Subjective judgment of the level or power of sound reaching the ear. The human ear cannot give an absolute value to the loudness of a single sound, but can only make comparisons between two different sounds. The precise measure of the power of a sound wave at a particular point is called its intensity.
Accurate comparisons of sound levels may be made using sound-level meters, which are calibrated in units called decibels. + prikaži više

ETYM French, from Latin volumen a roll of writing, a book, volume, from volvere, volutum, to roll. Related to Voluble.
In geometry, the space occupied by a three-dimensional solid object. A prism (such as a cube) or a cylinder has a volume equal to the area of the base multiplied by the height. For a pyramid or cone, the volume is equal to one-third of the area of the base multiplied by the perpendicular height. The volume of a sphere is equal to 4/3 x pr3, where r is the radius. Volumes of irregular solids may be calculated by the technique of integration.
