First of all, hearing AIDS are medical devices, and they are relatively sophisticated internal medical devices, so the price of hearing AIDS is inconvenient. Cheap digital hearing AIDS are generally about 2000 yuan, which is equivalent to the price of a mid-range mobile phone. Some high-end hearing AIDS cost about 10 thousand yuan, or even 10 thousand yuan. Regarding the grade of hearing AIDS, you can read the article "Is there a second grade for hearing AIDS?" . Therefore, after choosing a hearing aid, you should take good care of it, all of which are bought with real money. We should extend the service life of hearing AIDS as much as possible, which means that we need to maintain hearing AIDS regularly.
Regular maintenance of hearing AIDS can not only prolong the service life, but also keep the sound quality of hearing AIDS at a good level, so that users can listen comfortably and clearly. Because the hearing aid is in contact with our ear canal for a long time, the ear canal usually produces earwax, which is what we often call earwax. Earwax can cause the sound hole of hearing aid to be blocked, which will affect the sound quality of hearing aid, so it should be cleaned and maintained frequently. In addition to the problem of earwax, we should also be clear that hearing AIDS are electronic devices, which are generally afraid of humidity, and then hearing AIDS often come into contact with water vapor, such as our sweat and rain outside. So always do some drying and maintenance.
Here are a few things that everyone should pay attention to at all times:
1. When the hearing aid is not in use, we should open the battery door to prevent the battery from leaking for a long time and damaging the internal parts of the hearing aid.
2. Before going to bed at night, remove the hearing aid, gently wipe it with a dry soft cloth, especially the position of earplugs and sound holes, check whether there is earwax in the sound holes, and clean it up in time. Then put the hearing aid in a special drying box.
If you sweat a lot in summer, be sure to put the hearing aid in a special drying box. If you accidentally enter the water, you should go to the fitting center for inspection in time.
4. Go to the fitting center for professional maintenance regularly.
