Noise as an Occupational Hazard
Noise, or unwanted sound, is one of the most prevalent occupational hazards in U.S. workplaces. According to the National Institute for Occupational Safety and Health (NIOSH), approximately 30 million workers in the United States are exposed to potentially harmful noise levels. Prolonged exposure to high noise can lead to hearing loss, physical and psychological stress, reduced productivity, communication difficulties, and an increased risk of accidents due to the inability to hear warning signals.
This course provides an introduction to the fundamentals of sound, the effects of excessive workplace noise on hearing, and the strategies for protecting hearing. Topics include the Hierarchy of Controls for noise, the types of hearing protection available, and an overview of the Hearing Conservation Program and employee training requirements.
