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.
Continue reading to learn more about directional hearing and to find out how CROS and BiCROS hearing aids can help with unilateral hearing loss.
The importance of directional hearing
When listening with two healthy ears (binaural hearing), sound reaches both of them at different volumes and frequencies. This allows the brain to localize the direction of the sounds for orientation purposes. Therefore, an individual with binaural hearing will be able to easily locate the source of any given noise. This is called directional hearing.
In contrast, those with unilateral hearing loss will only hear on the side of their healthy ear. Because of this, they lose the ability to orientate the location of sounds. Unfortunately, turning one’s head does not help in these types of situations. Additionally, those with unilateral hearing loss also find it difficult to concentrate on a specific sound – like speech – when in noisy environments, making it a challenge to carry conversations in public places.
In conventional hearing aids, the microphone and receiver are close together, amplifying the signal at the respective ear. However, to help those with single-sided deafness, engineers have developed the CROS hearing aid, where the receiver and microphone are decoupled and attached at different locations.
With CROS hearing aids, a microphone records sound from the individual’s deaf side and transfers it directly into a receiver in the healthy ear. This does not influence the healthy ear’s normal capacity. Rather, it permits sounds arriving at the impaired ear to be recorded, processed by the brain, and ultimately heard. In short, a variation of directional hearing is made possible once again.
CROS hearing aids: wireless and discreet
Hearing aid manufacturers, 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.
