The signs and symptoms of hearing loss may be evident when an affected child speaks in an inappropriately loud voice or frequently asks for repeating statements. Hearing loss can either be unilateral or bilateral. Hearing loss can be ‘conductive’ or ‘sensori-neural’. Conductive hearing loss results in disruption in the conduction of sound between the external and the middle ear. This usually affects one ear and is reversible in most of the conditions. Sensori-neural hearing loss results from damage to the inner ear or auditory nerve. Auditory nerve is responsible for transmitting nerve impulses between the brain and the inner ear. The hearing loss may be accompanied by other symptoms like ear pain and ringing in the ears, depending upon the underlying ear ailment.
