the subjective measurement of the intensity

Explanation:

Loudness means how low or loud a sound appears to a listener. Loudness is subjective in nature. It is a measure of intensity of sound- the amount of energy. This is related to air pressure and the amplitude of the sound wave. Intensity is measured in decibels (dB). With increase in every decibel, the intensity of sound increases and a louder sound is heard.
