The first sound recording was reportedly captured in Paris by Édouard-Léon Scott de Martinville in 1860, nearly two decades before Alexander Graham Bell’s first telephone call (1876) or Thomas Edison’s phonograph (1877), Scott recorded the sound on his ‘Phonautograph’. The Phonautograph was made to study sound vibrations graphically but in doing so he captured the first sound recording.
The absolutely amazing thing about this is that you can still hear these recordings. It does kinda sound like a muffled bee … but it’s still pretty amazing!!
