A Blaupunkt innovation: DNC
Pure, unadulterated sound
While the vehicle is in motion, a signal processor uses a microphone to measure and analyse the driving noise (interference signal) that covers the music reproduction (desired signal) in the bass frequency range in particular. This problem is compensated by specifically boosting the audio signal in the corresponding frequency range.
As a result, DNC keeps the sound and the volume at a constant level, independent of the driving speed and road conditions: driving noise covering that would not be possible with conventional, wideband volume control.
