Which of the following elements should be considered to facilitate communication in school classrooms?(Choose 3)
A: Air filters with high MERV ratings
B: Building geometry
C: Increased ventilation
D: Soft surfaces
E: Duct insulation

参考答案: BDE

本题解释:
正确答案：BDE
系统解析: B:The geometry of the space is critical to good acoustics. Consider a concert hall - are the acoustics good or bad? Probably good because of the effort put into the geometry of the space. There are designs that improve acoustics (like a concert hall) and designs that make for poor acoustics (such as high ceilings in a classroom).

D:Architectural finishes that include soft surfaces improve acoustics. Fabric-covered walls or acoustic tiles are some examples.

E:Air flowing through the HVAC system can make loud whistling and whooshing noises. Duct insulation reduces the noise of the air flow.

A:Air filters with higher MERV ratings do a better job filtering out air contaminants. They do not impact noise in the HVAC system.

C:Increasing the ventilation will improve indoor air quality.

Notes:

This question is asking about good acoustic design.
