Section 246-828-090 - Standards for equipment calibration

(1) All electronic equipment utilized by licensees for the determination of audiometric thresholds for pure tones and for speech must conform to all current standards of the American National Standards Institute (ANSI). Licensees must confirm that all such audiometric equipment has been evaluated electrically and acoustically at least once each year, adjusted or repaired if necessary, and that conformity with ANSI standards was determined at that time. Licensees must maintain calibration records permanently and make the records available for inspection by the department at any time. No licensee may certify the calibration of his or her own equipment unless authorized to do so by the department. In addition, all licensees must use routine procedures for the daily inspection of audiometric equipment, or prior to use if used less often than on a daily basis, to generally determine that it is in normal working order.

(2)Hearing instruments, assistive listening devices, and electronic equipment used for assessment or monitoring of auditory and vestibular function must be maintained according to manufacturer's specifications.

(3)All instrumental technology used to diagnose or treat disorders of communication, swallowing, and hearing must be maintained in proper working order and be properly calibrated according to manufacturer's specifications.
