Many traffic safety jobs involve exposure to significant noise. OSHA requires employers to implement a hearing conservation program when noise exposure is at or above 85 decibels averaged over eight working hours, or an eight-hour, time-weighted average. Hearing conservation programs strive to prevent initial occupational hearing loss, preserve and protect remaining hearing, and equip workers with the knowledge and hearing protection devices necessary to safeguard themselves. Explore the fundamentals of noise exposure, discuss potential hearing protections and leave with examples of how hearing protection can improve communication and productivity.
