    Tips: How to use a sound level meter?

    1. The choice of the environment where the sound level meter is used: Choose a representative test site. The sound level meter should be off the ground and away from the wall to reduce the additional impact of the reflected sound from the ground and the wall.
    2. Weather conditions require that the sound level meter should keep the microphone diaphragm clean when there is no rain or snow, and a wind cover must be added to the wind above level three (to avoid wind noise interference), and the measurement should be stopped for strong winds above level 5.
    3. Open the sound level meter carrying case, take out the sound level meter, and put on the sensor.
    4. Put the sound level meter in the measurement state, check the battery, and then calibrate the sound level meter.
    5. Compare the table (reference for common environmental sound levels) and adjust the measurement range.
    6. The following can use fast (measure the instantaneous value of the environment with large changes in sound pressure level), slow (measure the average value in the environment with little change in sound pressure level), pulse (measure pulse sound source), filter (Measure the sound level of the specified frequency band) various functions for measurement.
    7. Record data as required, and it can also be connected to a printer or other computer terminals for automatic collection. Organize the equipment and return it to the designated place.

    Awesome dB Meter
    The recommended sound level meter, I found a lot of noise testing instruments, and finally decided to buy this one. This is a professional decibel meter with data retention, relative value average, and steady-state noise. Colleagues in the engineering department are all said it was good.
