It is now the third most common form of physical injury after arthritis and heart disease, and hearing loss affects nearly 50 million Americans. This accounts for about 20% of the US population or one in every five people. Although in some cases it causes congenital problems, most people gradually lose their hearing as they get older. According to the National Institutes of Health [NIH], 47% of adults aged 75 and older have hearing impairment. The good news is that this situation can usually be managed with a hearing aid.
what are these?
These electronic devices are small enough to be placed inside or behind the ear to make the sound louder, allowing the user to hear more clearly in most environments. AIDS actually did not improve the auditory performance, but only amplified the voice. Most include microphones, amplifiers and receivers that deliver enhanced sound into the ear. A battery is usually required to power the device's electronic devices.
Who uses them?
As we mentioned, about one in five people have a certain level of hearing impairment, but not everyone can benefit from aid. For example, those with conductive hearing loss have structural problems that can only be corrected by surgery or medical treatment. Hearing aids are most effective for people with certain damage to the inner ear or auditory nerve. Known as sensorineural loss, usually caused by aging, noise damage or disease. The only bright spot is that this problem usually does not make a person completely unable to hear their hearing.
Finally, about 8 million Americans wear hearing aids. This may look like a lot of people, but it's just a small fraction of the amount that can benefit from their use. According to audiologists, only one in five people should wear the device. why is it like this? There are many reasons, but the lack of information is primarily a responsibility. With this in mind, let's take a moment to discuss the two types of helper tools and how to use them.
analog
For people with mild to moderate hearing loss, a simulation model may be the best choice. These devices are inexpensive and easy to adjust, converting sound waves into electrical signals, which are then amplified and transmitted to the ear.
digital
Digital devices are more versatile than analog versions, and can convert, amplify, and transmit sound waves from digital codes to the ear. Because the numeric code contains information about loudness, direction, and pitch, it's easier to adjust them to the user's needs. As you might expect, these complex aids are usually more expensive than the basic model. But like everything else, you get the price you pay. All patients with moderate to severe hearing loss should strongly consider the digital simulation version.
Hearing aids are the most effective way to treat long-term hearing impairment in most patients.
