Whispering-Gallery Phenomena at St. Paul's Cathedral

  title={Whispering-Gallery Phenomena at St. Paul's Cathedral},
  author={C. S. Raman and G. Sutherland},
THE very curious and interesting acoustical effects observed in the Whispering Gallery under the dome of St. Paul's Cathedral have, as is well known, been explained by the late Lord Rayleigh as due to the curvilinear propagation of sound, the waves which proceed from a source placed close to the wall of the gallery clinging to its surface and creeping tan-gentially along it. This view was developed mathematically by Lord Rayleigh (“Scientific Papers,” vol. 5, p. 617), the theoretical… CONTINUE READING
