What are the types of hearing aids?
There’s a hearing aid for nearly any type of hearing difficulty - and you can choose one based on your personal needs and preferences. Most hearing aids have one or two microphones, an amplifier and a speaker (also called the “receiver”). Sounds are absorbed by the microphones, processed into electrical signals and then delivered amplified to your ear. The good news is that hearing aids are much smaller and more discreet than in the past.
Three hearing aid categories
Behind-the-ear (BTE) hearing aids
BTE hearing aids work for all degrees of hearing loss. They fit comfortably, and their small size makes them hardly visible behind the ear. Amplified sounds are led directly into your ear canal via a thin, almost invisible tube. A custom-made earpiece (earmold) maximizes your comfort and fit. BTE devices have more space for electronics compared to other designs. This allows for a wide range of technical options including high amplification and wireless connectivity.
Receiver-in-canal (RIC)/external receiver aids
Smaller than standard BTE models, RIC hearing aids are available for mild to severe hearing impairments. These devices are worn comfortably and almost invisibly behind the ear. Unlike BTE devices, RIC models have a loudspeaker or “receiver” located outside of the housing at the end of a thin cable. This delivers sound into the ear canal near the eardrum. RIC devices require less distance to transmit sound which means lower energy use and longer battery life.
In-the-ear (ITE) hearing aids
ITE hearing aids, also called in-ear (IE) hearing aids, are worn entirely in the auricle or ear canal. The ITE hearing aid electronics are packaged into a custom-made hollow shell. This way ITE devices can make use of the anatomical advantages of the external ear. An ITE device works well for people with mild to severe hearing loss.
In-ear hearing aids come in three types: in the auricle, partly in the ear canal or completely in the ear canal (this makes them 100% invisible). Models worn in the ear canal may not be suitable for everyone as your ear anatomy must be able to fit the device. Modern behind-the-ear devices are also very discreet and attractive. Even if you can’t wear an in-ear device, people still will hardly notice you wear a hearing aid.
"Contact lens" for the ear
The Lyric from Phonak is the first completely invisible, in ear hearing aid. Launched a few years ago, the Lyric fits deep inside the ear canal - just 4 mm in front of the ear drum. This device remains in place for several months. However, not all types of hearing loss or ear anatomies are suitable. Call 1300 353 186 and find out if the Lyric might work for you.
