Decibel definition

Decibel means a dimensionless measure of Sound Level or Sound Pressure Level, denoted as dB;

Decibel means a unit of measurement of sound pressure level that is equal to 20 times the logarithm to the base 10 of the ratio of the pressure of a sound, divided by the reference pressure of 20 micropascals; (“décibel”)

Decibel means a unit of sound level on a logarithmic scale measured relative to the threshold of audible sound by the human ear, in compliance with American national standards institute standard S 1.1-1960.

More Definitions of Decibel

Decibel or “dB” means a unit that denotes the ratio between two quantities which are proportional to power; the number of decibels corresponding to the ratio of two amounts of power is ten (10) times the logarithm to the base of ten (10) of this ratio.

Decibel means a unit for measuring the amplitude of sound, equal to 20 times the logarithm to the base 10 of the ratio of the pressure of the sound measured to the reference pressure, which is 20 micropascals.

Decibel means the ratio between levels of sound pressure expressed as 20 times the logarithm to the base of 10 of the said ratio;

Decibel means the practical unit of measurement for sound pressure level; the number of decibels of a measured sound is equal to 20 times the logarithm to the base 10 of the ratio of the sound pressure of the measured sound to the sound pressure of a standard sound (20 micropascals); abbreviated “dB”.

Decibel means one-tenth of “Bel” which is the fundamental division of a logarithmic scale used to express the ratio of two specified or implied quantities, the number of “Bels” denoting such a ratio being the logarithm to the base of 10 of this ratio. The noise level (or the sound pressure level) corresponds to a reference pressure of 20 x 10 Newton per square meter or 0.0002 dynes per square centimeter which is the threshold of hearing, that is, the lowest sound pressure level necessary to produce the sensation of hearing in average healthy listeners. The decibel in abbreviated form is dB.

Decibel means the unit measure of sound level, abbreviated as dB.

Decibel means a unit for expressing the relative intensity of sounds on a scale from zero for the average least perceptible sound to approximately 130 for the average pain level;
