Which analysis focuses on noise and vibration impacts?

• A. Acoustic Analysis
• B. Visual Impact Analysis
• C. Physico-Chemical Analysis
• D. Economic Impact Analysis

Answer: (C)

Noise and vibration impacts are assessed through acoustic analysis. This approach focuses on how sound behaves in the environment—measuring sound levels, examining frequency content, and predicting how noise will propagate to nearby receptors. It compares predicted or measured levels to regulatory limits and helps design mitigations like barriers, quieter equipment, or vibration isolation. The other analyses address separate concerns: visual impact looks at how the project appears in sight, physico-chemical analysis deals with physical and chemical emissions and reactions, and economic impact analyzes costs and financial effects. So, acoustic analysis is the one that specifically concentrates on noise and vibration.
