What are the appropriate procedures for the measurement of human hearing?
A. The procedures accepted by the board for the measurement of human hearing by licensees and trainees comprise: (1) Pure tone audiometry, including air conduction testing and bone conduction testing. (2) Speech audiometry by live voice, or recorded voice, including speech reception threshold, speech discrimination testing, and most comfortable loudness measurements and loudness discomfort levels. (3) Appropriate masking when indicated. (4) Recording and interpretation of audiograms and speech audiometry to determine proper selection and adaptation of hearing instruments.
