Abstract
In some cases it is important to be able to measure not only the total sound intensity on a panel surface in a vehicle cabin, but also the components of that intensity due to sound radiation and due to absorption from the incident field. For example, these intensity components may be needed for calibration of energy flow models of the cabin noise. Two different methods are introduced in the present paper: one based on surface absorption coefficient and one based on surface admittance. The two methods are compared in terms of underlying assumptions and through simulated and real measurements. The method based on absorption coefficient appears to be the more robust.
