Dolby has developed a proprietary noise suppression technology commonly referred to as Active Noise Cancelation or ANC.  Our approach with Dolby Dimension was to create a synergy between noise suppression, LifeMix, and a spectacular overall user experience.  Dolby Dimension actively listens to external noises and applies Dolby developed algorithms to reduce those deemed undesirable from reaching the listener.  With Dolby Dimension, we aimed for an implementation that complements the immersive experience of Dolby Dimension.
