摘要

为了能够实时监测城市区域环境噪声

依据GB/3096-93声环境质量标准

开发了一种基于LabVIEW的新型环境噪声自动监测仪.以声压传感器和PC机为硬件基础

应用虚拟仪器技术

实现了传统仪器功能的高度集成

实现了面板输入控件和显示控件合理布局.仪器可以在25~138 dB测量范围内实现±1.5 dB的精确度和0.1 dB的分辨率;实时检测并记录周围环境的声级、瞬时声级、连续等效声级、最大和最小声级;图形化实时显示噪声的时域波形和频谱;自动实现环境声级超限报警并记录相关数据.

Abstract

For the purpose of measuring environmental noise of urban area at any moment

a new kind of virtual environmental noise automatic measuring instrument has been developed based on the LabVIEW.This design is according to GB3096-2008 environmental quality standard for noise.The hardware system is based on sound pressure sensor and personal computer.With the application of the virtual instrument technology

high integration was realized for the functions of the traditional sound level meter by software.The layout of controls and indicator in front panel is rational.The measure range of this instrument is from 25 dB to138 dB

with the accuracy of ±1.5 dB and the resolution of 0.1 dB.Using the VI

it can be measured and noted that the ambient noise dB(A) level

the transient dB(A) level

equivalent continuous dB(A) level and the maximum and minimum dB(A) levels at any moment.The VI can real-time display the ambient noise signal waveform and frequency spectrum.At the same time it can give the alarm when the dB(A) level state exceeds standard automatically and recode the correlation data.
