(i) Visible congenital or traumatic deformi-

sive hearing loss within the previous 90
(iv) Acute or chronic dizziness.
(v) Unilateral hearing loss of sudden or

(Hz), 1,000 Hz, and 2,000 Hz.
(vii) Visible evidence of significant cerumen
(earwax) accumulation or a foreign
body in the ear canal.|
(viii) Pain or discomfort in the ear. Special
care should be exercised in selecting
and fitting a hearing aid whose maxi-
mum sound pressure level exceeds

ing aids with a maximum sound pressure
capability greater than 132 [db].
