Answer - Loudness of Sound is Measured in Units of decibels.
The frequency content, duration, and sound pressure level (SPL) of a sound all affect how loud something is perceived to be. We conclude that the loudness of sounds is determined by the strength of sound waves. Decibels (dB) are units used to measure loudness.
The unit of measurement for noise is the decibel (dB). the proportion of something's sound pressure to its reference pressure. Sone is a measure representing the perceived loudness of a tone at 1000 Hz that is 40 dB above the threshold, with 1 sone being the loudest possible. Phon is a unit of subjective loudness. The loudness of sounds is calculated using the intensity of sound waves. The power of a sound in Watts per square metre of the sound's coverage is how intense the sound is.

Loudness of Sound is Measured in Units of decibels. The loudness of sound depends on the sensitivity of the ear and the intensity of sound.
