Damage to the inner ear due to aging and extensive exposure to loud noises are common causes of hearing loss, as stated by Mayo Clinic. Other causes of hearing loss include ear infections, buildup of earwax in the ear canal, tumors in the ear, and a ruptured eardrum.
Heredity plays a significant role in hearing loss, explains Mayo Clinic. Some people are more genetically susceptible to damage to the ear related to sounds and aging. People who work in noisy environments, such as farmers, construction workers and factory workers, suffer an increased risk of hearing loss. Recreational activities, such as listening to very loud music, motorcycling and snowmobiling, expose people to dangerously high noise levels that can cause hearing loss.
