Urban Acoustic Ecology: Measuring Soundscapes to Inform Residential Ventilation System Design
城市声学生态学：测量声景以指导住宅通风系统设计
-
Residential ventilation units must balance fresh-air intake with exterior noise intrusion—especially near transit corridors where broadband L<sub>Aeq</sub> exceeds 65 dB.住宅通风设备须在引入新风与隔绝外部噪声之间取得平衡——尤其在交通干道附近，宽带等效声压级（L<sub>Aeq</sub>）超过65分贝时。
