Why is the word 'volume' associated with sound level,although in Physics,it is not an attribute of sound?

The term 'volume' with reference to sound is indicative of loudness as experienced by a listner which is a combined effect of more than one parameter.For example,frequency,amplitude etc.Volume is also the product of three dimentions-length,breadth and height.Hence,the term,'volume' is best indicative of the loudness of sound a product of several parameters.
