Automotive interior acoustic testing and development environment

A method of testing acoustic performance of a plurality of sound transducers in a simulated vehicle passenger cabin, comprising the steps of:

• assembling a frame lattice defining a plurality of cavities around an interior space, wherein the frame lattice defines a door section radially movable for enclosing the interior space at a closed position and for providing ingress and egress to the interior space at an open position, and wherein the frame lattice is comprised of a plurality of vertical panels and a plurality of horizontal panels as a reconfigurable orthogonal grid adapted for adding and removing selected panels to modify a size and shape of the interior space and the placements of the cavities;
• mounting a plurality of transducer assemblies in selected ones of the cavities, each assembly having a faceplate mounting a transducer for acoustic coupling with the interior space;
• mounting a plurality of blank panels in other selected cavities to shutter the respective cavities;
• mounting a covering liner to an inner side of the frame lattice;
• and
• interconnecting the transducers with a signal processor;
• and
• reproducing audio signals exchanged between the signal processor and the transducer to simulate a corresponding configuration of the passenger cabin in a vehicle.
