the.com/whispering gallery
A dome so smug about acoustics it lets strangers swap secrets across a room.
means A curved gallery or dome where a faint whisper spoken at one wall travels clearly along the curve to someone's ear at the opposite side.
from Named simply and literally in English from 'whisper' plus 'gallery' once such spaces — most famously the one under the dome of St Paul's Cathedral — became known for the curious acoustic trick: sound hugging the concave curve of the wall and carrying far better than through open air. The physics (surfaces focusing sound waves along a curved surface) was observed and admired long before anyone fully explained it, so the name describes the experience rather than the science.
