What causes tinnitus? Scientists and health experts don't know the exact physical cause of tinnitus, but several sources are known to trigger or make it worse, including: Loud noises and hearing loss – Exposure to loud noises can destroy the non-regenerative cilia (tiny hairs) in the cochlea, causing permanent tinnitus and/or hearing loss. Aging – As you age, those same cilia gradually deteriorate, which can lead to tinnitus and/or hearing loss. Ototoxic medications – Some prescription medications such as antibiotics, anti-inflammatories and antidepressants are harmful to the inner ear as well as the nerve fibers connecting the cochlea to the brain. Hearing conditions – Conditions such as otosclerosis and Ménière’s disease are known to cause tinnitus. Health conditions – Tinnitus can also be a symptom of health conditions like cardiovascular disease, hypertension, stress and head injuries.
Symptoms of Hearing Loss and Levels of Hearing Loss Listen up! Don't take your ears for granted. Hearing loss is the third most common health problem in the U.S, and it can affect the quality of your life and relationships. About 48 million Americans have lost some hearing. Certain conditions, including age, illness, and genetics, may play a role in hearing loss. Modern life has added a host of ear-damaging elements to the list, including some medications and plenty of sources of loud, ongoing noise.
Learning More About Hearing Loss To understand hearing health and hearing loss, you should first understand how your ear works to capture sound and transmit it to your brain. The outer ear is designed to capture sounds and funnel them into the ear canal. The sounds enter your ear canal, where they cause vibrations in your eardrum. The eardrum has the job of transferring the sound waves from your outer ear to your inner ear. As the sound passes through the inner ear, it vibrates tiny hair cells that represent individual frequencies or pitches. If you think about the inner ear as a piano, some hairs represent the highest notes on the piano, and some represent the lowest. As the various hairs vibrate, it triggers transmission of those frequencies to your brain for interpretation of what sound you have heard. Your ability to hear clearly can be impacted by certain medical conditions, genetics, accidents, prolonged exposure to loud noises, or even aging.
