The Occupational Safety and Health Administration (OSHA) requires all employees who are exposed to noise levels with a time-weighted average of 85-decibels or more to be included in a hearing conservation program. These employees must receive audiograms on an annual basis to determine if they experience a certain level of hearing loss known as a “Standard Threshold Shift”. In addition, the facility must also evaluate feasible administrative or engineering controls to reduce employee noise exposure for all employees who are exposed to noise levels at or above OSHA’s permissible exposure limit (PEL) of 90-decibels. If no additional controls are employed, then those employees exposed to noise levels above the OSHA PEL must wear hearing protectors. It is important to remember that, according to OSHA’s Hierarchy of Controls, the use of PPE is the last step to reducing an employee’s exposure to high levels of noise, after engineering and administrative controls.
