Passive and active noise reduction enable you to enjoy music even in noisy environments. 4 NoiseGard Advance The NoiseGard Advance active noise compensation system is based on the principle of cancelling out sound using "anti-sound" (phase-inverted sound). Tiny microphones pick up low-frequency ambient noise (up to 1 kHz) near the ear. The NoiseGard Advance electronics use this noise to generate a sound wave which is the exact opposite (IE: at the same level but polarity reversed ­ 180° out-ofphase), the effect being that the polarity reversed signal cancels most of the outside noise.
