Abstract

An arrangement and method for assessing the audibility and annoyance of at least one distortion component dn(t) with n=1, . . . , N in the output signal p(t) of a device under test, by generating a virtual auralization output signal pA(t) at the output of an auralization system. The output signal pA(t) contains the distortion component dn(t) at an adjustable magnitude according to a scaling factor Sn provided from a control input, and is supplied to a perceptive model and to a reproduction system used by a listener. The auralization system receives the distortion component dn(t) from a separator which receives a test signal xT(t) from the output of a microphone and a reference signal xR(t) from a reference system.
