Noise pollution is not tied to a single film, show or viral moment, but to a everyday complaint that creators recognise instantly online. Short clips of street noise, horns and crowd chatter are shared as reaction sounds and background effects for videos about city life, commuting and stress. Because the sound needs no words, it works across languages and formats, from short-form edits to longer comedy sketches. Its continued use comes from that simple recognisability: one noisy burst tells viewers they are in a loud, crowded place.
