HEARING AIDS AND OTHER TYPES OF AMPLIFICATION.
With the introduction of digital hearing aids the choice of models is steadily increasing. Hearing aids come in all sorts of styles, colours and strengths; however, they have some basic components:
A microphone to pick up the sound
- An amplifier to make the sound louder
- A receiver to send the sound into the ear to be heard
- A battery or some other power source
Some hearing aids can also come with additional accessories such as remote controls for easy of operation; Bluetooth devices that connect wirelessly to the TV or phone (and other phone); or chargers that work with rechargeable batteries.
