What turns a sound into a noise?

Explanation:
Noise is what a listener perceives as unwanted or disruptive. A sound becomes noise when it intrudes on hearing, communication, or a task—when it’s loud, unpleasant, or unwanted—rather than simply being a pleasant or purposeful sound. The deciding factor is context and perception, not just frequency or whether the sound is technically a tone or an engineered signal. A pleasant musical tone remains a sound, a very high pitch isn’t automatically noise, and an engineered signal is designed for a purpose—noise arises from its unwanted, disruptive nature in a given situation.
