New Technology to Assist Blind Individuals Experience the 2024 Total Solar Eclipse Through Hearing and Touch

On April 8, 2024, North Americans will have the opportunity to witness a magnificent celestial event: a total solar eclipse. This eclipse is expected to be even better than the last one that occurred seven years ago. At its maximum, viewers in the right place will be in the path of totality, where light from the Sun is completely blotted out except for that of the corona, for nearly four and a half minutes.

For those who are blind or visually impaired, this celestial event can still be experienced through the innovative LightSound device. Designed and developed in 2017 by Harvard astronomer Allyson Bieryla and Wanda Díaz-Merced, an astronomer who is blind, this device uses sound to allow individuals to experience the eclipse through audio cues. The sensor on the LightSound device emits high-pitch musical tones under normal light, which gradually drop as the Moon blocks the Sun’s light.

The LightSound Project is completely open source and provides downloadable DIY instructions in English, Spanish, and French on how to build your own device. The project had a goal of building over 750 devices in conjunction with other institutions in time for the April 2024 total solar eclipse. Several listening events are planned for April 8th from Colombia to Canada, providing an opportunity for people to experience the eclipse together.

Overall, this total solar eclipse presents an exciting opportunity for people across North America to witness a spectacular celestial event. Whether viewing it in person in
