Multiple Choice

Intensity of sound is primarily associated with which perceptual attribute?

The intensity of sound maps to the perceptual attribute of loudness. Intensity is the physical energy per unit area carried by the sound wave, and the auditory system translates that energy into how loud a sound seems. As intensity rises, the ear-brain combination registers a louder sensation, which is exactly what we mean by loudness. Pitch, determined by frequency, tells us how high or low a sound is, not how strong it is. Color isn’t a standard term used for hearing, and timbre describes the quality or color of a sound (its tone color), shaped by harmonic content and envelope rather than its loudness.
