A Damage To The Inner Ear Can Result In Sensorineural Hearing Loss    

The Damaged Cells Prevent Hearing Certain Frequencies    

One of the causes of hearing loss is related to the electrical signals between the inner ear and the brain. The inner ear includes the cochlea, which is a structure similar to a snail’s shell, and the vestibular system, which consists of three rings on different axes, that control balance. Inside the cochlea, there are nerve cells connected to hairs, which are activated by certain sound frequencies, and convert them to electrical impulses. When these nerve cells in the cochlea are damaged, the condition is called sensorineural hearing loss. Damage can occur by trauma, ototoxic medication (a medication with side effects that affect the inner ear), autoimmune disease, genetics, heart disease, and diabetes. The usual treatment is to make sounds louder via hearing aids. A diagnostic will reveal what frequencies must be amplified, and the hearing aid will be tuned to amplify these frequencies. Another consequence of hearing loss is the lack of stimulus in the brain since it cannot receive certain frequencies. A hearing aid will enhance the frequencies corresponding to the damaged hair cells and nerve cells, providing proper brain stimulation. Click here for more info.
