The unit of quantity on which the loudness of a sound depends is:
Open in App
Solution
The correct option is D Metre
The loudness or softness of a sound is determined basically by its amplitude. The amplitude of the sound wave depends upon the force with which an object is made to vibrate. If we strike a table lightly, we hear a soft sound because we produce a sound wave of less energy (amplitude). If we hit the table hard we hear a loud sound. Loud sound can travel a larger distance as it is associated with higher energy.
