A ratio in decibels is ten times the logarithm to base 10 of the ratio of two power quantities. A decibel is one tenth of a bel, a seldom-used unit. The decibel is used for a wide microbar. The reference level is set at changes of some quantity. the typical threshold of perception of an average human and there are common comparisons used to illustrate different levels of sound pressure. As with other decibel figures, normally the ratio is a variety of measurements in science and engineering, most prominently in acoustics, power ratio rather than a pressure. electronics, and control theory. In electronics, the gain of amplifiers, attenuation of signals, and signal-to-noise ratios are often expressed in decibels. SENSING SURVIVAL The Sense of Hearing
