Vibro-acoustical comfort in cars at idle: human perception of simulated sounds and vibrations from 3- and 4-cylinder diesel engines

Parizet, Etienne / Amari, Mael / Nosulenko, Valery

A bench was used to reproduce the vertical vibrations of the seat, the vibrations of the steering wheel and the noise measured at the driver's ears of cars running at hot idle. In a first experiment, subjects were only submitted to seat vertical vibrations; it appeared that comfort could be described by rms values of signals, without using ISO-2631 weightings. In a second experiment, subjects were submitted to all stimuli; the analysis of free verbalisations could explain the perceptual dimensions and were helpful for identifying the contribution of noise and vibration stimuli to overall comfort.
