There are often children’s parents asking: children wear hearing aids are always loud, and parents can hear a lot of squeaks, isn’t it loud noise? Or: every time children wear hearing aids, there are squeaks, they don’t wear them, but children can hear when they sleep under the pressure of hearing aids or wearing hats, what’s the reason?

In fact, these problems are what we often call “scream”, also known as “acoustic feedback”, which is a normal situation in the work of hearing aids, indicating that the hearing aids are in a normal working state. As long as you wear it correctly, the “scream” can be eliminated

The common causes of children’s hearing aids are as follows:

1. Incorrect wearing method of ear mold

For the children who wear hearing aids for the first time, because the parents are not familiar with the wearing method of the ear mold, they do not wear the ear mold in place when they wear it at the initial stage, resulting in a gap between the ear mold and the ear canal, thus generating acoustic feedback. Parents should learn the right way to wear earmuffs as soon as possible to avoid screaming.

2. Changes of ear canal

Children are in the stage of growth and development, and their auditory canal is also changing. The ear mold is made according to the child’s ear canal. Due to the development of the ear canal, a pair of ear molds can’t fully fit the ear canal after being used for a period of time, so there will be a scream. At this time, children should regularly replace the ear mold, according to different development speed, generally 6-12 months to replace.

3. Cerumen blockage in ear canal

After the hearing aid is worn, the cerumen in the ear canal is not easy to be discharged in time, which is easy to cause cerumen accumulation. The sound of the hearing aid enters the ear canal and is blocked by cerumen, and then it is reflected, resulting in howling. It is suggested that the wearer of hearing aid should go to the hearing center regularly to check the ear canal, and clean up in time in case of cerumen blockage.

4. Improper production of ear mold

At present, most of the ear molds are made after the ear molds are taken manually. Due to the poor cooperation between children and adults, if there is any disorder or scratching in the process of taking the ear molds, the quality of the ear molds may be poor, the ear canal depth of the ear molds made is not enough or the seal is not tight, so after wearing, it may also produce a howl. At this time, it is necessary to take the ear impression again and make the ear impression again.

5. The ear mold is damaged or the ear hook is damaged

In the process of using ear mold and hearing aid, due to the corrosion of sweat and grease behind the ear, the material of ear mold sound tube and ear mold will be aged and hard, and the interface of ear hook is also easy to loosen and age. Once there is a gap, the sound will leak out from the gap and produce a harsh scream. It is recommended to carefully observe the hearing aid and ear mold after screaming, find cracks or hardening of the acoustic tube, and timely replace the ear mold or ear hook at the sound hearing center of Haizhi.

6. Hearing aid internal component failure

It is inevitable for children to bump or wrestle when wearing hearing aids. Hearing aids are electronic products. Although they have passed strict factory inspection, if they often bump or wrestle in the wearing process, it is easy to cause looseness or failure of internal components of hearing aids, resulting in screaming. This kind of situation is called internal squeal of hearing aids. Once it is judged that it is internal squeal, the hearing aids need to be returned to the factory for maintenance. There is a very small chance of squealing inside the hearing aid. Try to avoid bumping during normal use. Put the special protection box for hearing aid when you go out.

All of the above are the common causes and solutions of squealing of hearing aids. Most of the squealing can be solved by wearing hearing aids again or making ear molds again.
