在卡塞雷斯市（西班牙埃斯特雷马杜拉）进行了城市噪声调查。为了选择不同的测量点，街道根据它们在城市不同区域的交通中的用途进行了分类。所考虑的四类道路均为直通道路（不包括服务道路）：中心区以外的主干道、中心区的主干道、连接不同区域的其他双向道路、其他单向道路。前两个类别被发现是统计上难以区分的，并且与第三个类别一起具有最高的噪声水平-中值Leq超过70 dB（A）。单向道路的噪音较低，约为5分贝（A）。因此，卡塞雷斯这个小城市的声级相当高，在工作时间内，我们90%的测量值超过65 dB（A）的Leq。最后，建立了等效声级、交通流量和主要噪声声级之间的关系，其结果与其他作者的结果吻合较好。我们还可以得出结论，城市噪音可以有效地研究分类的街道，根据其用途。(C)2002爱思唯尔科技有限公司。保留所有权利。
An urban noise survey was conducted in the city of Caceres (Extremadura, Spain). In order to select the different points where measurements were to be taken, the streets were classified according to their use in communicating the different zones of the city. The four categories considered were all through roads (service roads were excluded): arterial roads outside the central zone, arterial roads in the central zone, other two-way roads connecting different zones, other one-way roads. The first two categories were found to be statistically indistinguishable, and together with the third had the highest noise levels-median Leq above 70 dB(A). The one-way roads were some 5 dB(A) quieter. Thus the sound levels in Caceres, a small city, are quite high, with 90% of our measurements surpassing an Leq of 65 dB(A) during working hours. Finally, relationships were established between the equivalent level, traffic flux, and the main noise level percentiles, with results in good agreement with those of other authors. We can also conclude that city noise can be usefully studied by classifying the streets according to their use. (C) 2002 Elsevier Science Ltd. All rights reserved.
