When the Hearing Aid is Whistling

Most of the time hearing aids perform flawlessly without giving rise to any difficulties. However, there is always the occasional instance of a hearing aid emitting a high-pitched whistle that is extremely annoying. There are a number of reasons why it should create this irritating form of feedback but there are always solutions.

Check Your Volume

Sometimes wearers are tempted to turn up the volume of their hearing aids in order to hear more distinctly. However, this often has a negative effect as many perform at their best when operated at a moderate level. The first thing to do is reduce the volume but if you still can’t hear well enough without the volume set at high, check with your audiologist to discover whether the hearing aid has developed a fault.

Hearing Aid Covers

Sometimes the cover can become loose due to wear and tear. Even exercise can cause a minor short circuit causing the hearing aid to whistle. One solution is to remove the cover and turn down the volume until you can have the hearing aid checked.

Ear Wax

Even hearing aid wearers still suffer problems with excess ear wax, known as cerumen. There can be an accumulation that blocks the ventilation hole in the hearing aid prompting it to whistle. For best results visit your audiologist to have your ears professionally cleaned.

Faulty Tube

If the hearing aid is the type that has a slim tube leading into the ear, it can over time react to the condensation that forms inside causing it to deteriorate. The tubing will gradually shrink and become brittle. Once the flexibility in the tube has disappeared it is time to have a replacement fitted.

Ill Fitting

There are always miniscule changes in the tissues of the ear which can be exacerbated by instances such as an increase or loss in weight. Over the years, hearing aids might need several adjustments to keep them working correctly. If a hearing aid no longer fits snugly it can cause it to emit a high pitched whistle. Always have regular check ups with your audiologist to ensure that your hearing aids are still fitting correctly.

Other Causes

Even during fitting it can emit a whistling noise although there are models that incorporate a delay mechanism which should allow for activating the power supply. Sometimes being near to electrical equipment or even other people such as when hugging, can create a brief whistling tone.

How to be Free of Whistling

It’s wise to regularly update your hearing aids to take advantage of the new developments that are being introduced. If you suffer regularly from irritating whistling you might benefit from one of the sophisticated Completely in Canal (CIC) models which are customised to sit deeper into the ear canal. They can completely eradicate feedback through the use of advanced digital technology. To discover whether this reliable non-whistling style is suitable for you to wear consult an experienced audiologist such as Hear4U.
