| Abstract | The Pedestrian Safety Enhancement Act of 2010 requires the National Highway Traffic Safety Administration to conduct a rulemaking to establish a Federal Motor Vehicle Safety Standard requiring an alert sound for pedestrians to be emitted by electric or hybrid vehicles. The goal is to establish performance requirements for an alert sound that allows blind and other pedestrians to reasonably detect a nearby electric or hybrid vehicle. This report documents the analysis of acoustic data for a subset of vehicles measured on hemi-anechoic chambers equipped with a chassis dynamometer. The analyses include data for electric, hybrid, and internal combustion engine vehicles. Ambient noise, measurement repeatability (run-to-run), and measurement reproducibility (site- to-site) are examined. The analysis also includes a limited comparison of indoor and outdoor testing. Indoor test data was provided by Transport Canada. NHTSA’s Vehicle Research and Test Center (VRTC) and the Transportation Research Center (TRC) provided outdoor test data for this analysis. |
