Design of monitoring system for machines and equipment noise

Sound level meter is used for measuring unsteady noise of machines,however it is often unable to clearly display whether or not the noise is excessive at any time,and can't be manipulated in a distance.To solve the problems above,a monitoring system is designed,which includes a sound level meter,PC and series cable.The software for the system is base on MATLAB.The measurement data are transferred to the computer and displayed synchronously with the sound level meter.Meanwhile,the system will alarm when the measurement data exceed the limit value.The results of the trial run showed the system meet the design requirements.It can be expediently used to detect if the machine operation noise is excessive.
