How Does a Hearing Aid Work?

A hearing aid is a hearing device that is designed to receive, amplify, and clarify sounds for people who struggle with hearing loss. There are many different types of hearing aids that are available today, but they all have the same basic components that make them effective:

  • Microphone to receive sounds
  • Amplifier for strengthening sounds
  • Receiver or speaker to translate sounds
  • Battery for powering the device

There are more than 35 million people in the United States that have some level of hearing loss. Fortunately, the technology of the hearing device has come very far and allows people to get more from their hearing aids than ever before.

Different Aids for Different Issues

All hearing aids are a little different, even though they have similar components and construction. The areas where you will find variances in your hearing aid selection include:

  • Designs and styles
  • Technology used and sound style (digital vs. analog)
  • Special features


Some hearing aids are designed to fit behind the ear, and are most commonly used for children because of their durability and ease of growing with the child over time. Other models are more discreet and offer complete invisibility in some cases, allowing everyone to get the hearing support that they need regardless of the hearing device that they choose.

Technology Counts

When it comes to how hearing aids work, technology plays a vital role in today’s models. With tiny microchips and circuitry, modern hearing aids are much different than those of years past. Digital technology is always better than analog sound. Thanks to technology, some people who couldn’t benefit from hearing aids in the past can now use them regularly to enjoy the sounds of the world around them.
