"Lost Echo sits amid the voiceless mountains, And feeds her grief."

Echo"How sweet the answer Echo makes To music at night, When, roused by lute or horn, she wakes, And far away, oer lawns and lakes, Goes answering light."
In audio signal processing and acoustics, an echo is a reflection of sound that arrives at the listener with a delay after the direct sound. The delay is directly proportional to the distance of the reflecting surface from the source and the listener. Typical examples are the echo produced by the bottom of a well, a building, or the walls of enclosed and empty rooms.
"Lost Echo sits amid the voiceless mountains, And feeds her grief."
"The melancholy ghosts of dead renown, Whispering faint echoes of the worlds applause."
"Let echo, too, perform her part, Prolonging every note with art; And in a low expiring strain, Play all the comfort oer again."
"I came to the place of my birth and cried: "The friends of my youth, where are they?"—and an echo answered, "Where are they?"
"Even Echo speaks not on these radiant moors."
"And more than echoes talk along the walls."
