Which factor includes the distance to noise sources and whether the worker is stationary or moves?

• A. Hearing conservation
• B. Worker position
• C. Environmental quality
• D. Inventory

Answer: (B)

The key idea is how exposure to noise changes with where the worker is relative to the noise sources and whether they are moving. Sound intensity drops with distance, so the farther you are from a noise source, the lower the exposure at your ears. If you stay in one spot, your exposure tends to be steady, but if you move around, you encounter different sound levels over time, and the total daily dose becomes a matter of how long you spend in each position. In practice, this is handled by measuring or estimating exposure with dosimeters or time-weighted averages to account for movement and varying distances to sources. That’s why the factor described is the worker’s position. Hearing conservation and environmental quality relate to protection strategies and overall conditions, but they don’t specifically capture how distance and movement affect noise exposure. Inventory isn’t related to noise exposure.
