Maintenance and care of hearing aids   A hearing aid is a high-tech device that deserves a lot of care, should be kept clean and free of earwax, should not be exposed to excessive heat or moisture, also when you are not using the hearing aid should be stored in a case as they are easy to lose. These measures will help to prolong the functionality of the hearing aids and avoid great discomfort. The following are recommendations for the care of hearing aids: Dehumidifier for hearing aids Investing in a hearing aid dehumidifier is a good decision; they have the ability to dry the digital circuits that are inside your hearing aids. As the day progresses, the humidity, the sweat of the ear, the earwax, can dampen the hearing aids. For this reason, a hearing aid dehumidifier is very useful and will allow you to enjoy your day normally, without worrying about the humidity that accumulates inside the hearing aids. You must bear in mind that these devices can add years of useful life to your hearing aids. The accumulation of moisture is one of the most common causes of hearing aid repairs. If you buy a dehumidifier, these repairs will be avoided. If you do not have a hearing aid dehumidifier, be sure to air your hearing aid before going to sleep. This outdoor drying keeps the circuits running smoothly and provides the opportunity for the hearing aids to dry out at night. It also saves battery life. Cleans the earwax in hearing aids The earwax can get into the hearing aids and damage them, clog the hearing aid speaker or microphone, causing the hearing aid not to perform optimally. Earwax, along with moisture, is one of the most common reasons why hearing aids are sent to manufacturers for repairs. With proper care and cleaning, you can reduce the negative effects that earwax causes on your hearing aids. The first step you should take when removing your hearing aids is to clean the outer casings with a soft cloth to remove any remaining earwax, residue or oils. Often the earwax is simply found in the outer shell and can be easily cleaned. The second step is the cleaning of the atrial opening and/or the auricular tube, which is the end that enters the ear canal. If it is covered with earwax, you will have significant performance problems, experiencing a sensation of reduced sound volume.   Clean the microphone screen of the hearing aid If the hearing aid's microphones are clogged with debris, they will not be able to transmit the sounds around you clearly. The ideal is to obtain a clear signal to be processed and amplified in order to cover your hearing needs. Although earwax is not as likely to plug the microphones, it can be a crucial factor for users who use CIC-type hearing aids, because they are completely inserted into the ear canal. CICs, when introduced deeper into the ear canal, are more susceptible to the side effects of earwax. The problems that a dirty microphone screen can cause consist of a decrease in the overall volume and the effectiveness of the directional microphone in the background noise. Change the slim tube in BTE hearing aids BTE hearing aids must be connected to the mold through a slim thin plastic tube. Over time, this flexible and soft tube can harden and crack, which affects the acoustic efficiency of the tube. The sound may sound muffled and you may hear a kind of permanent whistle. How often should I change hearing aid’s slim tube? The response varies from person to person; there are several factors that influence this decision, for example, fats on the skin of the user. On average, most people require a tube change once a year; however, some may require changes more often. Avoid extreme heat and cold In order to prevent any failure in the operation of the hearing aids, it is advisable to keep them at a temperature of 15 Cº to 40 Cº.
