C)Loudness

Question

Quizplus · Accepted Answer

Decibel is the unit used to express the ratio of two values of a physical quantity, in this case, sound pressure. It is a logarithmic scale that measures the intensity of sound in relation to a standard reference level. Therefore, it is the most appropriate choice for the given description. Hertz is a unit of frequency, and loudness is a subjective perception of sound intensity.
