How Hearing Aids Work...
DeafHear’s Hearing Aid Service

Hearing aids are designed to amplify sound. They receive sounds, process and amplify them, and deliver them right into your ear. Here is a basic explanation of how they work.

How Hearing Aids Work

  1. Someone says ‘Hello’.
    The microphone in the hearing aid picks up the sound and converts it into an electrical signal.

  2. An amplifier then increases the strength of the signal.

  3. A receiver/speaker converts it back into sound and sends it into your inner ear.

  4. The brain “hears” and understands the sound as speech.

With all the advances in technology, computers, mobile phones and other electronic devices are now smaller and more powerful than ever before, and of course hearing aids are no exception.

The wonders of modern Hearing Aid technology

Hearing aid technology has changed dramatically with the miniaturisation of computer processors. Tiny digital processors are now used as the brains of digital hearing aids - responsible for sorting, processing and even prioritising sounds from the environment to your ear. Microtechnology has given manufacturers the ability to make hearing aids smaller, more powerful, and more effective than ever.
Digital hearing technology has made analogue technology more or less obsolete, and most manufacturers are phasing out analogue technology.

Specialized Features of Digital Hearing Aids

Modern digital hearing aids are sophisticated, state-of-the-art instruments with many different benefits and features. Processors used in digital hearing technology use complex mathematical equations to recognize types of sound inputs, process sounds (by increasing or decreasing the volume), and deliver modified sounds adjusted to match the hearing loss of the wearer. This is called digital signal processing. Digital hearing aids are so precise, they can be individually programmed to amplify certain pitch ranges according to your audiogram - or to recognise differences in consonants in speech, such as “sh” in “rash” instead of “t” as in “sat.”

Digital hearing aids have the ability to automatically detect and adjust according to the environment you are in, such as a library or a noisy restaurant, and automatically adjust to the appropriate setting for that environment. Overall, digital hearing aids deliver higher performance than ever before.

Remember, evidence shows that early intervention is more effective both in terms of rehabilitation and in how effective the hearing aids are in everyday situations. So if you or a close friend is concerned about hearing loss, the best time to act is now!
