Tondi BTE Hearing Aid, Models U-2011, U-214, U-03, KA-02, KA-03, KA-UBA, KA-01, KA-04, KA-04A, KA-05
I am sorry, but based on the provided documents, there is no information about acceptance criteria or a study that proves the device meets those criteria.
The documents are a 510(k) premarket notification letter from the FDA to National Hearing Aid Distributors regarding their "Tondi BTE Hearing Aids" (K971296). These documents primarily focus on the FDA's determination of substantial equivalence to previously marketed devices and the device's indications for use.
The letter explicitly states: "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... to devices marketed in interstate commerce prior to May 28, 1976..." This indicates that the device's acceptance for marketing is based on its similarity to existing, legally marketed devices, rather than a specific performance study with defined acceptance criteria.
The subsequent pages (2-6 of 6) detail the "Indications For Use" for various models of the Tondi BTE Hearing Aid, outlining the categories of hearing loss (severity, configuration, and other factors) for which the device is intended. This is about defining the scope of the device's application, not about establishing performance metrics against acceptance criteria.
Therefore, I cannot provide the requested information as it is not present in the given text.

な Dear Mr. Menezes:
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 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 Good Manufacturing Practice for Medical Devices: General (GMP) regulation (21 CFR Part 820) and that, through periodic GMP 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 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 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.

If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Office of Compliance at (301) 594-4613. Additionally, for questions on the promotion and advertising of your device, please contact the Office of Compliance at (301) 594-4639. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR 807.97). Other general information on your responsibilities under the Act may be obtained from the Division of Small Manufacturers Assistance at its toll-free number (800) 638-2041 or at (301) 443-6597 or at its Internet address ......... a ----"http://www.fda.gov/cdrh/dsmamain.html":
