摘要：
An apparatus for improving a perceived quality of sound reproduction of an audio output signal is provided. The apparatus comprises an active noise cancellation unit (110) for generating a noise cancellation signal based on an environmental audio signal, wherein the environmental audio signal comprises noise signal portions, the noise signal portions resulting from recording environmental noise. Moreover, the apparatus comprises a residual noise characteristics estimator (120) for determining a residual noise characteristic depending on the environmental noise and the noise cancellation signal. Furthermore, the apparatus comprises a perceptual noise compensation unit (130) for generating a noise-compensated signal based on an audio target signal and based on the residual noise characteristic. Moreover, the apparatus comprises a combiner (140) for combining the noise cancellation signal and the noise-compensated signal to obtain the audio output signal.
