实际监测中稳态和非稳态噪声源监测方式的探讨

Discussion on Monitoring Methods of Steady and Unsteady Sound Sources

为达到了解环境监测系统噪声监测仪器的性能。通过比对试验对稳态和非稳态声源进行了监测。结果表明各仪器对稳态噪声源的监测结果差异很小,对非稳态噪声源监测结果存在较大的差异;差异主要由仪器间的系统差异造成;通过试验充分了解各仪器性能,为今后稳态和非稳态声源的实际监测提供科学依据。

In order to understand the performance of the instruments of environment noise monitoring system,the comparison test has been done on steady and unsteady sound sources. The results show that the differences among the instruments are very small on the steady noise,while there are quite big differences among the unsteady noise monitoring results. Differences are mainly caused by system differences among instruments.Through experiments performance of each instrument is fully understood, a scientific basis is provided for steady and unsteady sound sources monitoring.
