In the design of loudspeaker, the sound field characteristic is a particularity consideration. The aim of this work is to present a numerical technique named here the Convolution Method for the simulation of sound pressure field radiated by a loudspeaker which can be represented by the simple concept of vibrating rigid piton located in a baffle. The loudspeaker excitation can be either continuous wave (CW) or pulsed wave (PW). Numerical results of normalized contours surface map of acoustic pressure field are shown.
