7 Operational Steps of Noise Meter
1. Open the carrying case of the noise meter, take out the noise meter, and put on the sensor.
2. Put the noise meter in state A, check the battery, and then calibrate the noise meter.
3. Adjust the measurement range of the instrument according to the common environmental sound level scale.
4. Measurement: Fast (to measure the instantaneous value of an environment with a large change in sound pressure level), slow (to measure the average value in an environment with a small change in sound pressure level), pulse (to measure a pulsed sound source), filter ( Measure the sound level of the specified frequency band) Various functions are used for measurement.
5. Record the measurement data.
6. After the measurement is completed, it is recommended to check the sensitivity of the noise meter with an acoustic calibrator to ensure the accuracy and reliability of the measurement data.
7. Organize the equipment, disassemble the sensor and battery, and put them back in the designated place.

The noise meter is used for the sound level measurement of the environment, machinery, traffic, ships and other noises; the decibel meter and the classification of noise measurement mainly include the following types:
1. Noise meter can be divided into precision measurement, engineering measurement and noise census from the accuracy of measurement requirements.
2. The noise meter can be divided into steady-state noise measurement and unsteady-state noise measurement from the time characteristics of the sound source or sound field. Non-stationary noise can be divided into periodic noise, irregular noise and pulse sound.
3. The noise meter can be divided into broadband noise, narrowband noise and noise containing prominent pure tone components from the frequency characteristics of the sound source or sound field.
4. Noise meter can be divided into precision measurement, engineering measurement and noise census from the accuracy of measurement requirements.
