Sound Measurement Techniques

The decibel is not an absolute unit of measurement, and the dB scale (for sound pressure levels) uses the threshold of human hearing as the reference level, defined as 0 dB. Because of the logarithmic nature of the dB scale, each time we multiply the actual sound pressure level in micro-Pascals by a factor of 10, we add 20 to the dB sound pressure level.
