Section 250. Testing procedures

It shall be the duty of each licensee and holder of a temporary permit engaged in the fitting and sale of hearing aids to use appropriate testing procedures for each hearing aid fitting. All tests and case history information must be retained in the records of the specialist. The established requirements shall be:

1. Air Conduction Tests A.N.S.I. standard frequencies of 500-1000-2000-4000 Hertz. Intermediate frequencies shall be tested if the threshold difference between octaves exceeds 15dB. Appropriate masking must be used if the difference between the two ears is 40 dB or more at any one frequency.

2. Bone Conduction Tests are to be made on every client--A.N.S.I. standards at 500-1000-2000-4000 Hertz. Proper masking is to be applied if the air conduction and bone conduction readings for the test ear at any one frequency differ by 15 dB or if lateralization occurs.

3. Speech testings shall be made before fittings and shall be recorded with type of test, method of presentation and the test results.

4. The specialist shall check for the following conditions and, if they are found to exist, shall refer the client to a licensed physician unless the client can show that his present condition is under treatment or has been treated:

a. Visible congenital or traumatic deformity of the ear.

b. History of active drainage from the ear within the previous 90 days.

c. History of sudden or rapidly progressive hearing loss within the previous 90 days.

d. Acute or chronic dizziness.

e. Unilateral hearing loss.

f. Audiometric air bone gap equal to or greater than 15 dB at 500 Hertz, 1000 Hertz, and 2000 Hertz.

g. Visible evidence or significant cerumen accumulation or a foreign body in the ear canal.

h. Tinnitus as a primary symptom.

i. Pain or discomfort in the ear.

5. All tests shall have been conducted no more than six months prior to the fitting.

6. Post-fitting testing shall be made and recorded with type of test, method of presentation and the test results.
