What is the "whispering gallery" in the U.S. Capitol?
The half-dome shape of National Statuary Hall produces an acoustical effect whereby, in some spots, a speaker many yards away may be heard more clearly than one closer at hand. The modern-day echoes occur in different locations from those in the 19th century, when the floor and ceiling of the hall were different.
