Hearing aids are considered as mini-computers because each part must work together for a successful operation. While you may not grasp its entire process, it’s essential to learn how each component works for easier troubleshooting. Keep on reading to find out more.
The body of the hearing aid is the largest and most visible part. This hard plastic shell protects the battery and other essential components. One of those vital parts is the microphone, which catches the sound before sending it to the amplifier. Microphones of modern hearing aids are so sensitive that they can filter speech amidst background noise to make it easier for a person to understand conversations.
Meanwhile, the amplifier transforms the sound waves into an electrical signal and sends it to the speaker. Amplification adjustments depend on the level of hearing loss which only a qualified hearing healthcare professional can diagnose. Some hearing aids also have a telecoil, which makes hearing during public occasions easier.
Finally, the battery powers the device, and it can either be disposable or rechargeable. Hearing aids often use replaceable batteries like those in wristwatches. Manufacturers highly recommend wiping the hearing aid with a soft, dry cloth before storing it away to maintain the microphone’s smooth operation. Keeping it in a dehumidifier extends its life due to the removal of excess moisture.
Several RITE hearing aids have a button or switch that can be programmed to perform a variety of functions. The hearing care specialist can add settings to increase or decrease the volume, depending on the hearing environment. Make an appointment with your hearing aid specialist if you’re not sure on how to operate the button. Once you switch on the hearing aid, the speaker receives power and signals through a plastic-coated wire.
The receiver delivers the sound to your ear after the microphone’s processing and the amplifier’s conversion of audio to electric impulses. Domes or earmolds enclose this hearing aid element depending on the severity of hearing loss and the patient’s preference. Hearing aids for those with mild to moderate hearing loss often come with domes that become invisible when worn correctly.
This small silicone part goes deep into the ear canal while keeping its connection to the hearing aid’s tube. While domes often take the form of a bell or a mushroom, hearing care professionals can alter its shape and size to fit the patient’s ear canal. Ill-fitting domes will not capture the sound well while only registering annoying feedback.
You can prolong the dome’s efficiency by wiping it with a soft cloth every evening and by regularly changing its complimentary earwax guards. Regular inspection of hearing aid domes, especially its attachment with the tubing, will help determine if it’s time to replace it as well. Swapping domes won’t be a concern because they’re inexpensive and easy to install.
