2. Noise-canceling microphone - Wikipedia

   en.wikipedia.org/wiki/Noise-canceling_microphone

   The internal electronic circuitry of an active noise-canceling mic attempts to subtract noise signal from the primary microphone. The circuit may employ passive or active noise canceling techniques to filter out the noise, producing an output signal that has a lower noise floor and a higher signal-to-noise ratio.

3. Humbucker - Wikipedia

   en.wikipedia.org/wiki/Humbucker

   Guitar pickups reproduce this noise, which can be quite audible, sounding like a constant hum or buzz. This is most noticeable when using distortion, fuzz, compressors, or other effects which, by adding gain to low-level signals, reduce the signal-to-noise ratio and therefore amplify the unwanted interference relative to the signal from the ...

4. Active noise control - Wikipedia

   en.wikipedia.org/wiki/Active_noise_control

   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 ...

5. Noise generator - Wikipedia

   en.wikipedia.org/wiki/Noise_generator

   Multistate noise looks somewhat like flicker ( ) noise. The effect is process dependent, but it can be minimized. Diodes may also be selected for low multistate noise. [10] A commercial example of an avalanche diode noise generator is the Agilent 346C that covers 10 MHz to 26.5 GHz. [11]

6. Electro-Voice - Wikipedia

   en.wikipedia.org/wiki/Electro-Voice

   Noise cancelling microphones such as the Electro-Voice T45 lip microphone were instrumental to fighter and bomber airplane, tank, battleship and ground troop radio communications. EV licensed the patent to the government for free to be applied by other manufacturers to produce what was needed for the war supply.

7. Microphone - Wikipedia

   en.wikipedia.org/wiki/Microphone

   The self-noise or equivalent input noise level is the sound level that creates the same output voltage as the microphone does in the absence of sound. This represents the lowest point of the microphone's dynamic range, and is particularly important should you wish to record sounds that are quiet.
