摘要:
针对使用声音测量设备对家庭影院音响系统检测时噪声信号多的问题，建立了一种音响性能分析系统.首先利用振动计测量音响产生的振动信号，然后用数据采集卡采集该振动信号和函数发生器发出的标准信号，最后由软件进行信号分析，完成对音响性能的检测.该系统以振动计、任意函数发生器、NI数据采集卡、计算机为主要硬件平台，用LabVIEW图形化编程语言编写仪器控制、数据采集、数据存储、信号分析等软件程序，实现了多通道信号的实时数据采集、在线监测、数据存储、信号分析等功能.实验结果表明该系统能准确测量音响的振动频率、幅值大小，并对音响的振动信号进行频率校准、功率谱分析、相关性分析以及频响函数分析等；该系统测量精度高、实时性好，测量所得信号噪声小，测量分析结果能反应音响的基本性能.该系统组建简单方便，适合家庭影院音响系统的性能测试.
Abstract:
A system which can collect vibration signals for audio performance analysis was specially proposed to solve the problem that lots of noise may occur when sound measurement equipment is used to detect an audio system. To detect the audio performance, firstly, vibration meter was used to measure the vibration signal generated by audio, then the data acquisition card acquired the vibration signals and the standard signals produced by function generator, finally both of the two signals were analyzed by software to finish the measurement. The vibration meter, arbitrary function generator, NI data acquisition card and computer were used as the system’s main hardware platform. The programs of instrument control, data acquisition, data storage, and signal analysis were developed by graphical programming languageLabVIEW, achieving the realtime multichannel signal data acquisition, online monitoring, data storage, signal analysis and other functions. Experimental results show that the system can accurately reflect the variations of the audio’s vibration frequency, amplitude, it can also analyse the audio vibration signals’ frequency calibration, power spectrum analysis, correlation analysis, and frequency response function analysis; the system has high accuracy, good realtime and low noise generated by measured signals, the basic properties of audio can be reflected by the test. It is found that the system can be set up simply conveniently, and which is suitable for home theater sound system performance test.
