AB  - In an engineering context, objective evaluation of vibroacoustic models is traditionally performed with visual or numeric information. However, actual auditory perception cannot be transmitted through these types of objective representations. Sound Field Reproduction (SFR) of sound fields emitted by physical objects is often based on simplistic point source models with modified radiation properties or from recordings, using stereophonic or binaural techniques. In the perspective of better perceptual evaluation of engineered products, it would be useful if such methods would not be limited to certain types of sources, modeling techniques or predefined listening spots. A general SFR method using Wave Field Synthesis formalism applied to common vibroacoustic models as found in mechanical engineering is proposed. SFR applied to an analytical model of a harmonic or broadband excited plate is studied using three Secondary source distributions geometries. Results of numerical simulations illustrate the viability and limits of the approach.
