现场用磁带机记录声强探头取得的两路声压信号,到实验室回放、送入分析系统进行声强处理,这种声强测量方法对利用现有仪器设备有很大灵活性,对于发展噪声控制工程具有实际意义.然而,用这种方法进行声强测量有许多技术上的细节需要慎重对等,方能取得良好结果. The scene with a tape drive to record two sound pressure signals obtained by the sound intensity probe to the laboratory playback, into the analysis system for sound intensity processing, this sound intensity measurement method has great flexibility on the use of existing equipment, for the development Noise control engineering is of practical significance, however, there are many technical details of sound intensity measurements that require careful equivalence in order to achieve good results.
