Default unsteady pressure and acoustics
Posts: n/a
Hi, I have a simple general question about unsteady pressure and acoustics. If I have unsteady pressure on the surface body, say p(x,t), (it's not p'(x,t)), how can I calculate the sound field radiation? Is that by Fourier transform? or you need to integrate the unsteady pressure as a sound source to calculate the radiated sound? many thanks.
