A din is a loud, unpleasant noise that goes on and on. A din is harsh, jarring, and often made up of many sounds crashing together at once.

Picture a school cafeteria at peak lunchtime, with hundreds of students talking, laughing, chairs scraping, and trays clattering. That overwhelming roar is a din. Or imagine a construction site where jackhammers pound, metal clangs, and machinery rumbles all at the same time. The combined racket creates a din that makes it hard to think or hear yourself speak.

The word often appears when someone is bothered by noise. A teacher might struggle to teach over the din of students chatting before class starts. Your parents might say they can't hear the doorbell over the din of your little brother's drum practice.

Unlike a sudden bang or crash, a din continues. It's sustained noise that fills a space and sometimes feels like it's pressing in on you from all sides. When the din finally stops, the silence feels almost startling.
