CROS Hearing Aids
CROS hearing aids: double-sided sound
On top of the six main types of hearing aids, there is one other type that has a different functionality. They are called CROS hearing aids, which stands for “Contralateral Routing of Signal”. They are meant for people who have severe hearing loss, including deafness, in only one ear, but whose other ear does not have hearing loss.
BiCROS Hearing Aids
People who have severe hearing loss, or deafness, in one ear and minor hearing loss in the other can use BiCROS hearing aids.
- Sound sychronisationAs with CROS hearing aids, the microphone in your ear with profound hearing loss picks up sound and sends it to the hearing aid in the other ear
- Amplifies sound separatelySince your other ear also has hearing loss, it has its own microphone and sound processor in order to amplify sound from the side of your other ear.
- Natural soundBoth hearing aids are received, processed and amplified separately so you hear them together in a more natural manner.
Advantages
- Smaller and more discreet main unit than BTE hearing aid models
- Has a more open fit, which provides a more natural sound quality of the wearer's own voice
- Still a bigger size for larger batteries, longer battery life, and rechargeable hearing aids
- The most common hearing aid type that has rechargeable battery models
- Typically more powerful sound amplification and advanced technology and features
- The receiver can be replaced separately from the main unit
Disadvantages
More visible and less discreet than other, smaller hearing aid types- May pick up more wind noise than other styles
- May not be suitable for people who wear eyeglasses
- Blocks up more of your ear, which can make wearers feel plugged up
- The receiver in the ear is more prone to damage from moisture and blockage from earwax
