According to ISO3745-2003, IEC 60312, GB6882 and ISO7779, GB/T4214.1, GB/T4214.4, GB/T3767, we design the anechoic chamber. The acoustic parameters in 

The design include background noise, cut-off frequency, available space, vibration reduction, etc. 

Under the premise of meeting the acoustic index, the design of the testing room takes into account the wiring, monitoring conditions, indoor environment and so on

Related technical parameters  :

1. 6-10 points synchronous data acquisition

2. In Windows environment, using professional noise testing software, the noise source analysis, identification and noise source characteristic analysis are carried out by computer

3.The noise of the tested products can be recorded, and the parameters and test results can be classified and archived automatically

4.It can be used to measure the noise and analyze the modal when the product is running

5.According to the comprehensive analysis of the mechanical parameters, electrical parameters, noise parameters and other parameters of the product in the running state, we can effectively judge whether the product is qualified or not

6.It can test the vibration of the product and record the corresponding data, automatically generate the curve chart, statistical report, etc.
