Acoustic Noise - an overview | ScienceDirect Topics

A sound wave is both the end product of the speech production mechanism and the primary source of raw material used by the listener to recover the speaker's message. Because of the central role played by sound in speech communication, it is important to have a good understanding of how sound is produced, modified, and measured.

A sound 100 times more powerful than near total silence is 20 dB. A sound 1,000 times more powerful than near total silence is 30 dB. For example, a backhoe and a compressor each producing 90 dB have a combined output of 93 dB, not 180. But 93 dB is still twice as much noise as 90 dB. In other words, sound intensity doubles every 3 dB.

Hence, when the individual cross correlations are stacked, the noise background cannot be effectively damped, leading to a high MAD (Fig. 8). If the number of sensors is fixed, even selection maximizes the spacing among the sensors and thus reduces the noise coherence. In other words, it preserves the diversity of the original recordings.
