    Q1: What is a noise detector?
    A1:  Noise tester is an instrument used for noise detection and testing in public places such as work sites and squares. Factory noise monitoring Noise pollution is one of the environmental pollutions that have a greater impact. Higher decibel noise can even cause serious damage to people's eardrums and cause deafness. The application of the noise tester can provide the decibel that the noise reaches in order to take relevant measures to control and reduce the noise. The measurement unit of the sound level is decibels. The professional noise tester has a highly sensitive sensor, high accuracy, and a wide range of applications. It can be widely used for noise measurement in various environments. Sound level measuring instrument, collectively referred to as sound level meter.

    Q2: Sound level meter working principle
    A2: 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.

    Q3: How big is the decibel scale?
    A3: Sound is measured in decibels (dB). Whispering is about 30 decibels, normal conversation is about 60 decibels, and motorcycle engines run at about 95 decibels. Noise above 70 decibels for long periods of time may begin to damage your hearing. Loud noises above 120 dB can cause immediate damage to your ears.

    Tips: What causes the digital display sound level meter time counting power is small?

    • Wrongly using the starting signal to directly subtract the first falling signal, applying the difference between the falling signals.
    • The display value jumps 0.5 seconds refresh frequency misuse for 1 second.

    Basic Sound Level Meter with Clear Display
    The device is relatively simple to operate, and the digital display provides clear readings. However, the device lacks advanced features that some other sound level meters offer.

    Clear and accurate readings
    The meter's accuracy has been spot-on, providing real-time readings that I can rely on. Its compact and portable design allows me to take it anywhere, and the user-friendly controls make it a breeze to operate. The durable construction assures me of its longevity, making it a wise investment for the long run.

    Great for my bands
    I am the sound guy for two bands and this device saves me from having to argue with band members. I balance the backstage sound in minutes and this sound level meter is the authority and afterwards I can easily adjust the back stage monitors.
