(a) air conduction tests shall be conducted bilaterally in accordance with American National Standards Institute (ANSI) standard frequencies of 250-500-1000 - 2000-4000-6000 hertz. Appropriate masking shall be used.
(b) bone conduction tests shall be conducted bilaterally, if appropriate, on every patient in accordance with ANSI standards at 500-1000-2000 -4000 hertz. Appropriate masking shall be used.
(c) speech reception threshold and discrimination testing shall be conducted in a quiet environment, with appropriate masking used and measurement of user discomfort level.
(d) at the time of fitting or during the course of the trial period, the dispenser will verify and/or validate the hearing aid fitting and document the results.
(i) verification refers to generally accepted and appropriate established standards of practice to objectively analyze aided performance.
(ii) validation establishes the patient's perceived improvement.
(2) Reports of audiometric test results on the patient's audiogram for the purpose of fitting and dispensing hearing aids shall include the following information:
(a) name and age of the patient;
(b) date of the test;
(c) name and license number of the person performing the test; and
