In the summer, people sweat more, sometimes affecting the use of hearing aids, in the winter does not sweat, whether hearing aids do not need to maintain it, the answer is obviously no, why?
Although there is no sweat in winter, there is another problem: condensation.
Condensation is the liquefaction of water vapor in the cold, there is water vapor in the air, when we go from indoors to outdoors, there is a temperature difference, the water vapor inside the sound tube of the hearing aid will be liquefied in the cold, the formation of condensate clogging the sound tube, resulting in hearing aids, no sound.
Note: How to maintain the hearing aid behind the ear machine in winter first of all to check the acoustic tube: before use, check the hearing aid acoustic tube (that is, connecting the hearing aid and the ear mold between the plastic short tube) whether there is a water droplet block, if there is a droplet of water should be shaken off or wiped clean in a timely manner. Otherwise, it will affect the sound conduction and cause the user to feel that the sound becomes smaller or even no sound.
Now that the weather is getting cooler, condensation, the mortal enemy of customizers, has begun to act again.
It is well known that the return rate of behind-the-ear (BTE) hearing aids is more than double in summer due to the effects of sweat and water. However, customized machines (especially those of the auricular cavity type) have a winter repair rate that is three times that of other seasons. This seemingly unbelievable phenomenon is actually a result of condensation generated inside the hearing aid causing the malfunction.
In winter, due to the high temperature and humidity inside the ear canal, but the temperature outside the hearing aid in contact with the air part of the temperature may be around 5-10 degrees, then the moisture inside the ear canal will enter the receiver and condense in the internal, which will block the sound hole, resulting in the sound of the hearing aid is sporadic, or to the afternoon of every day began to be silent, and placed a night on the good. Go to a service center for maintenance or use an electronic dryer to dry your hearing aids.
Secondly, remove the plastic film from the battery: when replacing the battery with a new one for your hearing aid, remove the plastic film from the battery and rub the positive terminal of the battery with your hand before placing it in the hearing aid, as this will help the battery to work better.
