Noise testing enterprise standard formulation

Many manufacturing enterprises have problems with acoustic noise in product design, but do not know how to detect the problem point and do proper measurement and comparative analysis.Thunderstar anechoic technology,Inc. has accumulated a lot of experience in acoustic measurement methods, which can help clients to design appropriate noise testing enterprise standards for their products.

The main content is divided into the following five items, test equipment, test conditions, test criteria, sampling methods and report content.Detailed description is as follows：

The location and distance between the microphone and the product under test will be determined according to ISO, GB and the corresponding industry product standard. 

Appropriate test conditions can reflect the noise performance of the product under normal use conditions. Standby mode and operating mode are the two main test conditions specified in ISO, GB and corresponding industry product standards. .Thunderstar anechoic technology,Inc. can provide the appropriate test conditions for the tested products based on our extensive testing experience to obtain real acoustic data in line with actual usage.

The test criteria are used to define the acoustic problem of the product or compare the sound quality differences of the same type of product. There are many parameters that can be used to determine the product noise performance, among which weight sound pressure value, loudness and sharpness are the main parameters.

Statistical methods will be imported into the test data analysis to exclude the deviation caused by different component or assembly differences in the same series of products. And different types of products have different sample sizes.
