Comment on "The Tell-Tale Heart"

The following fragment belongs to "The Tell-Tale Heart" by Edgard Allan Poe. Here is my comment.

"The officers were satisfied. My MANNER had convinced them. I was singularly at ease. They sat and while I answered cheerily, they chatted of familiar things. But, ere long, I felt myself getting pale and wished them gone. My head ached, and I fancied a ringing in my ears; but still they sat, and still chatted. The ringing became more distinct : I talked more freely to get rid of the feeling: but it continued and gained definitiveness -- until, at length, I found that the noise was NOT within my ears."

I believe Poe tries to embody what a person that has commited a crime must feel at the moment of facing the law. They try to cheat people with their Manner. But the ringing... I believe the ringing must be the feeling of guilt... REMORSE. The man feels that the sound of the old man's heart is hunting him, but it is really the feeling of guilt that he can not stand, and his own heart is beating too fast for the same reason.
