An Audiologist is…

A state licensed health-care professional who holds either a doctoral degree or a master’s degree in audiology from an accredited university.

Audiologists perform any of the following functions:

prescribe and fit hearing aids

assist in cochlear implant programs

perform ear or hearing-related surgical monitoring

design and implement hearing conservation programs and newborn hearing screening programs

provide hearing rehabilitation training such as

auditory training

speech reading

listening skills improvement


Want to Be an Audiologist?

Audiology is a highly recognized profession and has been ranked by


as the Second Best Career of 2015.

US News & World Report

also lists audiology in its 30 Best Careers Report Card.

Audiologists work in a variety of settings, such as:

Hospitals, clinics, private practice, ENT offices, universities, K-12 schools, government, military, and VA hospitals.



Over 36 Million Americans

Suffer from Hearing Loss!

That is over 4 times

the amount of people living in New York City!

Over 5 million children and young adults under the age of 18 suffer from

noise-induced hearing loss.


How We Hear: Outer Ear

The outermost part of the ear is called the pinna. The pinna acts like a funnel directing sound waves into the ear canal.

The sound waves then travel through the ear canal to the ear drum.

The sound waves vibrate the ear drum and those vibrations are transmitted to the middle ear.


How We Hear: Middle Ear

The middle ear is made up of the hammer, anvil, and stirrup bones.

These three bones are the smallest in the body and are collectively known as the ossicles.


The ossicles amplify and transfer the sound vibrations from the ear drum to the inner ear.





How We Hear: Inner Ear

The inner ear is made up of the

semicircular canals and the


Each part of the inner ear is very different in form and function to the human body.

semicircular canals



Inner Ear: Semicircular Canals

The semicircular canals are the portion of the ear that helps detect movement and maintain balance.

The semicircular canals are filled with fluid, and as we move, it is that fluid that allows us to detect the

movement and maintain our balance.

Inner Ear: The Cochlea

The cochlea houses the organ of Corti.

As sound vibrations move

through the cochlea, they vibrate the microscopic hair cells found within the organ of Corti.

The vibrations of these hair cells trigger the electrical impulses sent to the brain from the auditory nerve, allowing us to hear.

Types of Hearing Loss

Sensorineural Hearing Loss

Conductive Hearing Loss

Mixed Hearing Loss

The safest way to determine if you have a hearing loss is to visit your audiologist for a hearing evaluation. An audiologist can work with you to determine the best treatment option for your hearing loss.



Sensorineural Hearing Loss:

Is permanent and sometimes preventable.

Is the most common form of hearing loss.

Can affect people of all ages.

Is a high-frequency hearing loss, that can occur from aging and/or

noise exposure (noise-induced hearing loss).

Does not have any medical or surgical treatment options, in most cases.

Hearing aids are the primary treatment (an audiologist should be your primary health-care provider for testing and fitting hearing aids).

A cochlear implant may be considered for patients with severe or profound cases of this form of hearing loss.


Sensorineural Hearing Loss

Sensorineural hearing loss occurs when the microscopic hair cells within the organ of Corti are damaged.

Once the hair cells are damaged, they do not regenerate.

From David J. Lim. Functional Structure of the Organ of Corti: A Review. Hearing Research, 22 (1986) 117-146 El



Trouble hearing conversation in a noisy environment such as


Difficulty or inability to hear people talking to you without looking at


A constant buzzing or ringing in your ears (tinnitus).

Do You have

Sensorineural Hearing Loss?

High-frequency hearing loss may be difficult to

“self-diagnose” because it occurs slowly over time.

People with this form of hearing loss often can still

hear, but they cannot hear clearly.


Conductive Hearing Loss

Some causes of conductive

hearing loss are:

Blockage in the ear canal from:

Ear wax (cerumen) build-up.

A foreign object.

Fluid occupying the middle ear space, often due to an ear infection, also called otitis media.

Happens when the sound waves are not able to reach the inner ear.


Mixed Hearing Loss

Hearing loss that involves both sensorineural and conductive hearing loss components.


People with untreated hearing loss

(people with hearing loss who do not wear hearing aids)

can experience a decreased quality of life.





Poor Social Relationships


Degrees of Hearing Loss

Audiologists use general terms to characterize the degree of hearing loss.






The category of hearing loss represents the softest level of sound (decibels) you can hear at different pitches.


The Hearing Evaluation

Audiologists perform a hearing evaluation to determine the type and severity of the hearing problem.

There are three parts to a hearing evaluation:

Review of your medical and hearing history.

Visual examination of the eardrums and ear canals.

The hearing test.


The Hearing Test

An audiologist will place you in a sound booth to test your hearing at different pitches (frequency) and decibel levels.

You will be asked to listen to a series of specific sounds and indicate which ones you hear. 

The results are noted on an audiogram that your audiologist will review with you.



Protecting your hearing is just as important as protecting your eyes or teeth.

Wear hearing protection in noisy environments (marching band, concerts, sporting events, industrial classes…)

Ear plugs

Take breaks from noisy environments. Walk away from the noise and give your ears a break.

Turn down the volume on your

car stereo, cell phone,

iPod, and

home stereo.
