Advice for Hearing Aid Users on Hearing Aid Malfunctions
Hello.
The faults in hearing aids can arise from various reasons. Therefore, as experts in diagnosing hearing aid malfunctions, we must have a good understanding of the mechanical working principles of the devices and explain the issues that users need to pay attention to in detail. In this text, I have listed some of the major hearing aid malfunctions and my recommendations to hearing aid users based on my work experience and theoretical knowledge as well as the feedback received from my clients. I hope you find it informative.
1. No sound coming from the hearing aid:
One of the most common complaints I receive is about no sound coming from the hearing aid. This problem can usually be resolved easily. The lack of sound from the hearing aid may be due to a problem with the hearing aid battery and contacts. Therefore, the first step is to ensure that the battery is properly inserted into the device and is working. Then, the battery contacts should be gently cleaned with the help of a cotton swab. If there is no problem with the battery, it should be ensured that the tube is not blocked for behind-the-ear devices, and the filter is clean for in-the-ear devices. If necessary, the filter and tube should be replaced. These steps will help most users resolve the problem. However, if the problem persists despite these methods, the microphone part of the device should be gently brushed while holding the hearing aid downward. If this method does not work either, the device should be taken to a technical service for replacement or repair.
2. Whistling or buzzing sound from hearing aids:
Hearing aid whistling or buzzing is also a common problem. Improper application of the venting holes, excessive gain setting, incorrect fitting of the ear mold or poor ear mold fit can cause this issue. In addition, earwax, ear canal blockage, or dirt buildup in the hearing aid parts such as the hose or filter can also cause whistling. If any of these issues occur, they must be addressed directly. In the case of behind-the-ear (BTE) hearing aids, if an objective whistling sound is heard when the horn is blocked with the hand or when using a stethoscope, there may be a speaker malfunction, and the device may need to be repaired or have parts replaced. In this case, the hearing aid should be directed to a technical service.
3.Not hearing natural sound from the hearing aid:
The problem of not getting natural sound from a hearing aid usually manifests itself as sounds coming out “muffled” when low frequencies are not given the necessary amplification, or high-frequency sounds being set too sharp. When there is not enough ventilation opening, the patient will also hear their own voice as if they were in a tunnel. After acoustic modification, the correct device selection and programming, it should also be checked if there is any earwax in the user’s ears. Additionally, when the user has an illness such as a cold or flu, they will not perceive sounds as natural.
4.Intermittent Cutting of the Sound of the Hearing Aid:
There are many reasons that can affect the performance of a hearing aid, from the expiration of the battery life to the accumulation of earwax, clogged filters and hoses. If the problem is not solved after routine checks, the feedback cancellation feature found in certain hearing aids should be evaluated. When the feedback cancellation feature is set to quickly activate, there may be interruptions in the device’s sound due to differences in intensity between environments. If a solution cannot be found even after expert programming, technical support should be sought.
As it can be understood, many criteria need to be taken into consideration for proper performance from hearing aids. Above, I mentioned frequently encountered complaints and their basic solution methods. As with any digital device, users also play a significant role in the longevity of hearing aids. Regular maintenance and inspection of hearing aids can prevent simple and easily solvable malfunctions and malfunctions that require technical service.
Points to be considered by users of hearing aids:
1-Contact with water or moisture: Even if hearing aids are waterproof, the device should be removed during activities such as showering, swimming, or ablutions, and should not be worn until the ear is dry. If the device comes into contact with water, the battery should be immediately removed and the device should be left to dry for a few hours. Under no circumstances should a hot air blowing tool such as a hair dryer be used.
2-Not removing the battery during unused periods: Especially in hot environmental conditions, zinc batteries can cause leakage. In this case, mechanical parts of the hearing aid (microphone, speaker, etc.) may be damaged. Even if there is no leakage or oxidation in the hearing aid battery, leaving the battery constantly plugged in the device will shorten the battery life.
3-Neglecting the cleaning of the hearing aid: Routine cleaning of hearing aids should be done every day. The surface of the hearing aid should be cleaned with wet wipes that do not contain alcohol. This is because the device is coated with a hydrophobic coating that is sensitive to alcohol. Water should not be allowed to enter the device during the cleaning process. Regular filter changes in in-ear devices and hose changes in behind-the-ear devices are very important. These points should be paid more attention in case of conditions such as ear discharge, eczema, etc. In case of discomfort, an appointment with an ENT specialist should be made to find a solution.
4-Taking an MRI or X-ray with the hearing aid: Using a hearing aid during X-ray imaging frequently causes damage to the main board of the hearing aid and leaves permanent damage. In such cases, the hearing aid should be removed.
ADDITIONAL TIPS: Users who experience excessive sweating may use moisture-absorbing tablets, which can be obtained from hearing aid centers, especially if they are using in-ear hearing aids. For behind-the-ear hearing aid users, it is recommended to use a blower to remove dust and moisture that accumulates in the hose.
Thank you for reading, I am open to your suggestions and recommendations, and will update the text periodically based on my experiences. Have a nice day.
