Question

The loudness or softness of a sound is determined basically by ________.

• A. frequency
• B. pitch
• C. amplitude
• D. phase

Answer 1

The correct option is C amplitude

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.
