The ability to predict road noise in urban area is important. The community noise equivalent level (L(den)) varies from day to day (weekdays, weekends, holidays, etc.). There is a need to compromise between the accuracy in the determination of L(den) and limited resources of input data, the measuring equipment, and time. The problem can be managed using the method proposed in this study. It requires only one short-term measurement of the time-average sound level, L(Aeq,T).
预测城市地区道路噪声的能力很重要。社区噪声等效声级（L(den)）每天（工作日、周末、节假日等）都会有所不同。在确定L(den)的准确性与输入数据、测量设备和时间等有限资源之间需要进行权衡。使用本研究中提出的方法可以解决这个问题。它只需要对时间平均声级L(Aeq,T)进行一次短期测量。
