Often, when hearing aid users place a telephone receiver to their ear, their hearing aid makes an unpleasant whistling noise. A telecoil option, added to a hearing aid, uses the electromagnetic energy produced by the telephone and eliminates the annoying feedback. The hearing aid will have a switch allowing the user to choose between the standard microphone mode and telephone compatible mode. Ask your audiologist to explain the features of your hearing aid to you.
