  2. Echo suppression and cancellation - Wikipedia

    en.wikipedia.org/wiki/Echo_suppression_and...

    Echo suppression and echo cancellation are methods used in telephony to improve voice quality by preventing echo from being created or removing it after it is already present. In addition to improving subjective audio quality, echo suppression increases the capacity achieved through silence suppression by preventing echo from traveling across a ...

  3. 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 .

  4. Echo removal - Wikipedia

    en.wikipedia.org/wiki/Echo_removal

    Echo removal is the process of removing echo and reverberation artifacts from audio signals. The reverberation is typically modeled as the convolution of a (sometimes time-varying) impulse response with a hypothetical clean input signal, where both the clean input signal (which is to be recovered) and the impulse response are unknown.

  5. Audio feedback - Wikipedia

    en.wikipedia.org/wiki/Audio_feedback

    To maximize gain before feedback, the amount of sound energy that is fed back to the microphones must be reduced as much as is practical.As sound pressure falls off with 1/r with respect to the distance r in free space, or up to a distance known as reverberation distance in closed spaces (and the energy density with 1/r²), it is important to keep the microphones at a large enough distance ...

  6. Adaptive feedback cancellation - Wikipedia

    en.wikipedia.org/wiki/Adaptive_feedback_cancellation

    Echo cancellation is a form of adaptive feedback cancellation used in telephones and teleconferencing devices. Much like adaptive feedback cancellation in hearing aids, echo cancellation uses an adaptive filter to cancel echo reverberations from a microphone. [5]

  7. Delay (audio effect) - Wikipedia

    en.wikipedia.org/wiki/Delay_(audio_effect)

    Delay is an audio signal processing technique that records an input signal to a storage medium and then plays it back after a period of time. When the delayed playback is mixed with the live audio, it creates an echo-like effect, whereby the original audio is heard followed by the delayed audio. The delayed signal may be played back multiple ...

  8. Measurement microphone calibration - Wikipedia

    en.wikipedia.org/wiki/Measurement_microphone...

    A microphone’s sensitivity varies with frequency (as well as with other factors such as environmental conditions) and is therefore normally recorded as several sensitivity values, each for a specific frequency band (see frequency spectrum). A microphone’s sensitivity can also depend on the nature of the sound field it is exposed to.

  9. Noise-cancelling headphones - Wikipedia

    en.wikipedia.org/wiki/Noise-cancelling_headphones

    Without power, some models do not function as regular headphones. Any battery and additional electronics may increase the size and weight of the headphones compared to regular headphones. The noise-cancelling circuitry may reduce audio quality and add high-frequency hiss, although reducing the noise may result in higher perceived audio quality ...
