Abstract (en)

Procedure for the optimisation of the acoustic quality, comprising the steps of arranging media (1) for playing a recorded sound or for synthesising an artificial sound, manipulating (2, 3) the sound thus generated so to confer a predefined value of at least one psycho-acoustic parameter, such as, for example, roughness, loudness, sharpness or impulsiveness, subjecting the sound thus manipulated to the subjective judgement of a plurality of panels of statistically representative experimental individuals, processing the subjective evaluations of the panels, in association to the psycho-acoustic parameters conferred to the sounds which are the object of the evaluation, in such a way to identify optimisation values of the perceived sound quality. In the case of application to the sound perceived inside the passenger compartment of a moving motor vehicle, sound processing media are arranged inside the motor vehicle for conferring optimal values of one or more previously defined psycho-acoustic parameters to the perceived sound. <IMAGE>
