Audience laughter is a classic broadcast sound, long associated with sitcoms, talk shows and variety programmes where a live studio audience reacts in real time. Online, short bursts like this one have become a versatile editing tool, borrowed far beyond television and dropped into memes, reaction videos, gaming clips and short-form edits. Its appeal is simple: it supplies an instant social cue that a moment was meant to be funny. Because almost everyone recognises the sound, it still works across platforms without needing any explanation or context.
