Although aging is the biggest predictor of hearing loss, it is far from the only risk factor. Individuals with these characteristics also show a higher risk of hearing loss:
A family history of hearing loss, since some types of hearing loss have a genetic component
Chronic exposure to loud noises such as rock concerts, motorcycle engines, or gunshot blasts
Occupational noise exposure, particularly among those who work in construction, agriculture, or manufacturing
Taking certain medications, including Viagra and some chemotherapy drugs
A history of certain illnesses, including meningitis
Noise is measured in units called decibels, or dB. Exposure to sounds louder than 85 dB, which is about the level of traffic on a busy city street, can permanently damage hearing. Fortunately, noise-induced hearing loss is completely preventable with the use of ear protection. You should also avoid listening to loud music through headphones.
