How We Hear

How We Hear

Outer Ear

Sound waves travel through the air. These sound waves are collected by the outer ear and passed through the ear canal towards the ear drum.

Middle Ear.

The vibration of the sound waves cause the eardrum to move in a back and forth motion. There are three small bones attached to the eardrum which transfer the vibration to the inner ear. This mechanism functions in a very similar manner to a lever.

Inner Ear

Three small bones are attached to a spiral cavity of the inner ear called the cochlea. When sound enters this cavity, a wave is created in the fluid that then stimulates tiny hair cells. The hair cells convert this wave into an electrical impulse or signal that travels to the brain via the auditory nerve.

The brain

Once the electrical impluse reaches the brain, it is decoded by the temporal lobe located on the bottom of the brain near your temples.

What You Should Know

mom-daughterNearly 30 million Americans have impaired hearing,

approximately 10% of all people in the United States. Hearing loss is one of the most prevalent chronic health conditions in the US, affecting people of all ages. Hearing loss affects approximately 17 in 1,000 children under age 18. In addition, the incidence of hearing loss increases with age: approximately 1/3 of people over the age of 65 have hearing loss. Half of those over age 75 have a significant hearing loss. Prolonged hearing loss can result in auditory deprivation, a condition related to an atrophied hearing nerve.

Causes of Hearing Loss

Hearing loss can have several causes:
– A conductive loss is caused by something that stops sounds from getting through the external or middle ear.
– A sensorineural loss (or nerve type loss) occur when there is a problem in the way the inner ear or hearing nerve works.
– A mixed hearing loss includes both a conductive and a sensorineural hearing loss.

Diagnosis:

Before hearing loss can be treated the cause must be diagnosed. A variety of tests are used to diagnose hearing problems.

Audiograms – Used to measure how well a person hears. This test is performed in a sound-proof room using an audiometer and earphones.
Tympanomerty – Assesses the status of the eardrum and middle ear.
Otoacoustic Emission Testing (OAE) – Provides a measure of cochlear (inner ear) hair cell function.
– Auditory Brainstem Response or Brainstem Auditory-Evoked Response (BAER) – A useful clinical tool to help detect, localize and monitor auditory and neurotologic deficits as well as estimate hearing in difficult to test patients.

What our patients are saying…

I have worn hearing aids for as long as I can remember.  The last pair of hearing aids I bought were from Costco.  I had all kinds of problems with the fit and there were a lot of feedback issues with my hearing aids.   I searched around and found Focus Hearing.  Even though I bought the hearing aids from another company, Michael was able to make them work for me…the way they are supposed to work. As long as I live in KC, I’ll never go anywhere else. This is how it should be.  Michael spent nearly 2 hours with me adjusting and making sure my hearing aids were comfortable.  Now, I barely know I’m wearing them.  This is personal service like it should be.   Well done.
