The primax wireless CROS solution is designed for people who have normal hearing in one ear and un-aidable hearing loss in the other. Sounds from the un-aidable side are received by the microphones of a CROS Pure transmitter device, processed, and wirelessly transmitted to the side with normal hearing.
The primax wireless BiCROS solution is designed for people with un-aidable hearing loss in one ear and aidable hearing loss in the other. Sound from the un-aidable side is received by the CROS Pure, processed and transmitted to the primax hearing aid on the other side. The primax hearing aid delivers the combined and amplified sound from both devices into the better ear.
How it works
The primax CROS/BiCROS solution is made possible by the cosmetically attractive CROS Pure transmitter, which can be paired with virtually any other primax instrument on the contralateral ear. Like other primax hearing aids, the CROS/BiCROS solution features natural sound quality with a low noise floor which is conducive to listening comfort, and in a BiCROS set-up, to understanding of soft speech. For wearers with normal hearing in the better ear (CROS), the importance of a low noise floor should not be overlooked. In fact, it is oftentimes a crucial factor in terms of spontaneous acceptance. The low noise floor is also a key differentiator between the primax CROS solution and similar existing products on the market.
The primax CROS/BiCROS solution features automatic, adaptive directionality for noisy situations, making speech understanding easier, and reducing listening effort. The CROS Pure directional microphones feature an innovative polar pattern focused to the front and skewed towards the side. This directional signal is then transmitted to the other side before the signal is either delivered to the ear alone in the CROS solution, or combined with the ipsilateral signal in the BiCROS solution. In other words, even in noisy situations, the CROS benefit is maintained, and does not significantly compromise battery life.
