Hearing aids are devices that amplify sound. They make soft sounds audible, normal sounds clear and loud sounds comfortable. They DO NOT, however, make your hearing normal – but attempt to give you the best possible hearing in a variety of environments. There may still be times where hearing is still difficult, such as very noisy situations. (e.g. large gathering)
HOW DO HEARING AIDS WORK?
All hearing aids have 3 basic parts: a microphone, amplifier and receiver. The microphone picks up sound from the environment. The amplifier makes it louder and the receiver directs the amplified sound back into the ear.Digital hearing aids have a microchip similar to a mini computer. It analyses the incoming sound in terms of pitch and loudness and controls the extent to how the hearing aid manipulates the sound. This is all based on the user’s hearing loss and listening preferences.
WHAT ARE THE FACTORS TO CONSIDER?
Different levels of technology are available and are chosen by the client guided by the Audiologist to match the hearing loss, lifestyle and budget of the wearer.
The cost of hearing aids is determined by the technology driving it. The more sophisticated the hearing aid, the more accurately your Audiologist can fit and adjust the hearing aid, especially with more complex hearing losses.
Hearing instruments are manufactured in various styles and are chosen using the following factors:
- Severity of hearing loss
- Size and shape of ear and ear canal
Both you and your Audiologist will choose the style that is best suited for you and your hearing loss.
