The objective of the present study was to assess the influence of noise, infrasound and temperature on performance and wakefulness of drivers performing realistic driving tasks in a simulator, where they were exposed to realistic and controlled environmental as well as driving conditions. Forty-eight young, healthy individuals 'drove' the VTI driving simulator for about four hours. They were exposed to different combinations of noise, infrasound and temperature. Two levels of each of these variables, representing low and high levels measured in real traffic, were used. The experimental design thus included eight different experimental conditions (combinations) with six drivers exposed to each condition. As dependent measures of driving performance the authors used steering precision, speed holding and stimuli-induced reaction time, while EEG, ECG and EOG were recorded for the assessment of wakefulness. Audiometry was carried out, before and after exposure, to observe possible temporary hearing threshold shifts.
