Avoid using the psychoacoustical terms loudness perception and volume.
This subjective sound-sensation is not clearly measurable without ambiguity.
The term "loudness" or "volume" is a problem because it belongs to psycho-
acoustics and this personal feeling is not correct definable.
Loudness as a psychological correlate of physical strength (amplitude) is also
affected by parameters other than sound pressure, including frequency,
bandwidth, spectral composition, information content, time structure, and the
duration of exposure of the sound signal. The same sound will not create the
same loudness perception by all individuals (people).
