Question

differentiate between intensity and loudness in three.

Answer 1

• Loudness is related to the amplitude of sound waves - Intensity is the rate at which power is transferred across a given area.
• Loudness is actually the perception of sound by the listener -  Intensity is a property of the sound source.
• The loudness of sound is measured in decibels (dB) - Intensity has units watts per square metre (W/m2).

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.
