![]() ![]() During childhood, another 2 to 3/1000 children acquire moderate to severe hearing loss. ![]() Two to 3 times as many are born with lesser hearing loss. About 1/800 to 1/1000 neonates are born with severe to profound hearing loss. More than 10% of people in the US have some degree of hearing loss that compromises their daily communication, making it the most common sensory disorder. More than 10% of people in the US have some degree of hearing loss that compromises their. Keep in mind that if you want to take advantage of wireless features, both hearing aids must be wireless.Worldwide, about half a billion people (almost 8% of the world's population) have hearing loss ( 1 General reference Worldwide, about half a billion people (almost 8% of the world's population) have hearing loss ( 1). If not, you should be able to return one of them. Under this arrangement, you would be fitted with two hearing aids and then, over a period of several weeks, you would decide whether you hear better with two. If your audiologist recommends two hearing aids and you’re not sure that you want or need two, ask if you can use two on a trial basis. That’s because soft tones sound louder when the brain is receiving signals from two ears rather than one. One undisputed advantage of wearing two hearing aids is that you can set them at a lower volume than if you wear just one. There’s no proof that the auditory nerves actually deteriorate from inadequate stimulation, but research shows that other parts of the nervous system-most notably the brain-do suffer from lack of use. Some hearing experts think that wearing two hearing aids may even help conserve hearing in the weaker ear by keeping the auditory nerve stimulated with adequately amplified sound. This means they are able to maintain localization cues better than hearing aids working independently of each other. Wearing wireless hearing aids in both ears enhances the binaural hearing process because the hearing aids communicate with each other and transfer data back and forth, rather than working independently to process sound. But the brain can’t locate a sound as well if sound signals are always louder through one ear. The brain normally does this by comparing the qualities of the sound signals that come through each ear-their relative loudness, their frequencies, and the time it takes them to travel through the ears. It may also be harder for the brain to identify the location of particular sounds if you’re wearing a single hearing aid. As a result, it’s harder for your brain to give it preferential status. But if you’re wearing just one hearing aid and someone talks into your unaided ear in a noisy room, the voice may sound softer than the background noise. The brain can pick out the important signals, like voices, when they’re louder than the background noise. With normal hearing, sound signals from both ears are comparable in strength. When you have two hearing aids, you can take better advantage of the way the brain processes sound through what’s known as binaural hearing. (You may have one ear that’s better than the other, but chances are both will be in the same ballpark.) In that case, research and experience suggest that you’ll ultimately be more satisfied with two hearing aids. But most people have hearing loss in both ears, especially if the loss is age-related. If you have hearing loss in only one ear and normal or nearly normal hearing in the other, then one hearing aid is all you need. Chances are that your first question will be, “Is it normal to get two hearing aids?” And then, “Do I really need two?” If you’re like most people with hearing loss, you’ll probably find that it takes time to accept the idea that you need a hearing aid, and you may be unhappy when your audiologist recommends that you get not one, but two. ![]()
