Minecraft, developed by Mojang and fully released in 2011, uses random cave ambience to make underground areas feel unsafe even when no mobs are visible. The sounds play in dark, enclosed spaces below ground and are stored as separate numbered files in the game audio, which is why clips like Cave Sound 22 circulate individually online. Players shared them on soundboards and in memes because the noise alone recalls countless tense mining sessions, so creators now reuse it far beyond gameplay as a shortcut for horror and suspense.
