"... can be understood by comparison with the optical concept of "total
internal reflection," or by the acoustic "whispering gallery"phenomenon
experienced in large circular halls."

stand near the wall on one side, you can hear someone standing in a similar
location on the other side even when they talk very quietly - hence the term
whispering gallery.
