Researchers from the University of Texas at Austin unveil LightSound, a handheld device that lets the visually impaired hear a solar eclipse. Put simply, it makes use of a technique called sonification, which converts data, or light intensity in this case, to sound.
When the Moon passes in front of the Sun during a solar eclipse, the sunlight begins to dim and the LightSound device outputs a change in musical tone. For added convenience, LightSound can be attached to headphones for a personal experience or to a speaker for group listening.
No products found.
The LightSound Project’s goal is to build over 750 devices before the April eclipse. For information on upcoming workshops. Through a series of workshops held January 28 and 29 by the LightSound Project and with the support of the UT Austin Department of Astronomy, the University community built 140 LightSound devices,” said the researchers.
