Intensity is measured in hertz, and loudness is measured in decibels.

Answer 1

Loudness refers to how loud or soft a sound seems to a listener. The loudness of sound is determined, in turn, by the intensity, or amount of energy, in sound waves. The unit of intensity is the decibel (dB). As decibel levels get higher, sound waves have greater intensity and sounds are louder.

Answer 2

Answer:

Explanation:

Loudness is the measure of response of the ear to the sound. Intensity is the sound power per unit area.

Loudness is measured in decibels. Intensity is measured in Watt per meter square.

Loudness is dependent on the sensitivity of the human ears. Intensity is independent of the sensitivity of the human ears.

Loudness is a subjective quantity. Intensity is an objective quantity.
