Which term refers to sources of noise that may affect on and off-base communities?

• A. Noise Surveys
• B. Community Noise
• C. Criterion Level
• D. Exchange Rate

Answer: (B)

Community noise refers to noise sources that may affect people living or working near a base, both on the installation and in surrounding areas. This term covers the kinds of sounds from operations like aircraft, ground vehicles, and construction that can be heard by the general public, not just within the base boundaries. It’s about the impact on the community, which is why it’s the best answer for sources that may affect on- and off-base areas.

Noise surveys are methods for measuring noise levels, not the sources themselves. Criterion level is the allowable noise limit used to judge compliance, not a source. Exchange rate is a factor used in calculating how noise propagates and is perceived, not a source category.
