A Method For Modeling Nonharmonic Periodic Acoustic Radiation from a Loudspeaker
In the past most of the work on the problem of determining the acoustic field radiated by a loudspeaker, or similar structure, has concentrated on the harmonic problem [1,2,3,4,5,6,7,8]. This has the advantage that the frequency domain problem is essentially a purely boundary value type problem and methods exist for its efficient numerical solution. However, in many situations the radiation is either periodic but not harmonic, or transient.
