Explanation:

loud sound depends on amplitude, intensity, frequency and energy.

as already mention high intensity sounds are perceived as loud sounds.

and the intensity of the sound is the rate at which the energy through a cross sectional area of a medium. higher intensity means higher amplitude. if we put more energy as source means we providing higher amplitude vibrations to the particles which cause the increase in intensity result is louder sound.

mass and distance
