Classification of noise meters
Noise meter is also called sound level meter, decibel meter, noise meter. Mainly used to test the noise of the environment and machines.
According to the structure, it is divided into one-piece and split-type. At present, most of the noise meters on the market are all-in-one, which is more convenient for measurement.
According to the function, it is divided into ordinary type and multi-function type.
The ordinary type is mainly used to test the noise of production workshops, offices, and machines. It has A\C weighting and can check the maximum and minimum values during the test. There is no data storage and printing, computer transmission and other functions. The test range is generally 30-130DB. It has the characteristics of small size, easy to carry, simple operation and low price.
The multi-function noise meter is generally used in high-requirement test occasions, such as low decibel test (HS5661A can test 20dB), high decibel test (HS5661B can test 160dB), can store data, can be connected to a micro printer, and can be used with a computer. Connect and convert test data into graphics, can test noise online, can test parameters such as Lp, Leq, Le, Lmax, Lmin, Lx, Lpeak, Lcpeak, Lceq, Ltm5, L10, L50, L90, L95, and many more Channel noise test, noise spectrum analysis, etc.
