Screening and Testing: Older Children and Adults

To diagnose an older child or adult when a hearing problem is suspected, one or more tests may be done. These tests can determine if there is a hearing problem, the type it is, and the amount of hearing loss present. If you are interested in having your hearing evaluated by a professional, contact a center near you.

Test

What happens

Pure Tone Audiometry (Audiogram)

A person sits in a soundproof room wearing earphones

A trained professional runs equipment that presents specific sounds in one ear at a time

The person being tested indicates when they can hear a sound (softest level) by pressing a button or raising their hand

A visual “map” shows the results (which are compared to “normal” results)

Auditory Evoked Potentials

A person listens to sounds from earphones or speakers

Equipment records the brain’s neural response from electrodes taped to the head

Test helps find cause and location of hearing problems

Tympanometry

Tests how the eardrum moves using air blown into the canal

"Sees" middle ear problems (like fluid behind the eardrum)

Otoacoustic Emissions(OAE)

Tests inaudible sounds emitted by the cochlea when the cochlea is stimulated by sound

These sounds can me measured with a small probe inserted into the outer ear canal



 
   

Hearing Loss

For hearing loss, refers to less than average ability to hear and understand sounds due to one or more parts of the hearing system not working properly.

Hearing Loss

For hearing loss, refers to problems hearing in both ears, not just one.

Hearing Loss

For hearing loss, refers to problems hearing in one, but not both ears

Mild Hearing Loss

People with mild hearing loss have some difficulty following speech, mainly in noisy situations; quietest sounds they can hear in their better ear average between 25 and 39 decibels (a standard measure of sound)

Moderate Hearing Loss

People with moderate hearing loss have difficulty following speech without a hearing aid; quietest sounds they can hear in their better ear average between 40 and 69 decibels (a standard measure of sound).

Severe Hearing Loss

People with severe hearing loss get help from powerful hearing aids, but often rely on lip-reading even when using an aid; quietest sounds they can hear in their better ear average between 70 and 89 decibels (a standard measure of sound).

Profound Hearing Loss

People with profound hearing loss mostly rely on lip-reading and/or sign language; the quietest sounds heard in their better ear average from 90 decibels or louder (a standard measure of sound).

Otosclerosis

A disease in which bone grows abnormally in the middle ear preventing structures within the ear from working properly and causing hearing loss.

Cochlea

Part of the ear that contains both the organ of hearing (the cochlea) and the organ of balance (the labyrinth).

Feedback

A high-pitched, sometime painful, whistling sound that occurs when a microphone picks up sound from a nearby speaker and replays it again and again (commonly occurs when a poorly fitting hearing aid earmold allows sound to “leak” from the speaker back into the microphone).

Assisstive Listening Devices

Electronic devices or accessories for hearing aids that provide extra help in specific listening situations (telephone, noisy backgrounds, small or large group settings, etc.).

Sensorineural Hearing Loss

Hearing loss due to failure of the auditory nerve, also called nerve deafness.

Mastoid Bone

A portion of the lower skull bone that contains the inner ear.

Rehabilitation

For individuals who previously experienced hearing and get a cochlear implant, the comprehensive training program that “re-teaches” them how to hear and interpret sounds, to recover any lost speech skills, and to properly use the cochlear implant speech processor and controls.

Habilitation

For individuals who had not previously experience hearing and get a cochlear implant, the comprehensive training program that teaches them to hear and interpret sounds, to develop or improve speech skills, and to properly use the cochlear implant speech processor and controls.

Coverage

For health insurance, coverage involves making sure a health plan or policy pays for the cochlear implant device and related professional services (for example, physician and audiology services). Usually, you go through a preauthorization process. This means getting a guarantee from the health insurance plan that they will pay for the implant and services before getting treatment.

Billing

For health insurance, billing involves the process by which health care providers charge, code, and submit their bills (in the form of a claim) to the health insurance company or plan.

Payment

For health insurance, payment involves getting the full amount allowed for services given a health plan’s limitations, allowables, deductibles, and co-payments.

Menieres

A disorder of the fluid volume of the inner ear that can cause hearing loss, dizziness/vertigo, tinnitus (ringing in the ear), and/or pressure or pain in ear.

Meningitis

a viral or bacterial infection that causes inflammation and swelling of the membranes covering the brain and spinal cord; among possible serious complications are hearing loss or deafness.

Mumps

a viral infection that causes swelling of the salivary glands; sometimes spreads to central nervous system which can result in hearing loss.

Measles

a viral infection that causes rash, fever, and cold-like symptoms; sometimes causes complications like ear or brain infections which can result in hearing loss.

Unilateral

on one side, but not the other; used to describe a type of hearing loss in which there is normal or somewhat impaired hearing in one ear and little or no hearing in the other ear.

Unilateral Hearing Loss

condition in which one ear has little or no hearing ability and the other ear has normal or close to normal hearing. Also referred to as Single Sided Deafness (SSD).

Osseointegration

the natural process of bone growing into the titanium fixtures creating a direct connection between an artificial implant and living bone.
