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...
