Frequently, a wind-attenuating cover, called a "blimp" or "mic-blimp", is used to enclose the microphone. A blimp covered with sound-absorbing fuzzy fabric is usually nicknamed a windmuff or a "dead cat". In film crew jargon, the gruesome-sounding phrase dead cat on a stick is simply a boom microphone fitted with a fuzzy wind-screen.
In a noisy environment, both microphones receive noise at a similar level, but the primary mic receives the desired sounds more strongly. Thus if one signal is subtracted from the other (in the simplest sense, by connecting the microphones out of phase) much of the noise is canceled while the desired sound is retained.
Proximity effect can be viewed in two ways. In some settings, sound engineers may view it as undesirable, and so the type of microphone or microphone practice may be chosen in order to reduce the proximity effect. On the other hand, some microphone users seek to intentionally use the proximity effect, such as beat boxing singers in hip hop music.
Graphical depiction of active noise reduction. Active noise control (ANC), also known as noise cancellation (NC), or active noise reduction (ANR), is a method for reducing unwanted sound by the addition of a second sound specifically designed to cancel the first.
Noise reduction is the process of removing noise from a signal.Noise reduction techniques exist for audio and images. Noise reduction algorithms may distort the signal to some degree.
Depending on the construction of the player the sound may acoustically couple into the record player's dust cover or other mechanical parts and cause a feedback loop into the pickup cartridge. Many In-ear monitors exhibit microphonics when headphone cables transfer vibrations due to cable movement directly to the wearers ears.
This is done by having a standard passive earplug, together with a microphone/speaker pair (microphone on outside, speaker on inside; formally a pair of transducers), so sound can be transmitted without being attenuated by the earplug. When external sounds exceed an established threshold (typically 82 dBA SPL), the amplification of the ...
Materials, such as a cupped foam coated in hard plastic, will block sound due to the thick and dampening properties of the foam. [21] Active earmuffs have an electronic component and microphones that allow the user to control their access to communication while attenuating background noise. When in loud, hazardous settings, the wearer may still ...
