The Sennheiser PXC 550-II is one of the highest-scoring headphones in our ratings, with superb sound quality and noise canceling. The PXC 550-II is as much as $300 cheaper than many competitors.
Simplified graphical depiction of active noise reduction. To cancel the lower-frequency portions of the noise, noise-cancelling headphones use active noise control.A microphone captures the targeted ambient sounds, and a small amplifier generates sound waves that are exactly out of phase with the undesired sounds.
Active noise cancellation technology (also known as ‘ANC’) is now a common feature in over-ear headphones, and increasingly smaller in-ear models (like wireless earbuds) too. While it adds a ...
The hot headphone feature of the 21st century is active noise canceling, otherwise known as ANC. Flip a switch (or press a button), and the earpieces magically reduce a certain range of ambient ...
Active noise canceling is best suited for low frequencies. For higher frequencies, the spacing requirements for free space and zone of silence techniques become prohibitive. In acoustic cavity and duct-based systems, the number of nodes grows rapidly with increasing frequency, which quickly makes active noise control techniques unmanageable.
Electronic microphones, circuitry, and receivers perform active noise reduction, also known as noise-cancelling, in which a signal that is 180-degrees out-of-phase of the noise is presented, which in theory cancels the noise.
