| dB |
A logarithmic measurement unit that describes a sound's relative loudness, though it can also be used to describe the relative difference between two power levels. A decibel is one tenth of a Bel. In sound, decibels generally measure a scale from 0 (the threshold of hearing) to 120-140 dB (the threshold of pain). A 3dB difference equates to a doubling of power. A 10dB difference is required to double the subjective volume. ...

| dB |
This is the ratio of two signal levels where the relationship is governed by the equation: dB = 20Log10(v1/v2) dBu means that the ratio is measured relative to 0.775V RMS. dBm means that the ratio is a measure of power. 0 dBm equals 1 milliwatt, or 0.775V across a 600 Ohm impedance. dBV means that the ratio is a measure of voltage. 0 dBV equals 1 volt. dB SPL means that the ratio is a measure of Sound Pressure Level. 0 dB SPL equals 0.0002 dynes/ square centimeter, or 20 micro-Pascals.
