There are a few factors that make music different from noise. One of the main factors is the way the sound waves combine to create harmonious and pleasing sounds, whereas noise often lacks this harmony and can sound chaotic or unpleasant. Additionally, music typically incorporates a variety of different pitches and tones, which can combine to create melodies and harmonies that elicit emotional responses in listeners. The loudness or intensity of the sound can also play a role, as music often has a more intentional and controlled dynamic range than noise. Overall, the combination of harmony, variety, and intentional sound dynamics distinguish music from noise.
