| 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。无论来自街道外部、设备内部还是其他建筑使用者的背景噪音，都可能造成干扰并妨碍清晰的交流。另一方面，完全的安静在大多数空间里既不切实际也不合适。在某些空间（如学校教室）中，声学的作用更大。 |

| 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: | 绿色建筑提供具有良好声学效果的室内环境。空间的具体声学需求在同一栋建筑内也会有所不同。为正确设计建筑内每个空间的声学环境，项目团队需要考虑： |
| • Acoustic expectations based on the space's use and occupant needs (e.g., a classroom needs to be quieter than a hallway) | • 基于空间用途和使用者需求的声学期望（例如，教室需要比走廊更安静） |
| • Noise exposure based on proximity to sources of potential background noises (e.g., spaces near a conference room in an office may be noisy) | • 基于与潜在背景噪声源距离的噪声暴露（例如，办公室中靠近会议室的空间可能比较嘈杂） |
| • Acoustic comfort requirements (e.g., a restaurant can be louder than a residential unit) | • 声学舒适度要求（例如，餐厅可以比住宅单元更嘈杂） |
| • Acoustic privacy requirements (e.g., people in the waiting room of a medical office should not be able to hear conversations in patient rooms) | • 声学隐私要求（例如，医务室候诊区的人不应能听到诊室内的对话） |
| • Communication requirements (e.g., people need to hear a whisper in an auditorium) | • 交流要求（例如，在礼堂中人们需要能听到耳语） |
| 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. | 一旦确定了每个空间的声学需求，项目团队就可以为每个空间确定解决方案。解决方案包括选择能够减少声音传播（如隔离噪声）和吸收混响的材料（如墙壁、天花板、地板）；安装声音掩蔽系统；改变房间形状；以及提供一致性的背景声。机械系统（如暖通空调）的布置也需要考虑，因为可能需要采取噪声隔离措施，以防止其产生的噪声传播到建筑使用者。 |
