Which pair correctly describes the residential limit and regulatory goal for Community Noise?

• A. Residential limit 65 dBA; regulatory goal 55 dBA
• B. Residential limit 55 dBA; regulatory goal 65 dBA
• C. Residential limit 50 dBA; regulatory goal 60 dBA
• D. Residential limit 70 dBA; regulatory goal 75 dBA

Answer: (B)

Understanding how community noise is managed, we separate a fixed residential noise limit from a regulatory goal. The limit is the maximum exterior noise level that must not be exceeded in residential areas to protect inhabitants. The regulatory goal is the target level the regulation aims to reach through planning, zoning, and abatement strategies. In this question, the residential limit is 55 dBA, a protective threshold, while the regulatory goal is 65 dBA, providing a stated objective for improvement that the regulatory program pursues over time. The gap between the limit and the goal creates a realistic path for implementation: enforce the tighter limit now and work toward achieving the broader goal through measures like soundproofing, smoother land-use transitions, and source controls. Other pairings would either propose a less protective limit or invert the relationship, which doesn’t align with how these two concepts interact in regulatory practice.
