This paper describes a new approach to the analysis of vehicle noise with impulsive characteristics such as that emitted by diesel engines. The technique provides an objective measurement that is strongly associated with the subjective response to impulsiveness in the external noise of vehicles. Information is obtained which describes the level of impulsiveness as a function of frequency in octave bands. A method of deriving a single figure index which combines the effects of impulsiveness and overall level is suggested.
