Recorded Sound
1877 |
Thanks to Jen O. for this suggestion. Thomas Alva Edison stunned
witnesses by shouting "Mary Had a Little Lamb!" into the
recording funnel of his experimental phonograph. The
attached needle indented a foil-covered wax cylinder, and
then rode over the indentations to reproduce the
sound. Edison, hearing impaired from the age of 12 after a bout of scarlet fever, often referred to the phonograph as his favourite invention. |
