Abstract:
1. An arrangement for assessing the audibility and annoyance of at least one distortion component d n (t) with n=1, . . . , N in the output signal p(t) of a device under test receiving an input signal u(t), by generating a virtual auralization output signal p A (t) containing said distortion component d n (t) at an adjustable magnitude according to a scaling factor S n , characterized in that said arrangement comprises: a nonlinear model using linear and nonlinear parameters of said device under test, having an input provided with the input signal u(t) and having an output generating a multitude of state signals in a state vector x which describes the state of said device under test in the small and large signal domain; a linear model using linear parameters of said device under test, having an input provided with the input signal u(t) and having an output generating a multitude of linear state signals in a state vector z an auralization system having a first input supplied with the input signal u(t), a second input provided with the state vector x from the output of the nonlinear model, a third input provided with the state vector z
