Claim:
1. An apparatus for improving a perceived quality of sound reproduction of an audio output signal, comprising: an active noise cancellation unit for generating a noise cancellation signal using an environmental audio signal as an input, wherein the environmental audio signal comprises noise signal portions, the noise signal portions resulting from recording environmental noise, a residual noise characteristics estimator for determining a remaining noise estimate depending on the environmental noise and the noise cancellation signal, a perceptual noise compensation unit for generating a noise-compensated signal based on an audio target signal and the remaining noise estimate, and a combiner for combining the noise cancellation signal and the noise-compensated signal to acquire the audio output signal, wherein the residual noise characteristics estimator is arranged to receive the environmental audio signal, wherein the residual noise characteristics estimator is arranged to receive the noise cancellation signal from the active noise cancellation unit, and wherein the residual noise characteristics estimator is configured to determine the remaining noise estimate using the environmental audio signal and using the noise cancellation signal.
