| Abstract: | The fan noise at work was carried out tests by the software LMS Testlab,getting the fan noise spectrum;the fan noise reduction was predicted by using of LMS TestLab Sound Diagnosis module for collecting real-time signal,providing the basis for the latter part of noise control.To avoid the blindness of the noise control,more economical. |
