  2. Voice activity detection - Wikipedia

    en.wikipedia.org/wiki/Voice_activity_detection

    OVER: noise interpreted as speech due to the VAD flag remaining active in passing from speech activity to noise; NDS (Noise Detected as Speech): noise interpreted as speech within a silence period. Although the method described above provides useful objective information concerning the performance of a VAD, it is only an approximate measure of ...

  5. 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 .

  6. Sound masking - Wikipedia

    en.wikipedia.org/wiki/Sound_masking

    Sound masking is the inclusion of generated sound (commonly, though inaccurately, referred to as "white noise" or "pink noise") into an environment to mask unwanted sound. It relies on auditory masking. Sound masking is not a form of active noise control (noise cancellation technique); however, it can reduce or eliminate the perception of sound ...

    HSE inspector Matthew Lea said "The Control of Noise at Work Regulations require employers to put measures in place to ensure that their employees can work safely, without putting their hearing at risk." [8] Speaking on the dangers of exposure to noise he said "Noise-induced hearing loss is a degenerative condition and the ear cannot repair ...

  8. Soundproofing - Wikipedia

    en.wikipedia.org/wiki/Soundproofing

    A pair of headphones being tested inside an anechoic chamber for soundproofing. Soundproofing is any means of impeding sound propagation.There are several methods employed including increasing the distance between the source and receiver, decoupling, using noise barriers to reflect or absorb the energy of the sound waves, using damping structures such as sound baffles for absorption, or using ...

  9. 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 ...
