In Edgar Allan Poe's "The Fall of the House of Usher," Roderick Usher's madness intensifies primarily because he hears the sounds of Madeline below. After Madeline is entombed in the vault, Usher experiences heightened paranoia and terror, partly due to the belief that she is still alive, as well as the horrific sounds that he perceives emanating from the vault, which contribute to his descent into madness.
