摘要：
In this paper, based on analysis of the limitations of original design of noise measuring apparatus, an new Acoustic Vibration Analyzer (for short, AVA) is introduced, which employs ARM based controlling techniques of sampling and displaying and DSP techniques of signal processing with high speed A/D sampling. It has integrated several functions of frequency spectrum analysis, vibration analysis, noise data measuring and etc. Then principle and design method of the Acoustic Vibration Analyzer is introduced in detail. Finally. as a result, the functions and the precision of the Acoustic Vibration Analyzer conform to the international standards of IEC61672-2002 and the apparatus has perfectly met the domestic demand of unsteady noise meaSUring.
