This paper describes the analytical method of radiated noise from cylinder block and oil pan. Oil pan was modeled using the Ross-Kerwin-Ungar model and the virtual mass method for damping steel sheet and lubricating oil. The cylinder block and oil pan models were combined by the BBA method. Calculated noise agreed well with the measured one.
