Answer:
The sound of the beating heart emphasizes the madness of the narrator in “The Tell-Tale Heart,” while the sound of the crying cat in “The Black Cat” does not.
Step-by-step explanation:
In the story "The Tell-Tale Heart," we learn that the narrator of the story is tormented by the sound of a beating heart. This is the heart of a man he killed, and the reader knows that the heart cannot logically be beating. Therefore, the heart is only a symbol of the man's insanity. On the other hand, the crying cat in "The Black Cat" is a real sound that the man is not imagining, and therefore, is not a consequence of his madness.
