Hearing loss may be caused by ageing.
Hearing loss . Hearing loss may be caused by a number of factors , including : genetics , ageing , exposure to noise , some infections , birth complications , trauma to the ear , and certain medications or toxins . Presbycusis . Hearing loss that accumulates with age but is caused by factors other than normal aging ( nosocusis and sociocusis ) is not presbycusis , although differentiating the individual effects of multiple causes of hearing loss can be difficult .
