The primary function of your ears is to detect and transmit sounds to your brain. However, many complications can cause this sense to become impaired or even lost completely. We treat all types of hearing impairment as an Ear Nose & Throat Doctor. at The Hearing Doctors ENT Associates of South Florida we have found that some of these cases were potentially preventable, others were not.

Our hope in writing this piece is that with a better understanding of the ear’s anatomy and the causes of hearing impairment, we can help people avoid these issues. To accomplish this, we believe it’s important to have an understanding of the various parts of the outer, middle, and inner ear.

Parts of the Outer Ear

The primary parts of the outer ear include:

  1. Outer layer of the eardrum (tympanic membrane)

Your eardrum is a membrane located at the end of your auditory canal. It is in the beginning of your middle ear. It is exceedingly sensitive; prolonged exposure to loud noises can cause conductive hearing loss.

2. Auditory Canal

The auditory canal, commonly known as the ear canal, has a slight curve to protect the eardrum. Build-up of earwax in your auditory canal also prevents the build-up of foreign material like dust, dirt, and small insects. The ear canal not only protects the eardrum; it’s also a kind of hearing aid. Your auditory canal amplifies lower frequencies emitted by the human voice, making it easier to understand and hear an entire conversation.

3. Middle Ear

Some of the crucial parts of the middle ear are the:

4. Ossicles

The ossicles are three tiny, attached bones known as the malleus(hammer), the incus (anvil), and the stapes(stirrup). The stapes happens to be the smallest bone in the body.

5. Tympanic Cavity

The tympanic cavity surrounds the ossicles. Infections in the middle ear can cause certain types of hearing impairments if they interfere with the movement of the ossicles or the eardum.

6. Inner Ear

The primary parts of the inner ear are the:


The cochlea is one of the most important parts of your ear; this spiral-shaped organ transforms sounds into the signals that are sent to your brain. The cochlea is also very sensitive, and susceptible to sensorineural (nerve-related) hearing impairment.

Oval Window

This window connects the inner and middle ear.

Semicircular Ducts

These ducts, attached to nerves and the cochlea, are filled with fluid. They send information to your brain to regulate your balance and the position of your head.

Auditory Tube

Your auditory tube drains fluid from your middle ear into your throat, just behind your nose.
