Under the sponsorship of the U.S. Air Force and the FAA Engine Titanium Consortium, models have been developed which endeavor to predict characteristics of the backscattered micro-structural noise observed in focused-probe pulse/echo inspections of titanium billets and forgings [1–5]. In this paper we briefly review the history of the model development work at Iowa State University, and then compare noise model predictions with experiment for several cases of interest
