Does acoustic emission testing require a quiet/silent lab?

Acoustic emission testing (AET) does not necessarily require a quiet or silent lab, as it specifically focuses on capturing and analyzing signals generated by structural changes or failures in machinery and infrastructure. Unlike other testing methods that rely on external excitation, acoustic emission testing can be conducted under normal operating conditions. The monitoring system, including AE sensors and related products, is designed to detect and analyze acoustic signals produced during the operation of various structures such as bridges, storage tanks, valves, and rotating machinery, enabling real-time condition monitoring.

While some acoustic emission applications may benefit from controlled environments with lower background noise levels, such as laboratory settings for research purposes, the primary objective of acoustic emission testing is to capture and analyze the specific signals related to the structural integrity of the monitored system. Therefore, the focus is on the ability of the monitoring system to discriminate relevant acoustic emission events from background noise, rather than complete silence in the testing environment.
