A noise is any sound. Often, it means a sound people don't like, like the noise of traffic or a barking dog.

When someone yells "What is that noise?!" you can be sure they're not happy about what they're hearing. They mean noise as anything too loud or annoying. When it comes to music, people often disagree on what's noise and what isn't. Your noise might be another person's lullaby. A car siren will wake you up, but some noises can be soothing. "White noise" is an electronically generated sound often used to help someone fall asleep.
