Whistling Hearing Aids

Whistling Hearing Aids – Hearing Specialist

Whistling is a problem that some people experience with their hearing aids. It is called ‘FEEDBACK’ and can be disconcerting to the hearing aid wearer and those around them……….

Feedback is caused by amplified sounds from the hearing aid leaking out from inside the ear through tiny spaces between the earmould or hearing aid and the ear, and then going back into the microphone of the hearing aid.

Generally speaking, a hearing aid will whistle when it is held in your hand or if you turn it on before placing in your ear, or if you cup your hand over your ear whilst it is in your ear. Once the hearing aid or mould is sitting in your ear properly and at the correct volume setting, it should not whistle.

The following are some of the causes of feedback (whistling), and what can be done to stop it:-

EAR WAX

Excessive wax build-up in the ear can be a cause of the feedback as it blocks the sound from travelling down the ear canal to the inner ear.

Solution

* Ask your Doctor or Clinician to check your canals for wax build up. If there is too much wax it will have to be removed by a Doctor.

DAMAGED HEARING AID SHELL, EAR MOULD OR SPLIT TUBING

* The plastic tubing for behind the ear hearing aids can become brittle with age and split, allowing sound to leak out. The hearing aid shell or ear mould can also crack also causing leakage of amplified sound.

Solution

* Contact The Hearing Aid Centre to arrange for repair, re-tubing or new ear mould.

EAR MOULD OR HEARING AID NOT SITTING IN EAR PROPERLY

An ear mould or hearing aid not inserted into the ear correctly can also cause feedback. Sometimes the mould or aid can work its’ way loose due to ear and jaw movements, breaking the ‘seal’ between the device and the ear – leaving space for the sound to leak out.

Solution

* Make sure that your hearing aid and earmould are correctly positioned in the ear. Check in the mirror or ask family or a friend to make sure that it is inserted properly.

* if you have a mould that is difficult to insert you may find that using a lubricant will make it slide in more easily. If you have ear infections for skin problems, however, it is recommended you check with your Doctor first before using a lubricant in your ears.

* If you are having continual difficulty putting the earmould or hearing aid in your ear, contact The Hearing Aid Centre for assistance.

EAR MOULD MATERIAL

Soft materials used with powerful behind the ear hearing aids can shrink and deteriorate more quickly than the hard materials commonly used with lower power hearing aids and will need to be replaced more frequently.

Solution

* If your earmould has discoloured and/or hardened you will need a new ear mould. Contact The Hearing Aid Centre for an appointment.

POOR FITTING EAR MOULD OR HEARING AID

A change (loss or gain) of body weight can affect the shape of the ear canal causing a poor ‘fit’ of the mould or hearing aid.

Solution

* Contact The Hearing Aid Centre for an appointment for a new impression of your ear to be made.

INCREASING THE VOLUME ABOVE THE RECOMMENDED LEVELS

When you are fitted with your hearing aid, it is usually set at a mid level for your normal listening needs, so that you can increase the volume if required. If you find that you continually have to increase the volume on the hearing aid, the aid may whistle.

Solution

* If you are routinely turning up your hearing aid past it’s original volume setting, you should contact The Hearing Aid Centre to arrange for the hearing aid to be checked. If the hearing aid is working properly, an appointment will be necessary for a new hearing test to see if your hearing has changed.

In conclusion….

If your ears are free of wax and the hearing aid is constantly whistling when inserted correctly and on your preferred volume setting, the best solution is to contact The Hearing Aid Centre as often a new ear mould or hearing aid re-shell will solve the problem.
