中文摘要:
      许多城市居民喜欢在酒吧等娱乐场所享受快乐时光。但是,他们暴露在可能造成健康危害的娱乐场所环境中。这是因为人们逗留在酒吧时,会受到昏暗的灯光、二手烟和高噪声的影响。回顾了有关酒吧噪声的文献,并在香港的六家酒吧进行了噪声测量。分析结果显示,在欢乐时间即在5:00 pm和9:00 pm之间,酒吧声音水平(Leq,10-min)介于66.5~79.9 dB (A)之间,酒吧声音水平在繁忙时间即10:00 pm至11:30 pm介于69.5~97.0 dB (A)之间。在欢乐时间,最高噪音水平(Lmax)介于78.5~96.5 dB (A)之间,在繁忙时间介于80.9~107.8 dB (A)之间。分析发现,酒吧内的声音水平可以通过Leq,10-min测量,酒吧内的背景噪音则可以通过L90测量。
英文摘要:
      Many city dwellers like to enjoy the happy moments in entertainment venues such as pubs and bars. However, they are exposed to an environment that may cause health hazards. It is because people are exposed to mood lighting, second-hand smoke, and high noise levels when they stay in pubs and bars. This paper reviews the extant literature on noise in pubs and bars. Noise measurements were performed in six pubs and bars in Hong Kong SAR, China. The analyzed results show that Leq,10-min noise levels ranged from 66.5 to 79.9 dB(A) during happy hours, i.e., between 17:00 and 21:00 and Leq,10-min noise levels changed to 69.5-97.0 dB(A) during peak hours, i.e., between 22:00 and 23:30. The maximum noise levels Leq,10-min ranged from 78.5 to 96.5 dB(A) during happy hours and they changed to 80.9~107.8 dB(A) during peak hours. It was found that loudness in a pub/bar can be characterized by Leq,10-min value while noisiness, i.e., background noise can be characterized by L10 value.
