What is a Hearing Instrument?
A hearing instrument is basically a miniature amplification system.
Each hearing instrument is individually designed and fitted for one person’s particular
hearing situation. This is because each person is an individual with different acoustic needs.

Every hearing instrument has the following components:
- A microphone
- An amplifier (Most have digital signal processing)
- A miniature loudspeaker called a receiver
- Either an ear mould (a piece of acrylic or silicon material individually formed that fits in the ear.)
or individual shell for custom instruments.
- A battery
