Acoustics 声环境
Sound impacts people's comfort in a space. Background noise, whether from the street outside, equipment inside, or other building occupants, can be a distraction and hinder clear communication. On the other hand, total silence is not practical or appropriate in most spaces. Acoustics play an even bigger role in certain spaces, such as classrooms in schools.
声音会影响人们在空间中的舒适度。背景噪音（来自室外街道、室内设备或其他使用者）会分散注意力，干扰清晰沟通。另一方面，完全静音在大多数空间中既不现实也不合适。在教室等特定场所，声学设计尤为重要。
Green Building Strategies 绿色建筑策略
Green buildings provide indoor environments with good acoustics. The specific acoustic needs of a space vary even within a building. To properly design the acoustic environment for each space within a building, project teams need to consider the:
- Acoustic expectations based on the space's use and occupant needs (e.g., a classroom needs to be quieter than a hallway)
- Noise exposure based on proximity to sources of potential background noises (e.g., spaces near a conference room in an office may be noisy)
- Acoustic comfort requirements (e.g., a restaurant can be louder than a residential unit)
- Acoustic privacy requirements (e.g., people in the waiting room of a medical office should not be able to hear conversations in patient rooms)
- Communication requirements (e.g., people need to hear a whisper in an auditorium)
绿色建筑致力于打造声学环境良好的室内空间。即使在同一栋建筑中，不同空间的声学需求也存在差异。为合理设计每个空间的声环境，项目团队需考虑：
- 基于空间用途与使用者需求的声学预期（例如，教室需要比走廊更安静）
- 因靠近潜在背景噪音源而产生的噪音暴露风险（例如，办公室会议室附近的空间可能较嘈杂）
- 声学舒适度要求（例如，餐厅可接受的噪音水平高于住宅）
- 声学隐私需求（例如，医院候诊区人员不应听到诊室对话）
- 沟通需求（例如，礼堂内需要听清低声对话）
Once the acoustic needs for each space have been determined, project teams can identify solutions for each space. Solutions include selecting materials (e.g., walls, ceilings, flooring) that reduce sound transmissions (e.g., isolate the noise) and absorb reverberation; installing sound masking systems; altering the shape of the room; and providing consistent background sound. Placement of mechanical systems (e.g., HVAC) also needs to be considered, since noise isolation may be needed to prevent the noise they generate from reaching building occupants.
确定每个空间的声学需求后，项目团队可针对性制定解决方案，包括：选用可降低声音传播（隔音）并吸收混响的材料（如墙面、天花板、地板）；安装声掩蔽系统；优化房间形状；提供稳定的背景音。此外，还需考虑机电系统（如暖通空调）的布置，通过隔音措施避免其产生的噪音影响使用者。
