Feedback This basically is a phenomenon where the amplified sound re-enters the hearing aid and is re-amplified. Typically, it sounds like a high pitched whistle, the loudness and pitch of which can vary. Feedback is often an integral part of life with hearing aids. For instance Instruments may whistle if they are turned on whilst inserting them into the ear, putting on or removing clothing over your head, using the telephone, laying your head down or by hugging another person. So when is feedback acceptable? If you are wearing your hearing instrument and place your hand close to it, you may experience feedback. Although this can be quite alarming at first, it is normal. However, if feedback occurs after your hearing aids have been placed in your ear(s) correctly as a result of chewing, or normal head movement this would be considered to be unacceptable. This can generally be corrected by adjustment to the hearing instrument by your Hearing Aid Audiologist. |
