In BERDE, indoor acoustical quality is addressed through which measures?

• A. Only occupant comfort surveys.
• B. Through sound-attenuation strategies, acoustic zoning, and low-noise equipment.
• C. Through landscaping and water features.
• D. Energy performance targets only.

Answer: (B)

Indoor acoustical quality is addressed by actively shaping the sound environment through design and equipment choices. Sound-attenuation strategies involve selecting materials and assemblies that absorb or block noise, such as acoustical ceilings, wall absorbers, and well-sealed partitions, which cut down on noise transmission and reverberation. Acoustic zoning means organizing spaces so that noisier areas are separated from quiet zones, reducing how much noise travels between rooms and ensuring appropriate acoustical conditions for different uses. Low-noise equipment focuses on choosing and installing HVAC, motors, and other machinery that run quietly and with minimal vibration, further lowering ambient sound levels. Together, these measures directly improve occupant comfort, speech intelligibility, and overall indoor environment. In contrast, relying only on occupant comfort surveys doesn’t create the physical sound environment, landscaping or water features mainly affect exterior or outdoor acoustics, and energy performance targets center on energy use rather than indoor sound quality.
