How Do Hearing Aids Work

A hearing aid is a discrete electronic device worn behind or in the ear. It amplifies some sounds to help to listen, communicate and carry out daily tasks simpler for someone with hearing loss. People with Hearing Aids Adelaide can hear more clearly in calm and noisy environments. Check out our website to have complete insight. However, only around one in five individuals who would benefit from a hearing aid actually wears one. 

However, only around one in five people who may benefit from a hearing aid really do. A hearing aid comprises a speaker, an amplifier, and a microphone. The hearing aid’s microphone captures sound, converts it into electrical impulses, and sends those signals to an amplifier. A speaker amplifies the impulses before being sent to the ear.

Different styles of hearing aids

Behind-the-ear (BTE)- A hard plastic case worn behind the ear and a hard plastic earmold that fits within the outer ear make up a hearing aid. The case behind the ear is where the electronic components are kept. The earmold serves as a conduit for a sound that enters the ear from the hearing aid. People of all ages use BTE devices for mild to severe hearing loss. An open-fit hearing aid is a new type of BTE device. 

In-the-ear (ITE)- Adelaide hearing aids are used for mild to severe hearing loss and entirely fit inside the outer ear. The hard plastic shell that houses the electronic components is created. A telecoil is one of the extra characteristics that some ITE aids may have. A telecoil is a tiny magnetic coil that enables users to receive sound via the hearing aid’s electronics instead of its microphone. This makes telephone talks easier to hear.

Canal- Aids come in two designs and fit into the ear canal. The in-the-canal (ITC) hearing aid is designed to fit the ear canal’s dimensions and form. A completely-in-canal (CIC) hearing aid is practically buried in the ear canal. For mild to moderately severe hearing loss, both types are employed. Canal aids may be challenging for a person to adjust and remove due to their small size. 

Analog and digital electronics are the two primary categories.

Analog- Analog devices turn sound waves into amplified electrical signals. Hearing aids that are analog and customizable are explicitly made for each user. The manufacturer programs the device in accordance with the recommendations made by your audiologist. Hearing aids that are analog or programmable have multiple settings or programs. The aid can be computer-programmed by an audiologist. You can alter the program for various hearing conditions, including small, quiet rooms, crowded restaurants, and vast, open spaces like theaters or stadiums. 

Digital- Before being amplified, digital aids convert sound waves into numerical codes resembling a computer’s binary code. The aid can be specifically customized to enhance some frequencies more than others because the code also contains information about a sound’s pitch or volume. These tools can also be programmed to pay attention to sounds coming from a particular angle. All varieties of hearing aids can employ digital circuitry.


When you think of how common hearing loss is, it can be hard to believe that so few people wear hearing aids. Regardless of the reason behind your decision not to use one or the hearing aid options available and their varying price tags, we hope that you’ll consider giving Adelaide Hearing a chance. You may very well be pleasantly surprised by how much they change your life for the better.
