Active noise reducing headset-an overview Academic Article uri icon

abstract

  • Abstract Analogue active noise-reducing headset has been one of the most successful applications of active control of sound, with recent digital noise reducing headset promising even further improvement in performance and flexibility. This paper presents an overview of the active noise-reducing headset, from passive attenuation, through analogue feedback control to digital control. The effect of the delay introduced by the digital system on the performance with feedback and feedforward configurations is also discussed.
