Grand Central Terminal 'Whispering Gallery'

Inside Grand Central Terminal at 89 East 42nd Street is the vaulted, tiled area near the Oyster Bar commonly called the 'Whispering Gallery,' where the concave arches produce an audible whispering phenomenon between corners. Visitors routinely demonstrate and record the effect; videos and photos of the acoustic trick circulate widely online. The terminal itself is a frequent subject of architecture and travel posts on social media.
