Whistling in hearing instruments is known as feedback.
It is caused by amplified sound leaving the ear; being picked
up again by the microphone and being re-amplified.
The following tips will help reduce the effect of feedback:
•
Lower the volume. Keep volume at a lower setting before
inserting the instrument in your ear. Or, you may prefer
to only switch the instrument on when the device is seated
on your ear.
•
Change to a larger dome or longer tubing.
•
Ensure the ear canal is clear of wax or debris.
•
Ensure the tubing/dome are not broken/torn or blocked.
Dealing with
whistling or
feedback
•
Keep the hearing instrument clean and dry.
•
Please use a soft cloth to clean and remove any body oil or
moisture from the shell of the hearing instrument. If the hearing
device is often in a moist environment or subject to a lot of
perspiration it is recommended to put the hearing instruments
that are turned off into a ‘dry aid box’ at least once a week.
Hearing Direct stocks a number of types of dry aid boxes.
•
Do not use water or other fluids to clean the hearing instruments.
•
Always take care in handling the hearing instrument to prevent
it from falling onto any hard surfaces, such as the counter top,
table or floor.
•
Do not leave your hearing instrument in the direct sun or in areas
where the temperature can rise over 60°C / 140°F for extended
periods of time.
