Respuesta :
The loudness depends on the amplitude of the vibration. It will be louder when the amplitude is high. Suppose when we pluck a string of the sitar it starts vibrating with low amplitude and if we apply more energy by plucking more strongly, the string will vibrate with the greater amplitude and produce a loud sound.
Hope this helps,

-- The loudness of the vibration is determined by its amplitude.
-- The pitch of the vibration is determined by its frequency.
-- The amplitude and frequency of the vibration are determined by the material characteristics of the body that's vibrating, and by how much energy is used to start the vibrations.
