Why Do Hearing Aids Whistle? Causes & Solutions
By Team Hearzap | Sept. 26, 2024
Hearing aids help people hear better and enjoy life. However, many users have complained about a whistling sound called feedback. You can improve your hearing experience by understanding what causes this feedback and taking steps to fix it.
Common Causes of Hearing Aids Feedback
Feedback in hearing aids occurs when sound from the hearing aid's speaker escapes back into the microphone, creating a loop that amplifies the sound until it results in a high-pitched whistle. This can be frustrating for users, but it’s important to note that feedback is not indicative of a malfunction. Instead, it is often a sign that the device needs adjustment or that it is not fitting properly.
Several factors can contribute to feedback in hearing aids:
- The fit of a hearing aid is very important. If the hearing aid doesn’t sit properly in your ear, sound can escape easily. This can cause a problem known as feedback. To prevent this, it’s a good idea to check how the hearing aid fits in your ear regularly. Many hearing aids can be customized to fit your ear shape, and proper fitting can help improve sound quality and reduce feedback.
- Earwax is a natural substance that protects your ears, but sometimes too much of it can build up. When there is excess earwax, it can block the pathway for sound, making it harder for you to hear. This blockage can also lead to feedback in your hearing aid, creating an annoying sound.
- The volume setting on your hearing aid is crucial for good sound quality. If the volume is turned up too high, it can cause distortion and feedback. Hearing aids should be set to a level that is comfortable for you, where you can hear clearly without straining.
- Devices like microwaves, Wi-Fi routers, and computers emit electromagnetic fields (EMFs) that can interfere with hearing aids. This interference may cause feedback, which sounds like a high-pitched squeal, and can distort the sound quality, making it difficult for users to hear clearly.
- Hearing aids are sensitive devices that can break easily. If the hearing aid has been dropped or hit, it might be damaged inside, which could cause problems like feedback.
Steps to Reduce Feedback
If you experience feedback with your hearing aids, here are some steps to take:
- The position of your hearing aid can affect its performance leading to feedback. To resolve this issue, gently remove the hearing aid and then reinsert it, making sure it fits snugly in your ear. You should feel a comfortable fit without any gaps.
- Keeping your hearing aids clean is essential for their performance. Make it a habit to clean your hearing aids regularly using a soft, dry cloth. You can also use a small brush or specialized cleaning tools designed for hearing aids to gently remove any buildup.
- If the volume is set too high, it can lead to feedback. To find a solution, try lowering the volume to see if that helps reduce or eliminate the feedback. It’s important to find a comfortable volume level that allows you to hear conversations and sounds clearly without straining. Remember, louder isn’t always better; setting the volume too high can create more problems, including increased feedback.
- To minimize electromagnetic fields, users can maintain a safe distance from these devices while they are in use, avoid using them simultaneously with their hearing aids, and adjust their surroundings to reduce exposure to electromagnetic fields.
- If you suspect your hearing aid is damaged or notice any problems like weird sounds, low volume, or feedback, you should take it to a hearing care professional.
Professional Audiologist Check
It’s important to have your hearing aids regularly checked by a qualified audiologist to ensure they are working properly. An audiologist can evaluate the fit, function, and settings of your hearing aids, making any necessary adjustments to optimize their performance. Over time, factors like changes in your ear shape, wax buildup, or evolving hearing needs can affect how well your hearing aids function.
If you notice persistent feedback or other issues, an appointment with your audiologist can help identify the cause and provide personalized solutions. Regular check-ups ensure your hearing aids continue to meet your needs effectively.
