Noise, or unwanted sound, is one of the most common occupational hazards in American workplaces. The National Institute for Occupational Safety and Health (NIOSH) estimates that 30 million workers in the United States are exposed to hazardous noise. Exposure to high levels of noise may cause hearing loss, create physical and psychological stress, reduce productivity, interfere with communication, and contribute to accidents and injuries by making it difficult to hear warning signals.
Over 23,000 cases of occupational hearing loss that was great enough to cause hearing impairment are reported every year. Reported cases of hearing loss accounted for 14% of occupational illness and 82% of the cases involving occupational hearing loss in the manufacturing sector. Noise-related hearing loss has been listed as one of the most prevalent occupational health concerns in the United States for more than 25 years. Thousands of workers every year suffer from preventable hearing loss due to high workplace noise levels.
OSHA Stadnard, 1910.95, Occupational Noise Exposure, sets legal limits, in decibels, on noise exposure in the workplace. A decibel is the unit used to measure the intensity of a sound and we'll talk more about this later in the course. These limits are based on the average amount of time a workers is exposed to noise over an 8 hour day (called a time-weighted average). It’s important that you're familiar with two important noise level limits in the workplace:
