On August 21, 2017, millions of people will view a total solar eclipse as it 
passes through the United States. However, for the visually impaired, or others 
who are unable to see the eclipse with their own eyes, the Eclipse Soundscapes 
Project delivers a multisensory experience of this exciting celestial event.
The project, from NASA's Heliophysics Education Consortium, will include audio 
descriptions of the eclipse in real time, recordings of the changing 
environmental sounds during the eclipse, and an interactive "rumble map" app 
that will allow users to visualize the eclipse through touch.

PROJECT ORIGINS

The idea for Eclipse Soundscapes came from Dr. Henry "Trae" Winter, a solar 
astrophysicist at the Harvard-Smithsonian CfA with a penchant for scientific 
engagement projects. Winter noticed a deficit in accessibility while building a 
solar wall exhibits for museums. He observed that some "accessible" exhibits 
merely included the item's name in braille, while other exhibits - including 
his own - had no accessibility component at all. Winter began to brainstorm an 
astrophysics project that would use a multisensory approach to engage a larger 
percentage of the population, including the visually impaired community.
The "Great American Eclipse" of August 2017 seemed like the perfect 
opportunity.

HEAR TOTALITY

For individuals who cannot see, hearing is an ideal way to experience the 
eclipse, since soundscapes change dramatically as the Moon passes between the 
Earth and Sun. Due to the change in light, nocturnal animals stir into action, 
while diurnal animals settle. As the Sun's light re-emerges, it often triggers 
a "false dawn chorus."

Eclipse Soundscapes is working with organizations such as the National Park 
Service (NPS), Science Friday, and Brigham Young University, Idaho, to record 
these auditory fluctuations. Many of these recordings will use microphone 
arrays that simulate human hearing, creating a sensation of 3D sound for 
listeners.

Of course, these recordings will not be available until after the eclipse, but 
visually impaired individuals can enjoy the August 21 event with the Eclipse 
Soundscapes app, which will include a narration of the eclipse's progression in 
real time using specialized imagery description techniques developed by WGBH's 
National Center for Accessible Media (NCAM). Eclipse Soundscapes' app will 
geolocate the user and start the narration to align with the planetary 
movements as they occur.

TOUCH THE SUN

The Eclipse Soundscapes' app also features an interactive "rumble map," which 
uses a smartphone's touch screen and vibrational feedback to demonstrate the 
physical qualities of an eclipse. The rumble map displays photos of the eclipse 
at various stages. When users touch the image, the app reads the greyscale 
value of a pixel underneath their finger, and vibrates the phone with a 
strength relative to the brightness of the section. As users move their fingers 
around the Sun, their smartphone will vibrate more. As they move their fingers 
into the dark spaces blocked by the Moon, the vibration will diminish and 
disappear.

BEYOND AUGUST

With these tools, the Eclipse Soundscapes team hopes to provide visually 
impaired individuals with a variety of resources to explore the eclipse on 
their own - and maybe even learn something that their sighted peers could not 
through visuals alone.

Although the August 21 eclipse will only last for a few hours from beginning to 
end, the information collected through the Eclipse Soundscapes app will live on 
as an open source primary documentation of this historic event, and as a model 
for making science accessible for all. The team aims to continue their efforts 
for upcoming total solar eclipses, including one in Chile in 2019, and another 
that will visit the central United States in April 2024.
