This type of hearing loss relates to when the outer and middle ear are working effectively, so the cause of the hearing loss is somewhere in the inner ear. Sensorineural deafness usually means the cochlear is not working effectively. The cochlear is part of the auditory system that creates electrical signals and sends them along the auditory nerve to the brain. In most cases it is a permanent hearing loss. A hearing loss can be mild, moderate , severe or profound. Harry has a profound bi- lateral ( both sides) hearing loss.
