What is a Hearing Aid?

hearing aids

A hearing aid is a complex and intelligent communication device, which is designed to help you to distinguish sounds across every frequency and to participate fully in the world around you.

There are many different types of hearing aids, as there are many different types of hearing loss,   but all work to amplify sounds within a particular hearing range, making sounds louder and clearer. No hearing aid can restore perfect hearing, but the way in which they work can help you to hear many different sounds more clearly and even to detect sounds you may not have heard for many years.

At Hidden Hearing we have a wide range of excellent digital hearing aids. Our national network includes over eight branches and clinics, so we’re sure to have a location near you.

How Hearing Aids Work?

how hearing aids work

A hearing aid has three basic parts: a microphone, an amplifier and a speaker.

1. Sound enters the hearing aid through a microphone.
A microphone, set within the small hearing aid that you wear in your ear, picks up sounds around you.

2. Sound is processed and amplified.
Sounds are then analysed via the processing chip in the hearing aid, and processed sounds are sent to the amplifier.

3. Sound is delivered to a receiver.
Amplified sounds are sent to the loudspeaker inside the hearing aid device, which then transmits sounds into the inner ear where they are transformed into electrical impulses.

The brain receives these electrical impulses and processes them to create audible sounds.

Hearing aids are designed to work with the specific hearing loss problems you are suffering, so they will vary in design and you will work with a hearing loss professional to find the best hearing aid for you.

Hearing Aid Technology

Oticon hearing instruments with BrainHearing™ technology are designed for your brain, supporting the hard work it does. BrainHearing™ helps you hear better, with less effort so you can participate more actively in life.


There are two types of sound processing technology that may be used in hearing aids: analogue and digital technology. In all hearing aids, sounds are detected by a microphone, processed and amplified, and delivered to a loudspeaker or receiver.

Amplified sound output is sent directly to your ear canal, either through tubing to an ear mould and then into the ear canal, or through a thin wire to a receiver, which is worn inside the ear.

Types of Hearing Aids

Conventionally, hearing instruments sit behind the ear. However, there are now small hearing aids and even invisible hearing aids that sit so well concealed in the ear canal that no one can see them.

Behind the Ear Hearing Aids

Behind-the-Ear (BTE) hearing aids are the most common on the market today. They hide behind the Auricle (the visible part of your ear) and have a thin clear tube that runs into the ear canal. BTEs are designed so people do not notice them but remain extremely effective at treating hearing loss.

It transmits sound through a thin tube that runs from the top-front of the ear and into your ear canal. Behind-the-ear hearing aids are suitable for most types of hearing loss.

In the Ear Hearing Aids

Hidden Inside Your Ear
In The Ear (ITE) models are a good choice if discretion is a high priority for you. They help to give first-time users an easy introduction to hearing aids because they sit safely out of the way of sunglasses and goggles – and won’t fly off when you remove your sweater.

Analogue Hearing Aids

Sounds are processed as electrical signals by a microphone within an analogue hearing aid device. The sound is registered and you receive an impression, or picture of it. The original sound is copied by the processor, which means that the sound can deteriorate as it is processed and it is only possible to improve sounds to a certain extent.

Digital Hearing Aids

Digital hearing aids convert the acoustic signal into digits and process these, before converting them back into analogue acoustic signals for the listener. A digital signal does not deteriorate or wear out, so can be duplicated endlessly without any negative effect on the quality of the sound.

The newest technology uses wireless communication to process sounds and produce clearer speech and sound quality, while also allowing you to listen more easily and to connect to mobile phones and MP3 players.

First of all, what is Bluetooth? Bluetooth is a wireless communication platform that allows for the transfer of data between two or more electronic devices. Bluetooth technology transmits data through high frequency radio waves, allowing you to listen to music, watch movies, and talk on the phone “hands-free” – or without needing a cord running from your device to your headphones. Since Bluetooth’s invention in the 1990’s, a large variety of products have incorporated the technology, including computers, tablets, televisions, mobile phones, music players – and, as we’ll discuss in depth in this article, hearing aids .
