What are the advantages of noise and dust monitoring systems?

1) Measuring instruments. All measuring instruments should comply with the appropriate standards and must be calibrated before use. When measuring the noise level, a precision and ordinary sound level meter is used, and if the noise spectrum is to be measured, a filter needs to be worn on the sound level meter; When measuring equivalent sound levels, an integral sound level meter is used; Impulse noise is measured using a pulsed sound level meter; Sound intensity meters, real-time analyzers, etc., are used to measure sound intensity or analyze noise signals.

2) Measurement conditions. The effect of background noise should be taken into account in the measurement. When the measured noise is less than 10db higher than the background noise, the measurement results should be corrected according to the regulations; When the measured noise is less than 3dB above the background, the measurement results cannot be used as any basis, only as a reference.

When the wind speed is greater than level 4 in ambient weather, outdoor measurement should be stopped. When measuring, avoid high temperature, high humidity, strong magnetic fields, ground...
