Abstract: The invention relates to a method of determining acoustic features of sound signals indicating the presence or absence of a property of the sound signal or sound generator, it also relates to the use of the result of this determination of features for analysing unknown sound signals as to the presence or absence of a certain relevant property or for modifying the sound generation with a view to optimizing a certain relevant property.

Abstract: The invention relates to a motor vehicle body, the support structure (10) of which is composed of large-size partial modules (12, 34, 50, 66), a basic module (12) comprising lateral longitudinal members (15) and a body floor (14) and reaching laterally as far as front wall columns (20), and, when the support structure (10) is assembled, the basic module (12) being connected to a front end module (34) which belongs to the front crumple zone of the motor vehicle and is supported in a crash stable manner on the basic module (12). In order to provide a motor vehicle body, in which the front end module (34) even without a roof construction is fixed in a sufficiently stable manner on the basic module (12), a front end region (36) of the body floor (14) belongs to the front end module (34) and extends rearward over a considerable length region of the basic module (12) between lateral longitudinal member sections (16).
