Hello friend the answer for your question is
Whispering Gallery :-
the famous whispering gallery is it Saint Paul's Cathedral is a circular shaped chamber who's was repeatedly reflect sound waves round the gallery, so that a person talking quietly at one and can be heard distinctly at the other end. This is due to multiple reflection of sound waves from the curved walls.
Echo :-
Eeco 7 sound waves reflect from a reflecting surface at a distance from the listener. due to persistence of hearing, we keep hearing the sound for 1/10 th of a second, even after the sounding source has stopped vibrating. assuming the velocity of sound wave is 340 m/s , if the sound richest the obstacles and written after 0.1 second, the total distance covered is 34 metre. No echo is heard if the reflecting obstacles is less than 17 M away from the source..
