The decibel (dB) is a logarithmic unit used to express the ratio of two signal values - like power, sound power or pressure, voltage, intensity etc. - where one value is a reference value. (engineeringtoolbox.com)
The study of hearing is often concerned with measuring the minimum intensity of sound that can be detected by the ear. (medscape.com)
Therefore, hearing science uses a measure of sound intensity that compresses the units of measurement into a practical range. (medscape.com)
The reference level used is the lowest sound pressure commonly detected by people and is equal to 20 uPa (2 X 10 -5 N/m 2 ), thus, the intensity level in decibel sound pressure level (SPL) = 20 log10 (sound pressure/20 uPa). (medscape.com)
