Hear the World is working on measuring the sounds of the world by creating a global sound map. The map currently shows sound levels in Chicago and New York (in the United States). The site shows you the decibel level at different sites around the city and shows you where you might want to wear earplugs! The site has Union Square in NYC measured at 74 decibels (dB) and “The Bean” at Millennium Park in Chicago at 73 dB. A wonderful visualization of the sounds around us!
