摘要：

An empirical investigation of the errors in urban and transportation noise descriptors caused by the use of automatic monitoring sampling techniques is presented. Using eighteen selected 'continuous' 24-h digital recordings of traffic noise, the common descriptors were computed for comparison with those computed from data sampled from the same recordings in a manner simulating the digital and analogue automatic monitor sampling techniques by appropriate omission of data during analysis. Different time combinations for the digital sampling approach and different combinations of record time to non-record time for the analogue sampling approach were simulated. The discrepancies between the values of the descriptors from the 'sampled' data and those from the 'continuous' data are presented in graphical and tabular from and should serve as a guide to potential and current uses of automatic monitors as well as indicating the probable accuracy of past studies. © 1979.
