Meet the 1960s Dolby Noise Reduction Machine

Hisssss! Do you enjoy hiss-free recordings of your favorite music and podcasts? Same. In this video, Hall Wallace, Curator of our Electricity Collections, shows how the Dolby Noise Reduction Machine worked. See the real thing along with other audio inventions in our display "America's Listening," opening on October 19, 2018, at the National Museum of American History in the Ray Dolby Gateway to Culture.

Fun object, but Dolby's technology hasn't been miniaturized and embedded in everything. It reduced analog tape hiss, which is not an unwanted artifact of digital recording.
