## Indications for Use
The indication for use of the air conduction hearing aids in this submission is to amplify sound for individuals with impaired hearing. The devices are indicated for individuals with losses in the following category(ies). (Check appropriate space(s)): Severity: 2. Mild, 3. Moderate, 4. Severe. Configuration: 1. High Frequency -Precipitously Sloping, 2. Gradually Sloping, 4. Flat.
## Device Story
Sound F/XD is a programmable mini behind-the-ear (BTE) hearing aid; functions as an air conduction hearing aid to amplify sound for hearing-impaired users. Device is worn behind the ear; operates via internal circuitry to process and amplify acoustic signals. Intended for use by individuals with specific hearing loss configurations; fitted and programmed by hearing healthcare professionals. Output provides amplified sound to the ear canal to improve auditory perception. Device is subject to general controls and potential electromagnetic interference from digital cellular devices.
## Clinical Evidence
No clinical data provided; substantial equivalence is based on device classification and intended use for air conduction hearing amplification.
## Technological Characteristics
Programmable mini BTE (behind-the-ear) hearing aid; air conduction type. Class I device (21 CFR 874.3300).
## Regulatory Identification
An air-conduction hearing aid is a wearable sound-amplifying device intended to compensate for impaired hearing that conducts sound to the ear through the air. An air-conduction hearing aid is subject to the requirements in § 800.30 or § 801.422 of this chapter, as applicable. The air-conduction hearing aid generic type excludes the group hearing aid or group auditory trainer, master hearing aid, and the tinnitus masker, regulated under §§ 874.3320, 874.3330, and 874.3400, respectively.

K974339 Unitron Model Sound F/XD Programmable Mini BTE Hearing Aid Dated: November 7, 1997 Received: November 18, 1997 Regulatory class: I 21 CFR 874.3300/Procode: 77 ESD
Dear Ms. Archer:
We have reviewed vour Section 510(k) notification of intent to market the device and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
This letter will allow you to begin marketing your device as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
While your device has been deemed substantially equivalent to other legally marketed hearing aids, please be advised that electromagnetic interference from digital cellular telephones, as well as from other sources is increasingly becoming a concern. Typically, this interference takes the form of a buzzing sound that can range from annoying to very loud and may render a hearing aid temporarily ineffective for the wearer. Because electromagnetic interference may affect your device, you may be asked to test for electromagnetic compatibility in the future. In this interim period, we encourage you to modify your device labeling to inform practitioners and users of the potential for electromagnetic interference. Please be aware that a 510(k) submission is required for any claims that infer that your device is compatible with potential sources of electromagnetic interference, such as "compatible with digital cellular telephones", and that data supporting such claims is necessary.
