3D-printed LightSound device converts light brightness into sounds for visually impaired to experience solar eclipses.

A Harvard team has developed a 3D-printed device called the LightSound, which turns the changing brightness of light into a variety of sounds, allowing visually impaired people to experience a solar eclipse. The device uses a process called sonification, converting data into sound. The LightSound is about the size of a cell phone and can be used to make astronomy more accessible to those with physical impairments.
