FAQs

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 is the reason for the poor sound response of the burst sound level meter?

The sounds response of the burst sound level meter is caused by improper testing. For example, if the indication value does not drop during slow weighting and the test is started, the LASmax value will be too high. It is recommended to wait for 10s to restart the test.
