Everything that the NVH Simulator technology can achieve for interior vehicle sound can be applied to exterior vehicle sound. Assess multiple sound options back to back. Change the ambient level of environmental sound. Change the amount and content of traffic, including the sound generated by the other vehicles. Adjust sound levels, apply filters to change the sound character, a/b compare changes, all in real-time. The full suite of Jury Evaluation tools in the NVH Simulator can be used with Exterior Sound Simulator assessments to capture customer and stakeholder preference.
