Wanda Díaz-Merced, a blind astronomer, and Allyson Bieryla, a Harvard astronomer, have developed the LightSound device that allows blind individuals to experience the stages of a total solar eclipse through sound. The device converts changes in luminosity into audible tones, with high tones representing sunlight, mid-range notes signaling the Moon’s coverage of the Sun, and low sounds marking the arrival of darkness. The device was first used during the 2017 total solar eclipse in the United States.
The LightSound device is being distributed by different organizations across Mexico, Canada, and the United States at events to provide an accessible experience for blind individuals. It can also be utilized in museums and university workshops to offer a unique sensory experience of celestial phenomena.
One of its significant advantages is its energy efficiency and environmental friendliness. The device has already been tested in Peru and received positive feedback for its noise reduction capabilities.
Furthermore, the LightSound device can connect to headphones or speakers to project auditory experiences to groups during an eclipse. This innovative initiative aims to make astronomical events more inclusive and accessible to individuals with visual impairments.
Overall, this pioneering technology expands enjoyment and understanding of celestial phenomena beyond just those with sight.
