| 摘 要： | 本文提出利用美国NI公司的LABVIEW软件和计算机声卡采集声场信号并对其进行处理的方案.比较了计算机声卡和数据采集卡(DAQ)之间的优缺点,发现PC机配置的声卡即可构成实时、高信噪比的声场数据采集系统.该应用可以推广到语音识别、环境噪声监测等多种领域,同时该方案对其他低频信号分析具有指导意义.

| Abstract: | In this paper, a method that sound signal can be acquired by the sound card in computer and be processed by the LabVIEW software is brought forward. Compared the sound card with the DAQ (Data Acquisition), it is found that a real-time and high SNR(Signal Noise Ratio) sound signal acquisition system can be designed using the sound card in computer. The application can be used widely In the field of Sound Identifying, Environment Noise Watching, and so on. And this method can be used to analysis the other Low Frequency signal. |
