the device do not raise new or different questions of safety or effectiveness for the device's intended use. The results of risk analysis and design verification and validation activities provide evidence that the device is as safe and effective as its predicate. This therefore demonstrates that the TSG module is substantially equivalent to its predicate device.
