Can you imagine what the voice of a three-thousand-year-old mummy would sound like? Last week Scientific Reports published a study that describes engineering the voice of Nesyamun—an ancient Egyptian priest and scribe whose coffin’s hieroglyphs describe him as “true of voice”—by combining his 3D-printed mouth and throat with an artificial larynx and using speech synthesizing software. This week write a personal essay about the one long-ago sound you wish to hear, if you could engineer a way. Would you choose the voice of a loved one or important historical figure, the sounds of an extinct animal or bygone technology, or perhaps simply the everyday sounds of a different era?
