Product Code:SAE J2889
Title:Vehicle Sound Measurement at Low Speeds
Issuing Committee:Safety And Human Factors Steering Committee
Scope: The Vehicle Sound for Pedestrians Subcommittee of the SAE Safety and Human Factors Committee is developing a test procedure to determine the sound output of electric and hybrid-electric powertrain vehicles at certain low-speed conditions. Establishing a consistent method of measuring the sound output of these vehicles will facilitate further study into the need for additional measures to alert pedestrians to the presence of these vehicles in traffic. This test procedure could also become industry practice should it later be deemed necessary to record the sound output of certain vehicles in low speed traffic conditions where vehicles, pedestrians and other road users are co-mingled.
