DEVICE AND METHOD FOR IMPROVING PERCEIVED QUALITY OF SOUND REPRODUCTION BY COMBINING ACTIVE NOISE CANCELLATION AND COMPENSATION FOR PERCEIVED NOISE Russian patent published in 2017 - IPC G10K11/178 

FIELD: physics.

SUBSTANCE: device includes an active noise cancellation module (110) for generating a noise cancelling signal based on an ambient audio signal, wherein the surrounding audio signal comprises portions of the noise signal, wherein the noise signal portions are the result of recording ambient noise. In addition, the device comprises a residual noise performance estimation module (120) for determining the residual noise characteristic, depending on the ambient noise and the noise cancellation signal. In addition, the device comprises a sensed noise compensation unit (130) for generating a noise-compensated signal based on the target audio signal and based on the residual noise characteristic. In addition, the device comprises a combining unit (140) for combining a noise cancellation signal and a noise compensated signal to produce an audio output signal.

EFFECT: improving the perceived quality of sound reproduction by combining active noise cancellation and compensating the perceived noise, by improving the perceived quality of sound reproduction through headphones.
