Single-Sided Hearing Loss
Solutions for people with hearing loss in mainly one ear
We typically recommend either a CROS or a BiCROS system. A CROS system consists of a single
microphone and single receiver contained in two individual devices (one for each ear). The
ear with little-to-no functional hearing is fit with the microphone-equipped device, and the
ear with normal hearing is fit with the receiver-equipped device. Sound arriving at the ear
with hearing loss will then transmit through a wireless connection to the receiver-equipped
device on the normal-hearing ear — to help you hear sounds regardless of which side they’re
coming from.
A BiCROS system consists of a microphone-equipped device that is fit to the poorer-hearing
ear and a conventional hearing aid fit to the better-hearing ear that has some hearing loss.
