CROS for Blind Persons With Unilateral Hearing Loss

William Rintelmann, PhD; Earl Harford, PhD; Samuel Burchfield, MA

Arch Otolaryngol. 1970;91(3):284-288.

Abstract
This preliminary report based on two clinical cases suggests that the contralateral routing of signals (CROS) by a hearing aid has potential value in the habilitation of blind persons with a profound unilateral hearing loss. The CROS hearing aid can be substantially beneficial in mobility training by providing clues for locating the source of sounds, even though environmental sounds are being received by just one ear. A rationale is presented concerning this special method of auditory localization.
