The quality or state of being loud.
The sone was proposed by Stanley Smith Stevens as a unit of perceived loudness in 1936. Loudness is the subjective perception of sound pressure. According to Stevens' definition, the sone is equivalent to 40 phons, which is defined as the loudness level of a 1 kHz tone at 40 dBSPL. The number of sones to a phon was chosen so that a doubling of the number of sones sounds to the human ear like a doubling of the loudness.
A unit of apparent loudness, equal in number to the intensity in decibels of a 1,000-hertz tone judged to be as loud as the sound being measured.The prefix phon- means sound or to hear.
Units used to measure loudness are Sone (loudness N) and Phon (loudness level L). Scroll down to related links and look at "Loudness - Wikipedia" and "Sound level change and the change of the respective factor of volume and loudness"

Decibel is a measurement of loudness.

The amplitude of a sound wave refers to the magnitude or height of the wave. It represents the intensity or loudness of the sound. Amplitude is usually measured in decibels (dB) and corresponds to the strength of the signal produced by the sound wave.
Loudness of normal adult human voice is about 70 db at three feet according to http://www.businessdictionary.com/definition/decibel-dB.html
Loudness level LN is measured in phons and the Loudness N is measured in sones. Scroll down to related links and use the fine converter "Loudness level and loudness".

Loudness - band - was created in 1980.
