摘要
根据PCM语音编码技术和多媒体个人计算机及其声卡的优良特性 ,提出了噪声监测与分析的新办法 ,编制了基于VisualBasic 6 .0的噪声频谱分析软件 ,可以方便地对设备运转噪声进行频谱分析。与专用噪声分析仪器相比 ,本法具有成本低。
Based on PCM coding technology and strong multi-media and PC's function and their excellent sound card's performance, the new method for inspecting and analyzing the noise is put forward and the noise frequency analysis software is compiled, so that the frequency analysis of the equipment's noise can be carried out conveniently. Compared with the special instrument, it is cheaper and easy to expand relative function.
