Dr. John Howard, director of the U.S. National Institute for Occupational Safety and Health (NIOSH) conducted a research on the effect of loud noise on health. Loud noise is one of the most common workplace hazards, regular exposure to loud noise increases high blood pressure and cholesterol levels. High blood pressure and high cholesterol levels cause heart disease.
Scientists analyzed data from National Health Interview Survey and discovered that many workers had a history of noise exposure at work, some of them had temporary and permanent hearing loss, lost of coordination and concentration, fatigue, high blood pressure and high cholesterol.
Work-related noise exposure could be linked to 58 percent of hearing problems, 14 percent of high blood pressure and 9 percent of high cholesterol cases. Industries with the highest rates of worker noise exposure are mining, welding, construction and manufacturing.
