What are hearing aids?

Hearing aids are classified as medical apparatuses with the appearance of a small electronic device that is made with the specific purpose of improving an individual’s hearing by amplifying and processing certain sounds. In doing so, hearing aids help improve the quality of life of its users by assisting them in listening, communicating and participating more effectively in normal daily activities. These devices also aid in making sounds more comfortable and more intelligible, benefiting the user in both noisy and quiet situations.


A hearing aid should always be specifically configured to suit its user by matching their type of hearing loss, lifestyle and physical features. This is supported by verification of the hearing aids, using equipment specifically for this purpose. This process is called “fitting” and can only be performed by a trained audiologist such as Dr Tanja Beeton.


The sound processing ability of these devices is impressive; they can highlight sound regions, highlight voices, eliminate noise or wind and shift frequencies. This makes hearing aids an indispensable medical device for any person that is hearing impaired.

How does hearing aid work?

In order to understand exactly how a hearing aid works, it is essential that one understands what a hearing aid consists of. A hearing aid is essentially comprised of the following parts:


  • Microphone: The microphone picks up sounds from the surrounding environment and changes it from an acoustical signal to an electronic one.


  • Processor: The processor applies changes to the electrical signal received from the microphone by determining which sounds to amplify and to what extent it should be amplified, all according to a patient’s hearing test results.


  • Digital hearing aids process sound into numerical codes, such as the binary codes in computers. The hearing aids themselves have powerful chipsets and are computers in their own right. When the digital circuitry has converted the acoustic energy into code, the sound can be specifically adjusted the individual hearing aid user’s needs, and to specific listening environments.


  • Amplifier/speaker: An amplifier or speaker changes the electrical signal back to a louder acoustic one.


In essence, a hearing aid works by having the microphone pick up sounds that are then sent via the processor to the amplifier which then makes the sound louder. Depending on the shape of a patient’s hearing loss, a hearing aid is able to make some pitches louder than others. An audiologist will adjust a hearing aid to suit a patient’s specific needs by using a computer program and verification system.


A verification system is an independent measuring tool that measures the sound at the eardrum. This is a system that can help the audiologist determine objectively how much amplification is needed. This is to ensure that the hearing aid gives as much amplification as needed with soft, medium and loud sounds, and to ensure that the loud sounds are not overly loud.
