Device and method for measuring a talking quality of a communication link in a communications network (10). The device comprises measurement means (22; 31, 36) connected to the communication link, which are arranged to subject a degraded speech signal s'(t) with respect to a reference speech signal s(t) to an objective measurement technique for measuring a perceptual quality of means are arranged for producing a quality signal (q) which represents an estimated value concerning the talking quality degradation. The degraded speech signal comprises a returned signal r(t). The measurement means (22; 31, 36) are arranged to execute the objective effects in consequence of noise present in the returned signal. The objective measurement technique comprises the determination of a threshold noise level by determining a local minimum value of the degraded speech signal s'(t).
