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.
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.
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.
Ambient house is a musical category founded in the late 1980s that is used to describe acid house featuring ambient music elements and atmospheres. [73] Tracks in the ambient house genre typically feature four-on-the-floor beats, synth pads , and vocal samples integrated in an atmospheric style. [ 73 ]
Ambient noise is that part of the received noise that is independent of the source, receiver and platform characteristics. Thus it excludes reverberation and towing noise for example. The background noise present in the ocean, or ambient noise, has many different sources and varies with location and frequency. [26]
Noise that has a frequency spectrum of predominantly zero power level over all frequencies except for a few narrow bands or spikes. Note: An example of black noise in a facsimile transmission system is the spectrum that might be obtained when scanning a black area in which there are a few random white spots. Thus, in the time domain, a few ...
The noise level is the level of noise. Specifically, it may refer to: Noise (electronics) Ambient noise level; Environmental noise This page was last edited on 24 ...
Noise measurement can also be part of a test procedure using white noise, or some other specialized form of test signal.In audio systems and broadcasting, specific methods are used to obtain subjectively valid results in order that different devices and signal paths may be compared regardless of the inconsistent spectral distribution and temporal properties of the noise that they generate.
