Modern hearing aids come packed to the brim with features like Bluetooth connectivity, the ability to stream music, noise cancellation, etc. These newer models usually come with strong features to manage this sqeeling sound well enough to never let it happen. However, older models of hearing aids, or instruments fitted incorrectly do still carry this issue.
Those of you having the experience of wearing hearing aids for a long period of time would relate to this screeching sound that used to suddenly fills your ears.
This is analogous to the same irritating effect when a microphone suddenly starts producing a shrill howling effect. Imagine this effect ringing within your ears. Of course, this is a cause of concern for many hearing aid users, and we absolutely understand that.
However, while many of us know this occurs, the actual reasons are unclear to many. We have thus compiled a guide listing why this happens and some techniques to deal with this issue.
4 Major Reasons Why Whistling Occurs in Hearing Aids
The whistling effect may lead you to conclude that your hearing aids are broken. However, that isn’t always the case. Other causes affect your hearing aids to emit an intolerable screeching sound.
Following are some of the reasons for whistling:
1. Earwax accumulation
Hearing aids carry the sound waves into your ear canal. However, when this sound is blocked, the waves tend to bounce back. This, in turn, creates a feedback loop. Excess earwax is one of the significant causes of blockage.
Thus it is imperative to keep your ear clean before opting for hearing aids. Also, it is crucial to keep the hearing aids clean because, at times, the leftover wax on the earpiece causes the same blocking effect. So before rushing to replace your hearing aids, it is advisable to keep your ears and hearing aids clean.
2. Improper fitting
In many instances, people continue to use improperly fitted hearing aids. A loosely connected hearing aid leaves a small gap between the device and the walls of the ear. This gap is more than sufficient for air and sound waves to escape through it.
This phenomenon meddles with the working of the hearing aid and causes it to emit a whistling sound. This issue will persist until and unless you find an adequately shaped hearing aid that fits your ear properly.
3. Higher level of volume
As discussed before, the major cause of whistling is the sound waves from the hearing aid bouncing back from your ears. If the hearing aid volume is higher than required, the sound waves tend to do the same. If adjusting the volume doesn’t work and whistling persists, then it is better to consult an audiologist who will help you tweak the device.
4. Miscellaneous causes
Though it may sound trivial, everyday actions can also cause the whistling effect. Even wearing hats or scarves is one reason that adds to it. In addition, excessive jaw movements while chewing, smiling and talking cause the hearing aid to send screeching feedback.
For instance, a simple act of hugging someone can be one of the causes. Thus it is better to give some time to the hearing aids to settle down after performing any of the above actions.
How To Prevent Whistling?
Based on repeated customer feedback and reviews, the current iterations of hearing aids have state-of-the-art technology that prevents whistling. It is, however, prevalent in many cases, and thus following are the ways to combat it:
- Regular cleaning of ears and the hearing aids
- Periodic ear check-up with your audiologist
- Removing the hearing aids before sleep and keeping them tucked safely when not in use
- Replacing your hearing aid if it is an improper or loosely fit
- Discard your hearing aid only after getting it checked professionally
- Leave the hearing aids on default settings to avoid fluctuations in hearing
