The interior acoustic field of an automobile cabin

The acoustic field in an automobile cabin can be calculated using a Green’s function method. A method for calculating the acoustic field of an arbitrary volume bounded by an arbitrary surface is shown. The eigenvalues of the system, including the effects of arbitrary shape and surface impedance, are found. Alternatively, the acoustic response is calculated when one or more of the surfaces is in vibration without first calculating the eigenvalues. The method works equally well in one, two, or three dimensions.
