What You Need to Know About Hearing Aids


Considering hearing aids? Find out how hearing aids are made and how well they work. Hearing loss can impact a person’s life in both notable and unseen ways, from decreased quality of life to struggling to make sense of others’ speech, especially in a noisy or busy environment.

According to a 2017 report by Today Online, an estimated 422,000 older adults in Singapore suffer from hearing loss and over 100,000 may have a disabling hearing impairment – and it doesn’t stop there. These numbers are expected to double by 2030.

For Singaporeans and people all around the world who are struggling with hearing loss or hearing difficulties, the invention of the hearing aid has proven to be one of the most useful medical and technological advancements of the modern world.

What is a hearing aid and how does it work?

Hearing aids can either be worn behind or inside the ear and are usually made up of five parts.

  • A small microphone to pick up sound
  • A microchip that will cater the received sound for the best experience to the specific user
  • An amplifier to increase the source sound
  • A loudspeaker to output the sound for the user
  • A battery to power the whole process

While hearing aids may be getting smaller and more discreet in size, modern options are getting smarter and more powerful. The current models are fully digital devices, designed to provide crisp and clear sound quality while incorporating some of the latest surround sound technology.

With today’s advancements, digital hearing aids can also be personalised to meet the needs of each individual. The user can control the direction sounds are coming from, eliminate excess noise, and choose to connect to a variety of electronic devices.

Hearing aids work through a step-by-step process

Initially, the microphone will pick up the sound as your ear normally would, the chip analyses the sounds, processes them and sends them to the amplifier.

The actual sounds are then transmitted via the loudspeaker into the appropriate destination within the ear.

In the inner ear, these sounds are modified into electrical impulses where the brain then processes them.

But it is actually the brain, and not the ear, that processes the sounds we hear—the ear is simply the funnel.

The job of hearing aids is to improve the effectiveness of a damaged ear at getting those sounds to the brain where they can then be understood by an individual.
