Sound pressure level measurement service
The sound pressure level is the most important and basic measurement item in the acoustic test. The purpose is to measure the sound of the object to be tested, in dB, or the weighted sound pressure value such as dB(A). The company provides complete sound pressure level measurement services, as well as free test results consultation, and can provide a complete test report in line with CNAS content.
The test environment has ultra-low background noise Lgn
According to the ISO and GB specifications, if the noise value Lp of the object under test is close to the background noise value Lbgn, the data cannot be determined as the noise of the object under test. Therefore, it is necessary to create an environment with a lower background noise value (namely the background noise value Lgn). The background noise level (i.e., background noise level Lgn) of our precision acoustic laboratory is guaranteed to be satisfactory.
The company’s precision acoustic laboratory and equipment for measuring sound pressure are in compliance with ISO and GB requirements. In order to simulate the site conditions of users,the acoustic environment of free or semi-free sound field should be built.The actual background noise value of our precision acoustics laboratory can be as low as 6~8 dB(A) by using precision instruments. Therefore, the sound pressure level measurement of general objects under test can be satisfied.
Comprehensive testing service
Our company has the ability to test for you whether it meets the ISO and GB testing standards or the self-set testing specifications.
Test results and acoustic solutions consulting
We not only provide accurate test reports conforming to CNAS content, but also provide free reference acoustics solutions, such as what causes noise in a certain frequency band, etc. In addition, if the client has any questions related to acoustics, such as basic acoustics, sound psychology, vibration, wave mechanics and other acoustic-related theoretical and practical problems, our company has professional engineers to serve for you, so as to help the client solve the problems related to sound.
