Elevated workplace or environmental noise can cause hearing impairment, tinnitus, hypertension, ischemic heart disease, annoyance, and sleep disturbance. [3][4] Changes in the immune system and birth defects have been also attributed to noise exposure. [5] Although age-related health effects (presbycusis) occur naturally with age, [6] in many ...
