 Modern hearing aids are like scaled-down computers that rest in your ears. There is so much technology condensed into a tiny device. Here are the elements that make up a behind-the-ear (BTE) hearing aids.
Amplifier and Microphone Each hearing aid device features a microphone which collects sound and transmits it to the amplifier. In a BTE hearing aid, both of these features are found in the sleek housing case that rests behind your ears. It is crucial that you keep this part of your hearing aid dry and clean. The majority of manufacturers advise users to wipe off your hearing aids with a soft, dry cloth when you remove them and store them away overnight. This helps to keep the microphone screen clean, and functioning properly. The Ear Hook Similar to the frames on a pair of eyeglasses, BTE hearing aids hook over the outer part of your ears. This hook, sometimes referred to as an Elbow, also attaches the microphone and amplifier case to the tubing and ear mold that rests inside your ear canal. The ear hook normally wears out and gets replaced when body sweat and oil erodes the plastic. To extend its life, it is best to use a soft cloth or tissue to thoroughly wipe the ear hook. It is essential that the hook fits comfortably on your ear, and securely attaches to the casing and tubing. Your hearing instrument specialist will be able to determine the best fit for you. Connective Tubing The plastic tubing located on the end of the ear hook transfers the sound from the microphone to the ear mold. The length of this tubing depends on what make and model your hearing aid is, and it can be customized for the best fit. Just like the ear hook, the tubing is made from plastic and will need to be replaced. You should check these tubes each day to be sure that they are securely attached to the ear hook and ear mold, and to look out for any possible damage. Earmold Earmolds rest comfortably inside your ear canal and concha bowl (the outer ear located closest to your ear canal). It gives the hearing aid an acoustic seal for the electronic sounds that the microphone is funneling inside. The fit and shape of the earmold depends on your hearing aid model and the severity of your hearing loss. Here are four of the most common types of ear molds that are available:
Hearing aid wearers frequently believe that their hearing devices are not working properly due to this switch. For BTE models, this switch is located in the casing that rests behind the ear. If you notice that your hearing aids are not working, make sure that it is switched on. It’s a good idea to switch off your hearing aids when you are not wearing them so as not to drain the batteries. Battery Compartment The majority of BTE models have a battery compartment that is found near the on/off switch. It is generally recommended that you take the batteries out and keep the compartment open overnight. This will allow the hearing aid to dry out. Hearing aid batteries last for 3 to 22 days. If your hearing aid is not functioning properly, make sure that your battery is correctly inserted in the device. If it does not work, even after you have switched it on, replace it with a new battery.
