Noise-cancelling headphones specify the amount of noise they can cancel in terms of decibels. This number may be useful for comparing products but does not tell the whole story, as it does not specify noise reduction at various frequencies.
Graphical depiction of active noise reduction. Active noise control (ANC), also known as noise cancellation (NC), or active noise reduction (ANR), is a method for reducing unwanted sound by the addition of a second sound specifically designed to cancel the first.
In the past few years, noise-canceling performance and sound quality have improved, and the prices of noise-canceling headphones have come down. Today, several competitors rival Bose for the...

Noise rejection is the ability of a circuit to isolate an undesired signal component from the desired signal component, as with common-mode rejection ratio . All signal processing devices, both analog and digital, have traits that make them susceptible to noise.
Adaptive noise cancelling techniques have found use in a wide range of situations, including the following: Eliminating ambient noise from the speech signals of a microphone situated in a noisy environment by using a second microphone situated near the noise source as the reference signal.
Impressive Noise Cancellation. Considering the $20 price tag, I was shockingly impressed with how well they canceled noise even though they don’t have noise cancellation technology.
Electronic noise is a common component of noise in signal processing . In communication systems, noise is an error or undesired random disturbance of a useful information signal in a communication channel. The noise is a summation of unwanted or disturbing energy from natural and sometimes man-made sources.
A noise-canceling microphone is a microphone that is designed to filter ambient noise. Technical details [ edit ] The development is a special case of the differential microphone topology most commonly used to achieve directionality.
