Which of the following are the measurable characteristics of sound?

Explanation:
Sound has quantifiable physical properties. Frequency measures how often the pressure wave repeats each second, and this is what determines the perceived pitch. Intensity describes the energy of the wave, relating to how loud it sounds. Duration is simply how long the sound lasts. Together, these three capture the basic measurable aspects of a sound signal. Pitch, while closely linked to frequency, is a perceptual attribute rather than a direct physical measurement. Timbre—or quality—depends on the harmonic content and envelope of the sound and isn’t captured by a single measurement; it’s described by multiple spectral and temporal characteristics.
