All hearing instruments are powered by battery. They consist of a microphone which picks up the sounds, an amplifier which processes and amplifies the sounds, and a receiver or loudspeaker which sends the sounds into the ear canal.
Finding the perfect fit
Hearing instruments can be customised to your ear shape, hearing loss level, lifestyle, preference for style/colour and different listening environments. Your clinician can help choose the right instrument for you.
Types of hearing instruments:
Completely-in-the-canal hearing instrument (CIC). This is the smallest instrument and fits entirely within the ear canal. Can be used with hearing protection headphones.
In-the-canal hearing instrument (ITC). This sits inside the ear and can be fitted with manual controls. Suits mild to moderate hearing losses.
In-the-ear hearing instrument (ITE). This sits in the ear and may be visible (depending on size). Can be prescribed with a directional microphone.
Behind-the-ear (BTE). This sits behind the ear. Can be fitted to all degrees of hearing loss. Available in various colours and sizes.
Open fit micro BTE. A small, cosmetically-appealing instrument that sits behind the ear usually fitted with a slim tube. Designed for high-frequency hearing losses.
Invisible Open Technology (IOT)
One of the world's smallest hearing device, the microphone and tubing follow the individual's ear contours, which make them virtually invisible. IOT allows air to travel in and out of the ear canal providing a natural listening experience.
