Localization of Noise Sources in Large Structures Using AE

Description:

This paper describes application of AE monitoring techniques to localize the sources of large noises in civil structures. These noises occur during operation of moveable portions of a structure in such things as lift bridges and moveable sports stadium roofs. The use of straightforward AE monitoring techniques can provide clear...

Noise Localization via Acoustic Emission Monitoring on a Rolling Leaf Bascule Bridge

Description:

Acoustic emission (AE) testing was used to identify the source of audible “bangs” generated during opening and closing of a large, double-leaf rolling-lift bascule bridge. The data were analyzed using a combination of well-established AE techniques, including first hit analysis (FHA), planar location analysis, and linear location analysis. The FHA...
