The largest hurdle for the hearing impaired can be acceptance of the problem.

If you are having difficulty with your hearing, experts advise that you see a physician to make sure no medication is causing the problem, that neither medication nor surgery can relieve it and to determine if you can be helped with a hearing aid. Your doctor can refer you to a specialist to fit you with the appropriate aid.

Hearing aids are miniature amplification systems. They usually consist of a microphone, which picks up sound waves and converts them into electrical signals; an amplifier that increases the strength of the signal; a battery that powers the aid; a receiver that changes the electrical signal back to sound waves, and a specially-fitted ear mold that connects the receiver to the ear canal.

The four basic types:

* In-the-ear: Fits directly into the ear, with a section extending into the ear canal. Most suitable for mild hearing loss.

* Behind-the-ear: Curved unit rests behind the ear, connected to the ear mold by a short plastic tube. Effective for mild to severe loss.

* Eye-glass: Built into the temple of glasses.

* Body aid: A case carried on the body, connected to the ear mold by a cord. The most powerful amplification, but rather cumbersome. Becoming outmoded with the development of more sophisticated amplification techniques.
