CROS solution
A CROS or BiCROS solution consists of a transmitter and a hearing aid.
The transmitter is placed on the poorer ear. It wirelessly sends sound
from the poorer ear’s surroundings to the hearing aid placed on the
better ear.
CROS (Contralateral Routing of Signals) is a solution for people with
limited or no hearing in one ear combined with normal hearing in the
opposite ear.
BiCROS (Bilateral Contralateral Routing of Signals) is a solution for
people with limited or no hearing in one ear and hearing loss in the
opposite ear.
