    Tips: Sound level meter working principle

    The sound level meter uses a microphone to convert the sound into an electrical signal, and then a preamplifier converts the impedance to match the microphone with the attenuator. The amplifier adds the output signal to the weighting network, performs frequency weighting on the signal (or an external filter), and then amplifies the signal to a certain amplitude through the attenuator and amplifier, and sends it to the effective value detector (or external press Level recorder), give the value of the noise level on the indicator head.

    Sound level meter for accurate measurement
    The 50-meter construction site next door is being renovated. The noise level measured by this sound level meter during the day has reached more than 100. After closing the curtains at home, the test is about 50 or 60, and the measurement results are very accurate.
