The sound is received by the microphone of the hearing aid, which is then converted into a digital sign
The strength of this digital sign is increased by the amplifier
The speaker then passes the sound into the ear.
Behind-the-ear (BTE) hearing aids are great hearing aids for every level of hearing loss. These hearing aids are sleek devices that sit snug behind the ear. A very small, clear tube runs from the hearing aid to your ear canal so that sounds easily reach your ears. BTE hearing aids are perfect for people of all ages and they have powerful batteries that can treat severe and profound hearing loss, as well as running complex programs and features.
Receiver-in-canal (RIC) devices have a lot in common with BTE hearing aids. Most of the hearing aid components are in a sophisticated case behind the ear. However, the receiver sits in the ear canal. A very thin wire connects the two parts of the device, and overall, the RIC hearing aids are slightly smaller than BTE devices.
In-the-ear (ITE) hearing aids rest in the outer ear. There are no components behind the ear. ITE devices are small, but they still have a powerful battery. These devices are recommended for anyone with mild to severe hearing loss. Many ITE hearing aids can be controlled using an app on your phone, so you won’t have to fiddle with changing settings on the device.
In-the-canal (ITC) hearing aids are even smaller than ITE hearing aids. ITC devices are in a case so small it can sit inside the top of your ear canal. You’ll only see a portion of the hearing aid and the rest will be hidden from view. These devices are custom molded to your unique ear canal. ITC hearing aids work best for people with mild to moderate hearing loss.
Completely-in-canal (CIC) hearing devices are placed even further in the ear canal than ITC hearing aids and they’re almost impossible to see. These devices are controlled remotely and they’re a great choice for people with mild to moderate hearing loss.
Hearing aids have a microphone that is sensitive enough to pick up on all the sounds around you. These sophisticated microphones can even differentiate between sounds. For example, they can identify which sounds are speech sounds you want to hear and which sounds are distracting background sounds you don’t want to hear. The microphone will also convert the sound waves into electrical signals and send them to the processor.
The most complex part of the hearing aid is the processor or amplifier. This is a small computer chip that can manipulate and change the electrical signals. When sounds reach the processor, they are changed to match your hearing. Certain sounds will be amplified while other sounds will be reduced. Any feedback or other interference is also reduced. If you have your tinnitus therapy program turned on, the processor also adds these features.
Once the sound has been manipulated, the sound is sent to the receiver. This part of the hearing aid will convert the digital signals back into sound waves, create audible sound and direct that sound into your ears.
