I honestly really love subtle little edits like this.
Since Hal wasn’t able to hear it, I tried making it a little bit more apparent; for me the sound makes it feel like were really hearing Palpatine’s inner Sith spirit screaming out. George gave Palpatine monster like groans in Episode III after he’s electrocuted to make him seem more creature like / less human.
