| Abstract: | This article analyzed different reason for the amplitude attenuation of the acoustic emission, and used the AE testing device produced by PAC America to test the acoustic emission attenuation using a pipe with many complex features. Then it draw a conclusions that different pipes feature weaken the acoustic emission signal in different ways. At last, some relevant recommendations were put forward. |
| Keywords: | AE(Acoustic Emission) detect pipe amplitude attenuation |
