If you’re recently downloaded a sound-meter app onto your smartphone, or purchased a handheld sound-level meter, so that you can begin gathering data on unnecessary noise in the places you care about, then this bit of history may interest you. Here’s the quiz question: Who invented the first device for recording sound? If you guessed Thomas Alva Edison (who was famously deaf), you’re wrong. Edison didn’t (re)-invent the sound-recording device until 20 years after the first guy, a Frenchman named Edouard-Leon Scott de Martinsville, patented his invention in 1857.
Unfortunately, M. de Martinville didn’t know what to do with his invention, so he never pursued it. That didn’t stop him from being annoyed when Edison showed up in Paris 20 years later with his own sound recording device covered by American patents. But then Edison didn’t know what to do with it either—he thought he was perfecting Alexander Bell’s work. Only later did Edison decide to market his discovery as the “phonograph”—i.e., a device for recording and playing back sounds, thereby inventing the recording industry as well as the sound-level meter and a whole profession devoted to measuring noise.
Interested in history? Then you’ll definitely want to follow the Princeton researcher and MacArthur Fellow who re-discovered M. de Martinsville, Emily Thomson PhD. And if you’re reading this column you’re probably interested in urban noise and what can be done about it. Well, Dr. Thompson has written a fascinating book about urban noise and its history titled,“The Soundscape of Modernity: Architectural Acoustics and the Culture of Listening in America, 1900-1933” (MIT Press, 2002).
Dr. Thompson is definitely worth knowing about, and her work is a pleasure to read.
