2. Pop filter - Wikipedia

   en.wikipedia.org/wiki/Pop_filter

   A pop filter, pop shield or pop screen is a noise protection filter for microphones, typically used in a recording studio. It serves to reduce or eliminate popping sounds caused by the mechanical impact of fast-moving air on the microphone from plosives during recorded speech and singing. Pop filters can also keep saliva off the microphone ...

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. Microphone blocker - Wikipedia

   en.wikipedia.org/wiki/Microphone_blocker

   A 3.5 mm microphone blocker with just TS channel is enough to disconnect the internal microphone, but most commercial microphone blockers have TRRS connections which in theory makes them headset blockers that in smartphones also disconnect the internal speaker in media player software because they will try to connect to the headphones, while ...

Some lightweight versions may be fitted with an elastic neck strap to hold them in place while freeing the user's hands for other tas

6. 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 ...

   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. Microphone - Wikipedia

   en.wikipedia.org/wiki/Microphone

   Many noise-canceling microphones combine signals received from two diaphragms that are in opposite electrical polarity or are processed electronically. In dual diaphragm designs, the main diaphragm is mounted closest to the intended source and the second is positioned farther away from the source so that it can pick up environmental sounds to ...
