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.
In 1957 Willard Meeker developed a working model of active noise control applied to a circumaural earmuff. This headset had an active attenuation bandwidth of approximately 50–500 Hz, with a maximum attenuation of approximately 20 dB. [3] By the late 1980s the first commercially available active noise reduction headsets became available.
Another technique uses two or more microphones and active or passive circuitry to reduce the noise. The primary microphone is closer to the desired source (like a person's mouth). A second mic receives ambient noise. In a noisy environment, both microphones receive noise at a similar level, but the primary mic receives the desired sounds more ...
Headsets with the A2DP profile can play stereo music with acceptable quality. [7] Some A2DP-equipped headsets automatically de-activate the microphone function while playing music; if these headsets are paired to a computer via Bluetooth connection, the headset may disable either the stereo or the microphone function.
Headsets are made with either a single-earpiece (mono) or a double-earpiece (mono to both ears or stereo). The microphone arm of headsets is either an external microphone type where the microphone is held in front of the user's mouth, or a voicetube type where the microphone is housed in the earpiece and speech reaches it by means of a hollow tube.
Pixel Buds Pro was the first generation to introduce Active Noise Cancellation (ANC) and transparency modes; in ANC mode, the Pixel Buds Pro will reduce background noise, while in transparency mode, the Pro will amplify external noises to facilitate conversations without removing the earbuds. [52]

The only practical ways are to physically removing all the internal microphones (there can be more than one, like a noise cancellation mic) and only plug headsets and using the headset microphone to record when needed. Modular hardware: Cameras and microphones can be physically removed from modular hardware.
