Simulation of Horn Driver Response by Direct Combination of CD Frequency Response and Horn FEA
Today a horn driver developing is still time and cost consuming. In addition compression driver behavior depends by the horn profile. In this study is proposed a new technique to model a combination of an existing compression driver and a virtual horn, in order to predict the horn driver acoustic behavior. This procedure comprises compression driver measurement on a Plane Wave Tube and horn acoustical FEA model. COMSOL Multiphysics® is used to simulate horn acoustic pressure with a plane wave condition in the horn throat. COMSOL data was exported and post-processed with driver real measurement. A new equation is presented, correlating measurement and simulation, to obtain on-axis absolute sound pressure level of the horn driver frequency response.
