Hearing Loss
Hearing loss is a widespread condition that affects approximately 36 million American adults. While it affects people of all ages, it is most common in older people, with 1/3 of the population experiencing hearing impairment by the age of 65.
The symptoms of hearing loss aren’t always obvious to those affected. It often comes on so gradually that subtle changes in hearing are difficult to detect. Signs include speech that sounds muffled, frequently asking a speaker to repeat what was said, having trouble with conversations in the presence of background noise, and turning up the volume on the television or radio.
In addition to loss of hearing due to natural aging (presbycusis), other causes may include noise exposure, medical conditions (e.g. Meniere’s disease and otosclerosis), ear infections, excessive buildup of earwax, trauma, or genetics.
There are three main types of hearing loss: conductive, sensorineural, and mixed. Conductive hearing loss is a problem of sound transmission and involves problems of the outer or middle ear and is frequently treatable. It can be caused by aging, ear infections, earwax, trauma or growths. Surgery is often successful in restoring hearing. Sensorineural hearing loss is the result of nerve damage to the inner ear caused by noise exposure, viruses and infections, and hereditary factors. Most types of sensorineural hearing loss respond very well to hearing aids. Mixed hearing loss is a combination of conductive and sensorineural hearing loss.
Hearing loss due to genetics and aging is not preventable so it is important to take measures to protect your hearing when possible. Environmental, industrial, and recreational noise exposure can be mitigated through the use of proper hearing protection.
