What is the difference between Analog and Digital Hearing Aids?
Thanks Ashleigh for sharing such information.
Good afternoon MainakSantra1
Digital aids are the latest, most advanced kind and are fitted routinely and as standard on the NHS. In fact, analogue technology has largely been phased out. However, body-worn aids and some bone-conduction types are analogue and will continue to be available for use in exceptional circumstances where they are required.
Analogue and digital hearing aids both have similar components. Both types pick up sound using a microphone and use circuitry to amplify sound. They both run on batteries and use a receiver to deliver sound into the ear. The difference between analogue and digital hearing aids is the type of technology that is used to amplify sounds.
Analogue hearing aids work by making continuous sound waves louder, amplify all sounds (speech and noise). Some analog hearing aids are programmable, containing a microchip which stores multiple program settings for various listening environments.
Digital aids take the signal from their microphone and convert it into ‘bits’ of data – numbers that can be manipulated by a tiny computer in each hearing aid. This means that the person fitting your hearing aids can tailor the sound precisely to suit your hearing loss. You may also be able to switch between different settings suitable for different listening conditions. Many digital aids adjust themselves automatically to suit different sound environments.
I hope this helps.
