Hearing Aids Explained
Hearing aids are small, battery-powered electronic devices that enhance sounds to make them louder and clearer, helping someone with hearing loss to hear better and feel less isolated in everyday situations.
There are many different shapes and styles of hearing aids, they can be worn on the ear or in the ear. However, they all work in a similar way using the same five elements:
- Microphone – picks up sound and converts it into digital signals
- Amplifier – modulates the digital signals, makes sounds louder or quieter
- Receiver - converts the amplified signal into sounds and feeds them into the ear
- Microchip – enables the tuning and personalisation of your hearing aid to your individual needs
- Battery – the hearing aid gets power from tiny batteries
Today’s digital hearing aids are small and discreet, they come with advanced technological features to help them adapt to different hearing environments. Modern digital hearing aids are designed to identify and amplify speech rather than background noise. Despite being extremely complicated on the inside, digital hearing aids remain very user friendly and a reliable way to improve your hearing.
Everyone’s hearing requirements are different, so the digital hearing aid you choose will be programmed to your individual needs. A prescription is created from the hearing test completed in the hearing aid assessment, allowing the audiologist to program your hearing aid/s accordingly.
