How Does A Hearing Aid Work | The Science Behind Better Hearing

Understanding primary functions helps a lot

If you are enduring diminished hearing capabilities, or you know that you have existing ear problems, obtaining a hearing aid might be the answer. However, it might be beneficial to know how they work, without delving into the technicalities of audiological science.

Put simply, a hearing aid is a small electronic device that works by amplifying sounds so that the wearer can discern specific noises, hear more succinctly and gain from greater volume. There are two main fitments, behind-the-ear, or within-the-ear, and they consist of the following components:

  • A microphone
  • An amplifier
  • A speaker
  • A battery

Sounds are picked-up by the microphone (of which there might be more than one), which are converted into electrical waves that are passed through the amplifier, which boosts their potency. They are released into the ear via the speaker.

While a lot of people will, through pride, obstinacy, or a relative lack of immediate concern, recognise that their hearing needs some help but put-off any necessary auditory test, perhaps they ought to regard hearing reduction with the same seriousness as a change in sight. The ear test is as free of charge as an eye test. If you are in any doubt at all, do not delay and make an auditory test request as soon as you can

Once hearing quality starts to diminish, it can be a slow but sure procedure that it can worsen. To maintain a higher quality of life, both sight and sound senses are more important than either smell, or taste, not least because to lose either of them will impact heavily on both lifestyle and life expectancy.
