CROS hearing aid

CROS hearing aid

A contralateral routing of signals (CROS) [Harford, E., Barry, J. (1965). A rehabilitative approach to the problem of unilateral hearing impairment: Contralateral routing of signals (CROS). J Speech Hear Dis, 30, 121-138.] hearing aid is a type of hearing aid that is used to treat unilateral hearing loss. It takes sound from the ear with poorer hearing and transmits to the ear with better hearing.

Systems can involve two behind-the-ear units connected either by wire or by wireless transmission. There are also systems incorporated into eyeglasses. BAHA CROS systems use the conductivity of the skull to transmit sound.
