Sound is perceived based on human perceptual interpretation, which involves how our brains process and understand the intensity of sound waves. Volume is linked to the amplitude of sound waves: higher amplitude corresponds to a louder sound, while lower amplitude signals a softer sound. This sensory perception is facilitated by the auditory system, where sound waves enter the ear, are converted into neural signals, and ultimately interpreted by the brain.

In contrast, the other choices reflect different aspects of sound but do not directly address how volume is perceived. Physical measurements, such as pressure, relate to how sound is quantified but do not encompass the subjective experience of loudness. Pitch pertains to the frequency of the sound wave, indicating how high or low a sound is, rather than its volume. Speed of transmission deals with how quickly sound travels through different media, which does not affect the human perception of loudness. Thus, the correct understanding of volume perception emphasizes the role of human interpretation rather than purely physical measurements or characteristics of sound.
