dc.description.abstractAn Exterior Sound Simulator (ESS) is a new tool for evaluating automotive exterior sounds in a virtual environment. These virtual environments can replicate real-world environments where a pedestrian is likely to interact with a vehicle. Thus, they can provide a more realistic context than conventional laboratory listening methods, whilst providing more experimental control than in conventional on-road evaluations. Therefore, ESS combines the advantages of the traditional laboratory listening test and on-road evaluation methods, but has very few of their limitations. However, to be a successful evaluation tool this simulator needs testing for its external validity. This paper describes a study that compares evaluations performed in a real-world environment and in a replicated virtual environment using an ESS. Fourteen participants evaluated an electric car in both these environments. The visual scenario represented a pedestrian standing at a residential road junction while the car, situated behind the pedestrian on the adjacent parallel road, travelled towards them at 12 mph. The car arrived at the junction at one of two different times. Three potential sounds from a vehicle manufacturer were compared by measuring the vehicle’s detection distance, evaluation of the vehicle sounds as recognisable and detectable, and through evaluation of the car as being powerful and pleasant. ANOVA at an alpha level of 0.05 showed no significant differences between the results obtained from the virtual and real-world experiments for the subjective evaluations of detectability, powerfulness and pleasantness. Thus, subjective evaluations of detectability and emotional characteristics of vehicle exterior sounds using the ESS’ virtual environment can be generalized to a similar real-world situation.-
