Noise and vibration transmission in motor vehicles is difficult to study due to the complexity of the vehicle structure and noise sources. Many noise sources can cause problems at higher frequencies, say above 250 Hz. At these frequencies Statistical Energy Analysis (SEA) can be used to study noise transmission. In this work SEA modelling is discussed. Ways of calculating power input to the vehicle are shown and measured and predicted sound pressure levels for the engine running are compared. The aim of the work is to find a simple method of estimating the power input to the vehicle and subsequently predict the sound pressure level in the saloon.
