What should I do if my hearing aid is malfunctioning? At this time, in addition to returning to the factory for repair, there are some situations that we can solve by ourselves.
Next, please learn about hearing aid failures with Hearing Sense.
Hearing aid sounds are intermittent
1. Low battery
When the battery is low, it will make the energy supply of the hearing aid unbalanced, resulting in intermittent volume output.
2. Hearing aid output limit
For some hearing aids that use "peak shaving" for output limitation, if the maximum output value is blindly reduced, it will cause the hearing aid to shave more peaks and the distortion is obvious, resulting in the user not being able to hear a larger sound or the sound is intermittent.
Precautions: Regular battery replacement, no use of waste batteries, etc. are necessary for daily maintenance of hearing aids.
Hearing aids are screaming
1. Ear mold ear sample preparation is not appropriate
Users with heavy hearing loss generally need to customize the ear mold, but if the ear sample is not appropriate and cannot be matched with the user's ear canal, the sound will leak out from the gap between the ear canal and the ear mold, resulting in a whistle.
2. The ear hook is broken
At present, most of the ear hooks used in the back of the ear machine are made of plastic material, and long-term use may cause the combination of the ear hook and the hearing aid body to crack, resulting in sound leakage and whistling.
3. The ventilation hole size is not suitable
Ventilation holes are often used to improve the wearing comfort of hearing aid users and solve the ear plugging effect. However, if the vents are not properly sized, they will produce a whistle due to excessive sound leakage.
4. Check the microphone or receiver
Block the inlet of the hearing aid with your fingers, and if the hearing aid continues to whistle, you can tell that the internal whistle is coming from the microphone.
If the hearing aid continues to whistle, it can be judged that the internal whistle is from the receiver.
In this case, it is necessary to return to the factory for repair.
Note: The whistle can be divided into two types: external whistle and internal whistle, and the user and the fitter can deal with it through the correct judgment method.
The hearing aid sound is unusually faint
1. Battery usage is too long
First of all, we have to check the battery, if the use time is too long, it will cause the output volume of the hearing aid to be weak, at this time you can consider replacing the hearing aid battery.
2. Anti-earwax mesh cover clogging
If you are a custom machine, you can check the anti-earwax mesh cover, because this anti-earwax device is susceptible to cerumen clogging. If you find that there is no abnormality in the sound after removing the anti-earwax mesh cover, it means that the mesh cover is the cause of the problem.
3. Damper clogging
For back-of-the-ear machines, it is possible to check the damper placed in the ear hook, because during use it is susceptible to crusts and oily secretions, which hinder the sound. If the ear hook is removed, the hearing aid has no abnormality in the sound, and it can be used normally after replacing the ear hook.
Precautions: Regular care and maintenance is very important for the moisture and scale of hearing aids, and cerumen blockage is an important reason for hearing aids to be repaired.
If you encounter the above situation in the process of using hearing aids, you must communicate with your own fitting agent in time to solve the problem together!
