Individuals often experience different levels of hearing loss in each ear.
And patients in this situation frequently ask us, “Can’t I just treat my really bad ear for hearing loss? Won’t that be improvement enough?”
While we at Denver Audiology sometimes see patients with hearing loss in only one ear (also known as unilateral hearing loss), typically the factors that led to the impairment have affected both ears — just to a different degree. In this relatively common situation, we find that fitting just one hearing aid usually fails to provide a satisfying sound experience for the wearer.
Hearing well with both ears not only takes advantage of our ears’ critical ability to identify the location of sound (a surprisingly important component of our ability to listen and to focus on sound effectively), it also helps make speech easier to understand in the presence of noise and helps reduce the fatigue and confusion brought on by difficult listening environments.

Profound Unilateral Hearing Loss
In less common cases in which there is a total hearing loss in one ear (also known as profound unilateral hearing loss or single-sided deafness), there are medical therapies that may help to re-create some of the effects of binaural hearing. These include bone-conduction systems (also known as bone-anchored hearing aids, or BAHA devices) that can help transmit vibrations from the nonhearing ear to the functioning ear. Also, CROS (contralateral routing of sound) hearing aids are available that use a microphone in the nonhearing ear to transmit the sound to the hearing hear.

Frequently Asked Questions
Hearing loss is a puzzle that our professionals love to solve, and it is based on your individual experiences, lifestyle, and severity of impairment. There is no one-size-fits-all treatment method for hearing loss — it’s based on the sounds that you can’t hear, which vary greatly, and the sounds that you want to be able to hear. A quality hearing system from a reputable manufacturer isn’t effective until an experienced, qualified hearing care professional programs the technology properly based on your unique hearing needs.
Research has established a relationship between hearing loss and dementia. There is strong evidence that hearing loss accelerates brain-tissue atrophy, particularly in areas of the brain that auditory nerves would stimulate but can’t because they aren’t receiving a signal (due to a hearing loss). These areas of the brain are also related to memory and speech. Individuals with a mild hearing loss are three times as likely to fall down than those without, and the likelihood of falls increases as degree of hearing loss increases. Hearing loss has also been linked to diabetes, cardiovascular disease, sickle-cell anemia, and other circulatory conditions.
Since hearing loss is cumulative, hearing loss begins as an infant and continues throughout life. Most individuals don’t begin to experience symptoms until their late 20s or early 30s, and by age 45 a yearly hearing check becomes of greater importance. One-third of people beyond the age of 65 have some degree of hearing loss, however mild or severe, and that share of the elderly population increases as they age.
Unfortunately, many forms of hearing loss are permanent because there is no cure. Treatment methods that feature amplification fit to your specific hearing loss by a hearing care professional typically have the highest user satisfaction for improved hearing and improved quality of life.
Protecting your hearing from noise levels greater than 85 decibels at work and during leisure activities will greatly reduce your chances of noise-induced hearing loss. Many manufacturing jobs require hearing protection in loud environments, but hearing protection is also recommended while ATV riding, hunting, attending concerts and sporting events, and playing music — all situations where your hearing is vulnerable.
Though it is difficult to say what genetic factors predispose individuals to hearing loss, there seems to be a connection. Some genetic disorders present at birth cause a hearing loss, but in the absence of a disease, hearing loss can still have a basis in your genetics.
See your physician immediately; sudden hearing loss is considered a medical emergency. Sudden hearing loss typically resolves on its own within two weeks, but it might not — meaning your hearing might be gone for good. Seeking medical assistance within 72 hours of the onset of sudden hearing loss greatly improves the chances that your hearing will recover.
