摘  要:
采用Visual C++2008强大的编程功能开发噪声检测系统,并对大量样本音频文件频谱图进行比对,逐步分析出合格与不合格产品的音频频谱特征。同时,区别合格产品与不合格产品的频谱判断区间,最后提出噪音率临界值作为划分产品合格与不合格的一个判断依据,对于噪声检测具有一定的参考价值。

摘  要:
The noise detection system that is developed with Visual C + + 2008 tool compares some the sample of audio files,it steply analysis of audio spectrum characteristic of qualified and unqualified products,and it gets the difference between qualified products with substandard product. Finally,it proposes a noise rate value that is a judgment to qualified and unqualified product,which has a certain reference value for the noise detection.
