उत्तर
The loudness of the sound is measured in the unit known as decibel.
Explanation:
A logarithmic unit used to express the strength or pressure of sound waves. Unlike linear scales, decibel scales reflect how the human ear hears sound, with a little increase in decibel level resulting in a huge rise in actual sound intensity. While millimetres and centimetres measure length, decibels quantify the power level of auditory impulses.
