Users are very concerned about how long the service life of hearing aids is when choosing hearing aids. The product packaging says 5 years, some people say that it has not been broken for 10 years, and some people say that it has been broken for two or three years. Which is more accurate? Next, we will look at what causes the damage of hearing aids from the perspective of maintenance engineers, and whether we can get some ways to “extend” the life of hearing aids.

Point 1

As told by the maintenance engineers,It is very common that the protective layer, the support, the solder joints and the movement are seriously corroded, which is mixed with salt and metal oxides.The reason for this is the prolonged “soaking” of sweat. Some people may ask,isn’t the hearing aid waterproof? The answer is yes. Many of today’s hearing aids have reached IP68 in terms of dust and water resistance. However, sweat is not the same as water, and there are salts and other substances in it, which are corrosive. Long-term sweat “soaking” will destroy the protective layer of the hearing aid, and eventually damage the electronic circuit inside, causing damage to the hearing aid. Therefore, in daily use, it is very important to prevent and wipe sweat and remove moisture.

In addition, moisture is also important. Long-term exposure to a humid environment will not only affect the performance of hearing aids, but may also cause failure. It is recommended that when the hearing aid is not used for a long time (such as sleeping), it should be put into the matching drying box, and tighten the lid. Users living in humid areas and climates should pay particular attention.

Point 2

Some corrosion is caused by electrical leakage.The hearing aid battery contains electrolyte, which is highly corrosive. In the case of moisture, sweat erosion or improper storage, the quality of the battery is unstable and there may be leakage. Therefore, the battery should be removed when the hearing aid is not in use, and do not simply turn off the hearing aid. When wiping the hearing aid, the battery should also be wiped. Batteries should be stored in a cool, dry place at room temperature, away from direct sunlight; Don’t put it in the car.

Point 3

Wearing hearing aids incorrectly. Long-term use of incorrect wearing methods can also damage hearing aids. This is a process from quantity to quality. Such as the ear hook tube appears to be broken. The correct wearing method can not only protect the hearing aid, but also protect our ears and improve the comfort of wearing.

These are some of the common causes of hearing aid damage seen from the maintenance perspective. Hearing aids are electronic devices that are used close to the skin. In order to ensure that it has a good performance, avoid or reduce the occurrence of failures, should master the correct use of methods, pay attention to cleaning and maintenance, develop good use habits, both to avoid or reduce the occurrence of damage, but also conducive to the extension of service life.
