More Definitions of Background Noise

Background Noise means noise the receiver would experience in the absence of the intruding noise, measured at the same point as the intruding noise for a period of three minutes;
Sample 1
Background Noise is any disturbing sound other than the sound signal of the audible reverse warning device at test conditions in this regulation. Its sound pressure level is measured in dB(A) and the area considered around the vehicle is regarded as a homogeneous sound field with the same sound pressure level.
Sample 1Sample 2
Background Noise means the combined noise present in a measurement system from sources other than the test aircraft, which can influence or obscure the aircraft noise levels being measured. Typical elements of background noise include (but are not limited to): ambient noise from sources around the microphone site; thermal electrical noise generated by components in the measurement system; magnetic flux noise (“tape hiss”) from analogue tape recorders; and digitization noise caused by quantization error in digital converters. Some elements of background noise, such as digitization noise, can obscure the aircraft noise signal, while others, such as ambient noise, can also contribute energy to the measured aircraft noise signal;
