Question

the loudness of sound is determined by its. this depends on two factors: the sound waves amplitude and how far the waves have traveled from the source.

Explanation:

The loudness of sound is a concept in physics related to sound waves. Amplitude of a sound wave affects its loudness (higher amplitude means louder sound). Also, as sound waves travel from the source, they spread out and the intensity (related to loudness perception) decreases with distance.

Answer:

intensity
