(1) The following minimal procedures shall be used in the fitting and selling of prescription hearing aids:(a) Pure tone audiometric testing by air and bone to determine the type and degree of hearing deficiency.
(b) Effective masking when indicated.
(c) Appropriate testing to determine speech reception thresholds, speech discrimination scores, the most comfortable listening levels, uncomfortable loudness levels, and the selection of the best fitting arrangement for maximum hearing aid benefit.
(2) The following equipment shall be used:(a) A wide range audiometer that meets the specifications of the American National Standards Institute for diagnostic audiometers.
(b) A speech audiometer or a master hearing aid in order to determine the most comfortable listening level and speech discrimination.
(3) A final fitting ensuring physical and operational comfort of the prescription hearing aid shall be made.
(4) The following medical clearance shall be obtained: If, upon inspection of the ear canal with an otoscope in the common procedure of a prescription hearing aid fitter and upon interrogation of the client, there is any recent history of infection or any observable anomaly, the client must be instructed to see a physician, and a prescription hearing aid may not be fitted until medical clearance is obtained for the condition noted. If, upon return, the condition noted is no longer observable and the client signs a medical waiver, a prescription hearing aid may be fitted. Any person with a significant difference between bone conduction hearing and air conduction hearing must be informed of the possibility of medical correction.
(5)(a) A prescription hearing aid establishment must have available, or have access to, a selection of prescription hearing aid models, hearing aid supplies, and services complete enough to accommodate the various needs of the prescription hearing aid wearers.
(b) At the time of the initial examination for fitting and sale of a prescription hearing aid, the attending hearing aid specialist shall notify the prospective purchaser or client of the benefits of telecoil, “t” coil, or “t” switch technology, including increased access to telephones and noninvasive access to assistive listening systems required under the Americans with Disabilities Act of 1990.
(6) Each audiometric test conducted by a licensee or authorized trainee in the fitting and selling of prescription hearing aids must be made in a testing room that has been certified by the department, or by an agent approved by the department, not to exceed the following sound pressure levels at the specified frequencies: 250Hz-40dB, 500Hz-40dB, 750Hz-40dB, 1000Hz-40dB, 1500Hz-42dB, 2000Hz-47dB, 3000Hz-52dB, 4000Hz-57dB, 6000Hz-62dB, and 8000Hz-67dB. An exception to this requirement shall be made in the case of a client who, after being provided written notice of the benefits and advantages of having the test conducted in a certified testing room, requests that the test be conducted in a place other than the licensee’s certified testing room. Such request must be documented by a waiver which includes the written notice and is signed by the licensee and the client before the testing. The waiver must be executed on a form provided by the department. The executed waiver must be attached to the client’s copy of the contract, and a copy of the executed waiver must be retained in the licensee’s file.
(7) The board may prescribe the minimum procedures and equipment which must be used in the conducting of hearing assessments, and for the fitting and selling of prescription hearing aids, including equipment that will measure the prescription hearing aid’s response curves to ensure that they meet the manufacturer’s specifications. These procedures and equipment may differ from those provided in this section in order to take full advantage of devices and equipment which may hereafter become available and which are demonstrated to be of greater efficiency and accuracy. The board shall adopt and enforce rules necessary to implement this subsection and subsection (6).
(8) Any duly authorized officer or employee of the department may make such inspections and investigations as necessary to determine the state of compliance with this section and the applicable rules and may enter the premises of a licensee and inspect the records of same upon reasonable belief that a violation of this law is being or has been committed or that the licensee has failed or is failing to comply with this part.
(9) A licensed hearing aid specialist may service, market, sell, dispense, provide customer support for, and distribute prescription and over-the-counter hearing aids.
