Quizplus · Accepted Answer

Loudness is a subjective perception of sound and cannot be precisely defined in terms of physical properties of sound waves. It is affected by factors such as individual hearing sensitivity and psychological factors like attention and expectation. The other options (frequency, intensity, sound level, and wavelength) can be objectively measured and defined in terms of physical properties of sound waves.
