Hearing aids are a valuable tool for individuals who experience hearing loss, allowing them to better communicate with others and enjoy a fuller life. However, hearing aids can sometimes whistle, which can be frustrating and embarrassing for the wearer. In this blog, we will explore why do hearing aids whistle and what can be done to prevent it.
The whistling sound that occurs in hearing aids is called feedback. Feedback occurs when sound from the hearing aid’s speaker is picked up by the microphone and then re-amplified, creating a loop of sound that results in a high-pitched whistle. Feedback is more likely to occur when the hearing aid is placed too close to the microphone or when the hearing aid’s settings are not properly calibrated.
Why do Hearing Aids Whistle?
There are several reasons why hearing aids may whistle:
- Poor fit: If the hearing aid does not fit properly in the ear canal or sits too far out, it can cause feedback.
- Earwax buildup: Earwax can accumulate in the ear canal, blocking sound from the hearing aid and causing feedback.
- Volume setting: If the volume of the hearing aid is set too high, it can cause feedback.
- Loose parts: Loose or damaged parts in the hearing aid can cause feedback.
- Interference: Electronic devices, such as cell phones, can interfere with the hearing aid’s microphone, causing feedback.
So, What can be done to prevent hearing aids from whistling?
- Proper fit: Ensuring that the hearing aid is properly fit in the ear canal can help prevent feedback.
- Regular cleaning: Regularly cleaning the hearing aid and the ear canal can prevent earwax buildup.
- Volume adjustment: Adjusting the volume of the hearing aid to an appropriate level can help prevent feedback.
- Maintenance: Regular maintenance of the hearing aid can help prevent loose or damaged parts.
- Avoiding interference: Keeping electronic devices away from the hearing aid can help prevent interference.
In conclusion, hearing aids whistle due to feedback, which can be caused by a poor fit, earwax buildup, improper volume settings, loose parts, and interference from electronic devices. By following the tips above, you can help prevent hearing aids from whistling and enjoy clearer, more comfortable hearing.
It’s always important to consult with a hearing healthcare professional if you are experiencing problems with your hearing aids or if you have any concerns.
