Modern hearing aids are an incredible resource for the hearing impaired among us in society today. Whether due to genetics, injury, or just over exposure to loud noises, millions of people suffer from hearing loss. Hearing aids today are modern technological marvels. They come in several styles ranging from big to small, but all have same basic components. All hearing aids include a micro
phone, amplifier, speaker, and battery. The microphone picks up noise, the amplifier controls volume, the speaker relays the noise to the patient's ear, and the battery gives power to the whole thing. The main styles of hearing aids are: in the ear (large), in the canal (small), completely in the canal (very small), behind the ear (larger), and behind the ear open fit (smaller). In addition, there are also digital and analog hearing aids. Digital hearing aids are more modern and provide clear sound quality that blocks out background noise better than their analog counterparts. Now there are even devices called cochlear implants that can be surgically implanted and are effective for patients with severe hearing problems. Hearing aid technology is getting better all the time, making the prospect of a world free of deafness a very real possibility.
