Applications
A sound level meter is a device used to measure sound intensity. It is widely used in many fields such as environmental monitoring, industrial production, building design and construction, traffic management, occupational health and safety, etc. Measuring the sound intensity in different areas, helps planning departments understand and control urban noise pollution, and also provides data support for traffic planning and noise control. It is used to detect the noise generated by medical equipment during operation to ensure that the noise of medical equipment will not interfere with and harm patients and medical staff. It is used to detect the noise generated by fire-fighting facilities during operation to ensure that the noise of fire-fighting facilities will not interfere with and harm the surrounding environment and personnel. In times of crisis, it can promptly and effectively sound the alarm to guide people to escape.

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: Is The Higher The Sensitivity of The Sound Level Meter, The Better?
The higher the sensitivity of the sound level meter, the better. Instead, the appropriate sensitivity needs to be selected according to the actual measurement needs. The sensitivity of a sound level meter refers to the relationship between the change in the output signal of the sound level meter and the change in the input sound pressure. It describes the degree of response of the sound level meter to the change in sound pressure. It is an important performance parameter of the sound level meter and directly affects the accuracy of the measurement results. A highly sensitive sound level meter can capture subtle sound changes more accurately, thereby improving the accuracy of the measurement. However, different measurement tasks have different requirements for the sensitivity of the sound level meter. For example, in situations where extremely low sound intensities need to be measured, such as environmental noise monitoring or acoustic laboratory research, a highly sensitive sound level meter is a more appropriate choice because it can detect lower sound pressure levels. In some cases, a sensitivity that is too high may not be necessary and may even lead to unstable measurement results or introduce unnecessary noise.
