It expresses the ratio of two values of a power or root-power quantity on a logarithmic scale. Two signals whose levels differ by one decibel have a power ratio of 10 (approximately 1.26) or root-power ratio of 10 (approximately 1.12). The unit expresses a relative change or an absolute value. In the latter case, the numeric value e…

WebTests on common receivers and transceivers show about a 1 to 5 dB per S unit change. That is, each increase in indicated signal level on the s-meter actually represents a smaller change in received power level, as compared to the theoretical 6 dB/S unit standard. WebA sound that is 10*10*10*10 or 10000 times more intense (1*10 -8 W/m 2) is assigned a sound level of 40 db. Observe that this scale is based on powers of 10. If one sound is 10 x times more intense than another sound, then it has a sound level that is 10*x more decibels than the less intense sound.
