CROS and BiCROS hearing aids
Cutting-edge technology for your ears
With all of today’s advancements in technology, it’s easy to find a hearing solution tailored to your individual needs. For example, if you have a form of unilateral hearing loss (single-sided deafness), new CROS (“Contralateral Routing of Signal”) or BiCROS hearing aids will not only improve your ability to hear, but they can help with directional hearing, allowing you to localize sounds and pinpoint exactly where they’re coming from.

CROS hearing aids: wireless and discreet
Hearing aid manufacturers, such as Widex and Phonak, have developed cutting-edge technology that transmits sound wirelessly from one hearing aid to the other via radio signals.
To allow sound to reach the unimpaired ear accurately and quickly, an audiologist will need to make a cast of your ear. This ensures that the fitted audio piece (the otoplasty) is able to fit comfortably into your ear canal and have the best precision possible. Depending on the manufacturer of your CROS hearing aid, the technical accessories for the devices may vary slightly. CROS hearing aids are available in behind-the-ear (BTE) and in-the-ear (ITE) versions, which are connected to the otoplasty. In the BTE version, the microphone is located behind the impaired ear, while the receiver is located behind the healthy ear. All of these components are discreet, comfortable, and improve hearing tremendously.
The magic of BiCROS hearing aids
BiCROS hearing aids are worn by individuals who have severe hearing loss in one ear, and minor hearing loss in the other. Like with CROS hearing aids, the microphone records the signal at the impaired ear and transmits it wirelessly to the other. However, since the other ear also has an impairment, this side has an additional microphone, which can also receive signals. Both signals are then amplified to enable the best possible hearing.
