In 1877, for the first time, voices, music, the barking of dogs–and all sorts of other sounds could be recorded, played back, and preserved for posterity. All through the marvel of the phonograph. Surprisingly the man who created the phonograph, Thomas Alva Edison, had no theoretical background in acoustics, and only a few months of formal schooling. And ironically, he was half deaf.
