The increasing availability of Electric Vehicle (EV) models in the market raises questions about customers’ expectations regarding interior acoustic comfort. Uncertainty exists regarding reactions to the tonal components of electric powertrain noise and how expectations may adapt to lower interior noise levels. Motivated by these considerations, Autoneum and HEAD acoustics collaborated on a study to develop Sound Quality metrics that assess perceived NVH quality in EVs, with special emphasis on tonal noises. The study involved 14 vehicles under different operating conditions, representing various contributions from electric powertrains and tire noise. This article presents the study’s methodology, results, and a comparison between the newly developed Sound Quality metrics and traditional metrics (SPL, AI) for evaluating NVH quality in EVs. Furthermore, the application of these metrics to assess the impact of passive treatments on acoustic quality in a Battery Electric Vehicle is discussed with one example.
