With the advent of more stringent external noise legislation and the demand for lower interior noise levels, vehicle manufacturers are under increasing pressure to reduce the emitted noise from their engines. This paper describes a combined analytical and experimental approach that allows the designer to optimise the effects of possible modifications, such as increase of stiffness, damping or mass, on structure borne noise, without recourse to a series of expensive hardware changes. To demonstrate the application of this approach samples are given of engine system models obtained from mathematically combining either the measured or calculated dynamic characteristics of the engine component parts.
