(57) 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.
