Which statement about noise-reduction on construction sites is supported by the material?

• A. Relocating noisy equipment
• B. Erecting sound barriers
• C. Both relocating equipment and barriers
• D. Neither

Answer: (C)

Reducing noise exposure on construction sites comes from addressing noise at multiple points: the source and the path to workers. Moving loud equipment away from workers lowers the sound level at their location simply by increasing distance and using the surrounding space to shield them. Erecting sound barriers provides a physical obstacle that blocks or dampens the noise traveling toward workers and sensitive areas. When you use both approaches, you get the combined benefit of reducing the noise at the source and cutting the noise that reaches people, leading to greater overall exposure reduction. The material supports that both relocating equipment and installing barriers contribute to noise reduction, so choosing both methods aligns with effective practice.
