Analysis of the causes of hearing aid damage

The hearing aids we often say mainly refer to the hearing aids of international big brands. These hearing aid manufacturers have a reputation. After years of development, the robust conditions of the equipment have made the hearing aids not so easy to damage, but we still encounter equipment in actual use. The problem of failure, in addition to the factors of the device itself, the three reasons that cause the most damage are the human factors we often ignore.
The use of hearing aids in different regions is different. This is a problem that we often overlook. For example, we found the dry maintenance method of hearing aids on the Internet. It helps the hearing device dry for 6 hours every day and dry all night because of different life in different regions. The environment is different, so the personalized maintenance method is the king of extending the life of the equipment. In addition to the failure of the hearing aid itself, earwax damage, equipment moisture, and drop shock are the three main causes of hearing aid damage.
Many people have not noticed that their earwax is also the main cause of hearing aid damage. Most people think that their earwax will only block the receiver. In fact, there are more deep damages.

Asian earwax is mostly dry. Most of the earwax in daily life will fall out of the ear canal, but some of it remains in the ear canal, especially those who wear hearing aids. After the ear canal is blocked, the earwax cannot be properly removed. Come out, so some earwax will block the hole of the receiver. Under normal circumstances, it will only make the sound lighter, but the long-term blockage will cause the receiver to be damaged.

For ear canal or deep ear canal hearing aids, the main parts of the hearing aid are close to the receiver, and the acid and alkali components of the earwax can easily damage the main parts of the hearing aid. In the routine maintenance of hearing aids, it is necessary to clean the earwax remaining in the receiver or the sound tube.

Earwax is the most easily overlooked cause of hearing aid damage. Although it will not cause large losses in most cases, it will often bring a lot of inconvenience to the use of hearing aids. Therefore, the receiver is often cleaned to keep the sound transmission. Good condition.


2, the device is damp

1, ear wax damage
It is necessary to specify that the dampness here is not caused by natural wear and tear, but by damp caused by human inattention.

Most parts of southern China have humid weather, and some parts of the north also have water mist weather in winter, which is the fuse for hearing aids. If the surface of the hearing aid is dried with water droplets or water vapor, it must be wiped off with a non-woven fabric. Many people just pick up the hearing aid after washing their hands, causing the hearing aid to be covered with water drops. If they feel dry anyway, they should be placed directly into the dry. Box, this is very wrong. When the water vapor enters the hearing aid from the battery compartment door or the knob gap, it will not act immediately, but will accumulate, slowly eroding the internal wiring of the hearing aid, causing the volume of the inner cavity of the casing to store water vapor, corrode the movement and internal wiring.

Most hearing aids are now waterproof, so being slightly wetted by rain does not directly cause damage to the hearing aid, but if it is not wiped clean, putting it directly into the drying box may cause corrosion or damage to the equipment. As for how long it takes to dry, it is determined by the local climate. Usually, 6-8 hours is enough, that is, a whole night.
3. Drop impact
If we dissect the hearing aid device, we will find that the components of the hearing aid are actually connected by very small boards or wires. These devices may be damaged after being subjected to severe shocks, especially the receiver is very structural due to its structure. It is easy to shift and deform after impact, causing distortion or silence.

In addition to the behind-the-ear hearing aids, custom hearing aids are very easy to fall. We often think that custom hearing aids are more solid, actually the same fear of falling, and the impact will cause different degrees of damage.
