What does a noise source survey do?

• A. It measures ambient noise in the entire workspace
• B. It evaluates PPE fit
• C. It defines PPE color
• D. It classifies whether a noise source output exceeds the criterion level of 85 dBA and could present a potential exposure hazard to workers

Answer: (D)

A noise source survey focuses on identifying and quantifying the noise emitted by individual sources to see if any single source could push worker exposure above a defined criterion, such as 85 dBA. By measuring the sound level emitted by specific equipment or processes, you classify which sources are potential hazards and warrant controls. This helps prioritize actions like engineering changes to reduce noise at the source, or applying hearing protection or administrative controls, rather than just measuring overall ambient noise. It’s about pinpointing the loud sources and deciding if they meet or exceed the threshold that signals a potential hazard.
