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. When the sound pressure of the noise wave is
Sound is captured from the microphone(s) furthest from the mouth (the noise signal(s)) and from the one closest to the mouth (the desired signal). The signals are processed to cancel the noise from the desired signal, producing improved voice sound quality. In some cases, noise can be controlled by employing active vibration control. This ...
Adaptive noise cancelling is a signal processing technique that is highly effective in suppressing additive interference or noise corrupting a received target signal at the main or primary sensor in certain common situations where the interference is known and is accessible but unavoidable and where the target signal and the interference are unrelated, that is, uncorrelated [1] [2] [3].
One of the most noteworthy features of iOS 16 is the ability to edit and unsend text messages. It’s not as clear-cut as it seems. What really happens when you unsend a text on your iPhone

Noise reduction is the process of removing noise from a signal. Noise reduction techniques exist for audio and images. Noise reduction algorithms may distort the signal to some degree. 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.
AirPods Max, like the AirPods Pro, come with Apple's Active Noise Cancellation technology for blocking outside noise, and Transparency mode for listening to sounds around users. The "Digital Crown", similar to that of the Apple Watch , allows users to play or pause audio, control volume, skip tracks, control phone calls, and activate Siri .
