6/13/2023 0 Comments Binaural hearing aidsFigure 1 shows that fewer than one-quarter of all US hearing aids fit prior to 1980 were binaural, and controversies swirled around the benefit of binaural fittings well into the late-70s. However, the road to this particular “best practice”-with probably around 85% of all of today’s fittings involving two hearing aids-was not a smooth one in the United States. Act 1: Challenges and Questions about Binaural Benefitīinaural hearing aid fittings have completely changed the hearing healthcare landscape for the better. Percentage of binaural (in red) versus monaural hearing aid fittings (in blue) from 1975 to 2016 in the United States, as reported by Hearing Instruments and Hearing Review surveys of hearing care professionals (HCPs). Essentially, it has all (okay, maybe just some!) of the key movie elements found in a science thriller: legendary hearing researchers indicating binaural aids weren’t particularly beneficial leading hearing aid specialists saying they were more legendary researchers and clinicians re-assessing the question and coming to new conclusions-all against a backdrop of finger-pointing and accusations about self-interests and profits, as well as a pivotal ruling by the Supreme Court.

This results in a better sound quality and a reduced risk of sound distortion. In fact, studies have revealed that when an individual uses two hearing aids, they require less amplification than they would require if they were only wearing one. Your selective listening ability – your ability to pay attention to one voice or sound while ignoring all others – is also improved when both hemispheres of your brain are involved. Scientists have found that when you use both sides of your brain to process sound, you see a noticeable improvement in your ability to understand speech. Then, both brain hemispheres work together to process and interpret the sounds. When sound enters your left ear, it is processed on the right side of your brain, while the sound that enters your right ear is processed on the left side of your brain. When you have one ear that’s more impaired than the other it can result in fatigue and discomfort when listening for a prolonged period of time. Binaural hearing makes it possible to identify the location of sound far more effectively. Just as covering one eye results in a loss of depth perception, the loss of hearing in one ear results in impaired sound perception. As a result, when we fit this type of patient with just one hearing aid, they typically find that they still feel “lopsided.” Therefore, it is customary to provide a patient with two hearing aids, each providing a unique degree of assistance in a manner that’s similar to the way in which you might have two different lens prescriptions in your eyeglasses. Most individuals have bilateral hearing loss – impairment on both sides. It’s relatively rare for an individual to have perfect hearing in one ear and noticeable impairment in the other ear. It’s not uncommon for these patients to ask questions such as, “Why can’t I treat my ‘bad ear’ for hearing loss? Why do I need two hearing aids?” Well, the answer to this question is actually quite simple: in most cases, the individual has hearing loss in both ears it’s simply more pronounced and noticeable on one side. Often, individuals experience hearing loss in one ear (also known as unilateral hearing loss), yet their health care professionals will recommend getting two hearing aids – one for each ear. Humans naturally have what’s known as binaural hearing, which is the ability to hear in two ears.
