Overcome Hearing Loss in Miami

How you hear
Hearing happens when sound waves reach the structures inside your ear, where the vibrations of the sound waves re converted into nerve signals that your brain recognizes as sound.

Your ear is made up of three major areas: the outer ear, middle ear and inner ear. Sound waves pass through the outer ear and cause the eardrum to vibrate. The eardrum and three small bones of the middle ear — the hammer, anvil and stirrup — amplify the vibrations as they travel to the inner ear. There, the vibrations pass through fluid in the cochlea, a snail-shaped structure in the inner ear.

Thousands of tiny hairs that help translate sound vibrations into electrical signals to be transmitted to your brain are attached to nerve cells in the cochlea. The vibrations of different sounds affect these tiny hairs in different ways, which in turn cause nerve cells to send different signals to your brain. That’s how you distinguish one sound from another.

What causes hearing loss
For some people, hearing loss is the result of a gradual buildup of earwax, which blocks the ear canal, prevents sound waves from passing. Earwax blockage is a cause of hearing loss among people of all ages.

In most cases, however, hearing loss results from damage to the inner ear. Aging and prolonged exposure to loud noise may cause wear and tear on the nerve cells or hairs in the cochlea that send sound signals to the brain. When these hairs or nerve cells are damaged or missing, electrical signals aren’t transmitted as well, and hearing loss occurs. Higher pitched tones may become muffled; it may become difficult to differentiate words from background noise.

Ear infection and abnormal bone growths or tumors of the outer or middle ear can cause hearing loss. A ruptured eardrum also may result in loss of hearing. Heredity can even play a part, and may make you more prone to these changes.

If you or a loved one suffers from such symptoms or you believe he or she have been affected by hearing loss, contact Dr. Joseph K Duran at the New Generation Hearing Centers in Miami.
