There is a book by Octave Mirbeau called A Chinese Torture Garden. There is a scene in the book wherein a man is tied spread-eagle upon a table below a temple bell. The bell is rung incessantly until - driven mad by its tolling - the prisoner dies in madness and agony, having rent their flesh in the struggle to escape.
Whales have the same reaction to military SONAR.
