Acoustic Transmission Loss and Structureborne Noise Transmission Tests on a LASCOR and a Reference Steel Panel

Abstract

LASCOR is a laser welded corrugated steel sandwich developed as a lightweight construct for ship superstructures. Tests were performed to measure acoustic transmission loss and structureborne noise transmission for both a LASCOR panel and a reference conventional rib-stiffened steel panel. This report outlines the test methods used and compares the results for the two panels. LASCOR, Laser Welded Corrugated Steel, Sandwich, Sound Pressure, Driving Point Mobility
