家庭安防系统中声音信号的小波分析与降噪

摘要

在LabWIEW环境下,针对家庭安防系统所采集的声音数据进行了小波分析与降噪研究,通过试验较好地实现了现场声音采集和去噪处理系统运行表明,采用小波降噪方法达到了理想效果,在人的听觉范围内既没有感觉到噪声,又无失真现象.%sound data collected by the safety precautions system based on LabVIEW were analyzed and tested to denoise. Using wavelet denoising with adaptive parameters selected by experiments, the system achieved desired results. Within auditory range we haven't heard noise and distortion.
