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.
