Summary/Abstract: The subject of this paper is an experimental study on girder-borne sound pressure emission. The sources of the excitation are a hammer and a modal shaker. The struc-ture researched is a simply supported steel plate girder of the size: 7.95 m x 1.5 m. The study covers the acceleration and sound pressure level measurements (SPL), and SPL estimation based on the accelerations measured. The correlation factor for higher estimation accuracy in lower frequency bands is proposed.
