The definition of background is what is behind someone or something. Taken from a definition I had lying around "Film sound is of paramount importance to the flow of a film. Higher numbers generally mean a better specification, since there is more useful information (the signal) than there is unwanted data (the noise). Its expected magnitude is signal-dependent and constitutes the dominant source of image noise except in low-light conditions. The sound of white noise we hear as humans is the sound of all the frequencies between 20 and 20,000 Hz. The pressure of these vibrations within a given frequency range stimulates sensation in the ears and Noise generated inside wireless receivers, known as internal noise, is less dependent on frequency.

Excessive background noise in a classroom can originate from outside the building (aircraft and traffic noise, lawnmowers and leaf blowing) or from within the building (heating, ventilation, air-conditioning, plumbing systems, noise from adjacent classrooms or hallways, gymnasiums or music rooms) or noise from the students themselves. Physiological Noise-anything with the body 4. Environmental Noise. Subjective quality: Background noise may be defined as background sound that is apparent in the room, stemming from many possible sources such as the heating, ventilations, and air-conditioning (HVAC) system, other equipment in the room, exterior sources such as traffic or airplane noise, or neighboring spaces. In analog and digital communications, signal-to-noise ratio, often written S/N or SNR, is a measure of signal strength relative to background noise. 20,000 tones. The LA10 and LA90, are extensively used for rating traffic noise and background noise respectively. I have done a lot of research around here, and a few people appear to have the same audio/static problems. You can talk in a normal voice and be heard clearly even in noisy environments. They may mishear and misunderstand the communication. (Can we find and add a quotation of Milton to this entry?) 2. 140 of 2006 (Regulations). The Noise filters add or remove noise, or pixels with randomly distributed color levels. Most obviously, it can simply prevent someone from hearing what’s being said. Thus, 95 dB(A) is permissible for 4 hours, 100 dB(A) for 2 hours, and so forth, up to a maximum exposure for continuous noise of 15 minutes at 115 dB(A). Definition and examples; Sound files to show the size of a decibel; Standard reference levels ("absolute" sound level) Logarithmic measures; The filters used for dB(A) and dB(C) By definition, black noise is effectively silence with a tiny bit of random noise at some frequencies and some noise above 20kHz, which is the upper limit of human hearing. It is generally considered to be representing the background or ambient level of a noise environment.
