Hearing Aids

A hearing aid is an electronic, battery-operated device that amplifies and changes sound to allow for improved communication. Hearing aids receive sound through a microphone, which then converts the sound waves to electrical signals. The amplifier increases the loudness of the signals and then sends the sound to the ear through a speaker.

Million’s of people world wide have a hearing impairment. Hearing loss is one of the most prevalent chronic health conditions in the United Kingdom.
On the basis of the hearing test results, the audiologist can determine whether hearing aids will help. Hearing aids are particularly useful in improving the hearing and speech comprehension of people with sensor neural hearing loss.
When choosing a hearing aid, the audiologist will consider your hearing ability, work and home activities, physical limitations, medical conditions, and cosmetic preferences. For many people, cost is also an important factor. You and your audiologist must decide whether one or two hearing aids will be best for you. Wearing two hearing aids may help balance sounds, improve your understanding of words in noisy situations, and make it easier to locate the source of sounds.

Medically, there are two major types of hearing loss. Conductive hearing loss involves the outer and middle ear. It usually results from a wax blockage, a punctured eardrum, birth defects, ear infections, or it may be genetic. Conductive hearing loss generally can be corrected surgically.
Sensor neural—or "nerve"—hearing loss involves damage to the inner ear. It can be caused by aging, prenatal and birth-related problems, viral and bacterial infections, genetics, trauma (such as a severe blow to the head), exposure to prolonged loud noises, the misuse of certain drugs, or fluid buildup or a benign tumor in the inner ear. Sensor neural hearing loss usually can't be repaired surgically; it's usually corrected with a hearing aid.
