It is customary to distinguish between loudness level and true loudness. The former is measured by varying the intensity of a reference tone until it appears to a listener to be as loud as the sound stimulus under test. The number of decibels by which the reference tone has been raised above the minimum audible threshold is said to be the loudness level of the tone under test in phon units.  3, record 1, English, - reference%20tone
