Types of Hearing Tests
A variety of tests* can be done to identify and diagnose hearing
loss. The method used depends in part on the age of the individual
along with other factors based on specific needs. If you’ve had your
hearing checked at an audiologist’s office, you’ve probably received
more than one type of test. Here are some of the main types of
hearing tests, what they measure and what you can expect if you’re
getting one.

Standard Hearing Screening, also known as Pure-Tone Testing –
This hearing test determines the faintest tones a person can hear at
selected pitches, or frequencies, from low to high. During this test,
earplugs or earphones are worn, so that information can be
obtained for each ear. The person taking the test will then be asked
to respond when they hear a sound. The audiologist may have you
respond to the sound in a variety of ways, such as raising a finger
or hand, pressing a button, or saying “yes” to indicate that a sound

was heard. The sounds played are at different pitches and levels.
The results will be recorded on an audiogram.
Speech Testing – This is an aspect of the standard exam where
speech discrimination or word recognition is tested. This helps
confirm the pure-tone test results and it helps audiologists assess
how well a hearing aid can help. The test involves word recognition
and repeating words at a comfortable loudness level. It’s also
recorded on the audiogram.
Middle Ear Testing – This provides information on how the middle
ear is functioning. These measurements include tympanometry
(putting air pressure into the ear canal to measure the mobility of
the eardrum). This test helps detect fluid, perforation of the
eardrum or a wax blockage.
Auditory Brainstem Response (ABR) Testing – This test measures
how long it takes sound to get from your ear to the processing
areas in your brain. This can reveal if the pathways between the
brain and the inner ear are working correctly. An ABR test is
performed by placing small electrodes on the head and recording
brain wave activity in response to sound. The person being tested is
either quietly resting or asleep. A computer averages the
information for the audiologist to interpret.
Otoacoustic Emissions Testing – Otoacoustic Emissions (OAEs) are
sounds given off by the inner ear when the cochlea is stimulated by
a sound. When sound stimulates the cochlea, the outer hair cells
vibrate. The vibration produces a nearly inaudible sound that
echoes back into the outer ear. This sound can be measured by a
small probe inserted in the ear canal.
