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 .
A microphone, colloquially called a mic (/ m aɪ k /), [1] or mike, [a] is a transducer that converts sound into an electrical signal. Microphones are used in many applications such as telephones , hearing aids , public address systems for concert halls and public events, motion picture production, live and recorded audio engineering , sound ...

In telephony, sidetone is the effect of sound picked up by the telephone's transmitter (mouthpiece) and instantly introduced at a low electronic signal level into the receiver (earpiece) of the same handset, a form of electrical feedback through the telephone hybrid. [1]
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.
The mid mic usually a cardioid mic, the sides using a figure of 8 mic, and the rear using another cardioid mic. This is usually used for recording ambiance sounds and not live music. [1] [2] From these three tracks, five channels can be extracted: Center= Mid/Mid Mic; Left=Mid+Side; Right=Mid+Invert(Side) Surround Left=Rear+Side
Musical tones produced by the human voice and all acoustical musical instruments incorporate noises in varying degrees. Most consonants in human speech (e.g., the sounds of f, v, s, z, both voiced and unvoiced th, Scottish and German ch) are characterised by distinctive noises, and even vowels are not entirely noise free.
An electret film is applied to the back plate of the microphone capsule and the diaphragm is made of an uncharged material, which may be mechanically more suitable for the transducer design being realized. Front electret This design features no back plate, and the capacitor is formed by the diaphragm and the inside surface of the capsule.
