More words about Loudness help you know it better. The Loudness is the characteristic of a sound that is primarily a psychological correlate of physical strength (also amplitude). Usually, it is known as "that attribute of auditory sensation in terms of which sounds could be ordered on a scale extending from quiet to loud."Loudness, a subjective measure, is commonly confused with objective measures of sound strength like sound pressure, sound pressure level (in decibels) and sound intensity or the sound power. Filters such as A-weighting attempt to manage sound measurements to correspond to loudness as perceived by the typical human. But loudness perception is a more complex process than the A-weighting.
