1 in 5 Americans ages 12 and older experiences hearing loss severe enough to hinder communication. Hearing loss is the third most prevalent chronic condition in older Americans after hypertension and arthritis. About 26 million Americans between the ages of 20 and 69 have high frequency hearing loss due to exposure to loud noises at work or in leisure activities. Tinnitus is currently the #1 service-connected disability for veterans from all periods of service. When we become aware of a sound in our environment, it is the result of a remarkable sequence of events. The most susceptible and common parts to break down are the microscopic stereocilia, the thousands of tiny hair cells that detect and send sound impulses to the brain.


When they become injured, diseased, or die naturally, the result is sensorineural hearing loss.
When the microscopic hair cells in your cochlea are damaged, they will not send complete signals to your brain, causing you to be unable to understand the consonants within words. Wearing only one device when you need two is like asking your eye doctor to correct your vision by only wearing a lens in one side of your glasses when both eyes have vision problems: no matter how different they may be in loss. Research suggests that having untreated hearing loss causes the hearing nerve to potentially lose more hearing or cause your hearing to become more distorted, something that can never be corrected.
Keeping sound flowing to your brain through the auditory nerve will lead to better overall understanding in the long run and can prevent further hearing loss complications. Outer Ear: Sound travels through the pinna (external ear) and down the ear canal, striking the eardrum and causing it to vibrate.


Middle Ear: Vibrations from the eardrum cause the ossicles to vibrate (the three smallest bones in the human body) which, in turn, creates movement of the tiny hair cells (stereocilia) in the inner ear. Inner Ear:  The movement of the hair cells sends electrical impulses through the auditory nerve to the hearing center of the brain, which translates them to sounds the brain can recognize. This is the most common type of permanent hearing loss, and usually cannot be corrected medically or surgically.
