Device Story
PRISMA hearing instruments are wearable, digitally programmable devices available in Behind-the-Ear (BTE) and custom (ITE, ITC, Half Shell, Mini-Canal, CIC) form factors. Devices utilize a digital signal processor to amplify and transmit sound to the ear. A hearing professional programs the device using PC software (Siemens CONNEXX) and hardware (HiPro) to match the user's specific audiogram. Features include channel delineation, various compression modes (curvilinear, linear, syllabic, dual), voice activity detection, and directional microphones. Users may adjust settings via on-device switches (M-T-O, memory toggle) depending on configuration. The device compensates for moderate to severe hearing loss, improving auditory perception for the patient.
Clinical Evidence
Bench testing only. The device complies with ANSI S3.22-1987 specifications for hearing aid performance.
Technological Characteristics
Digital signal processor; programmable via PC software (CONNEXX) and HiPro hardware; BTE and custom form factors; powered by standard hearing aid batteries (5A, 10A, 13, 312, 675); frequency response dictated by individual audiogram; features include directional microphones and dual memory storage; technical specifications comply with ANSI S3.22-1987.
Indications for Use
Indicated for individuals with impaired hearing to compensate for moderate to severe hearing losses, including flat, ski-slope, and reverse slope losses.
Regulatory Classification
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.

## A SUMMARY OF SAFETY AND EFFECTIVENESS INFORMATION
| Name of Device: | Siemens PRISMA Behind the Ear and Custom Hearing Instruments |
|----------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| | SEP - 5 1997 |
| Type of Device: | Behind the Ear and Custom Hearing aid substantially equivalent to other Behind the Ear (BTE) and Custom hearing aids (In The Ear, In The Canal, Half Shell, Mini-Canal, Completely In the Canal) on the market. |
| Intended Use: | To amplify and transmit sound to the ear. |
| Features: | PRISMA Behind the Ear and Custom Hearing Instruments are digitally programmable instruments. The dispenser programs the instrument using Siemens PC CONNEXX software with HiPro ™ hardware (K942749), Siemens Personal Programmer 2000, or UNITY with HiPro hardware This device is intended to compensate for a wide range of moderate to severe hearing losses including flat, ski-slope and reverse slope losses. It features digital control of a highly flexible digital signal processor |
| | Up to 32 digitally adjustable parameters and two listening situations (memories) are accessible to shape and modify the instrument's response, depending on the model configuration. These include: Channel Delineation, Curvilinear Compression, Linear Compression, Syllabic Compression, Dual Compression, Voice Activity Detection System, Channel Gain, Cross Channel Shaping, Interchannel coupling, Twin Microphone System/Direction Mic, Low level Squelch, |
| | Second Program. |
| Assembly: | Assembled from standard components that are widely utilized by other hearing aid manufacturers. |
| Technical Characteristics: | Technical specifications comply with s3.22-1987 ANSI Specifications |
| Fit: | The frequency response of the product is dictated by the individual Audiogram from each client and the settings of the programmable controls. |
| Controls: | User adjustable controls may be found on the Behind-the-Ear model which include a Microphone- Telecoil-Off (M-T-O) switch, and a momentary push-button switch to change between the two stored memories. Depending on the specific configuration of the instrument as ordered by the hearing instrument professional, some of these user controls may not be present. With the custom products, PRISMA comes standard with no user adjustable controls unless specifically requested by the hearing instrument professional, in which case a push button switch and/or directional microphone is available. |
| Power: | Standard Hearing Aid Batteries: 5A,10A, 13, 312 and 675 |
A User's manual and General Information for Hearing Aid Users Guide is supplied with each hearing aid.

Dear Mr. Bea:
We have reviewed your Section 510(k) notification of intent to market the device referenced above 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 Aproval), 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 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 clectromagnetic interference, such as "compatible with digital cellular telephones", and that data supporting such claims is necessary.
