The clip comes from coverage of scientists recreating a mummy's voice by scanning a preserved ancient throat and vocal tract and printing a working replica. The resulting single vowel-like 'ehh' was shared widely online because it sounded both historic and oddly comic. News clips and explainers turned that one sound into a meme, with users lifting it for mummy jokes, tomb scenes and undead reactions. Its appeal lasts because it pairs a real scientific experiment with a noise anyone can imitate and drop into a short video.
