Hearing aids – the latest, digital, discreet or invisible
Hearing aids are actually fairly simple devices, which consist of four main parts – a microphone, to pick up the sound; an amplifier, to increase volume and send it to the receiver; a receiver which changes an electrical signal into sound and sends it into the ear; and a battery to provide power.
Unfortunately, not all hearing aids are suitable for hearing loss. You need to have some inner ear hair cells to pick up vibrations from the hearing aid and convert those vibrations into nerve signals. And, in a lot of cases, even if you do have some hair cells, a hearing aid won’t completely restore normal hearing – but it will help. How much, depends on each individual and their particular hearing loss.
That’s why you need experienced, impartial and professional advice.
