Hearing aid technology


There are two main types of technology used in today’s hearing aids:


Analogue hearing aids are designed with a particular frequency based on your audiogram (a measurement graph used by the hearing specialist to determine your level of hearing loss). The hearing specialist then tells the hearing aid manufacturer what settings to install. This technology can be suitable for many different types of hearing loss.


Digital hearing aids use digitised sound processing (DSP) via a computer chip to convert sound waves into digital signals and determine whether the sound is noise or speech. The hearing aid then makes modifications to provide a clear, amplified, distortion-free signal.

Hearing aids that use this type of technology generally has a longer life span and may provide better hearing for you in different listening situations.
