In filmmaking, ambience (also known as atmosphere, atmos, or background) consists of the sounds of a given location or space. [1] It is the opposite of "silence". Ambience is similar to presence, but is distinguished by the existence of explicit background noise in ambience recordings, as opposed to the perceived "silence" of presence recordings.
Background noise or ambient noise is any sound other than the sound being monitored (primary sound). Background noise is a form of noise pollution or interference . Background noise is an important concept in setting noise levels.
Alternatively ambient noise levels may be measured to provide a reference point for analyzing an intrusive sound to a given environment. For example, sometimes aircraft noise is studied by measuring ambient sound without presence of any overflights, and then studying the noise addition by measurement or computer simulation of overflight events.
Noise figure, the ratio of the output noise power to attributable thermal noise; Ambient noise level, the background sound pressure level at a given location; Noise power, with several related meanings; Noise spectral density, N o measured in Watt/Hertz; Noise temperature, temperature that would produce equivalent semiconductor noise
These sounds are used to suggest futuristic technology in a science fiction film, or are used in a musical fashion to create an emotional mood. [2] Each of these sound effect categories is specialized, with sound editors known as specialists in an area of sound effects (e.g. a Car cutter or Guns cutter). Foley is another method of adding sound ...
Ambient intelligence (AmI) refers to environments with electronic devices that are aware of and can recognize the presence of human beings and adapt accordingly. This concept encompasses various technologies in consumer electronics , telecommunications , and computing.
"A science fiction story is a story built around human beings, with a human problem, and a human solution, which would not have happened at all without its scientific content." [13] Basil Davenport. 1955. "Science fiction is fiction based upon some imagined development of science, or upon the extrapolation of a tendency in society." [14] Edmund ...
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 ...
