Hearing loss is not in the fitting range
•
of the hearing aid (i.e. gain, frequency
response)
Acute tinnitus
•
Deformity of the ear (i.e. closed ear canal;
•
absence of the auricle)
Neural hearing loss (retro-cochlear
•
pathologies such as absent/non-viable
auditory nerve)
The primary criteria for the referral of a patient
for a medical or other specialist opinion and / or
treatment are as follows:
Visible congenital or traumatic deformity
•
of the ear;
History of active drainage from the ear in
•
the previous 90 days;
History of sudden or rapidly progressive
•
hearing loss in one or both ears within the
previous 90 days;

•

Audiometric air-bone gap equal to or
•
greater than 15 dB at 500 Hz, 1000 Hz and
2000 Hz;
Visible evidence of significant cerumen
•
accumulation or a foreign body in the ear
canal;
Pain or discomfort in the ear;
•
Abnormal appearance of the eardrum and
•
ear canal such as:
- Inflammation of the external
auditory canal;
- Perforated eardrum;
- Other abnormalities which the HCP
believes are of medical concern
Special care should be exercised in selecting
and fitting a hearing aid whose maximum
sound pressure level exceeds 132 decibels
(dB) because there may be risk of impairing the
remaining hearing of the hearing aid user. (This
provision is required only for those hearing aids
with a maximum sound pressure capability
greater than 132 dB).
