15.39 Loudness
Loudness is a subjective measure, the perceptual correlate of amplitude of sound. There
are objective measures of sound strength, such as SPL (sound pressure level in dB), but
Loudness is affected by other factors, principally frequency (the sensitivity of the human ear
changes as a function of frequency) and duration.
The perception of Loudness varies from one person to another, so it cannot be measured
with a single metric.
