So there's that moment in Get Out where the main character Chris is strapped to a chair and they keep playing a clip of a spoon clinking on a teacup on the TV to knock him out/send him to the Sunken Place.
After this happens a few times, Chris eventually notices that he's been nervously tearing at the armrest's upholstery and that its cotton stuffing is now exposed.
He then literally picks cotton to stuff his ears so that he doesn't hear the next spoon clink, pretends to be knocked out when Jeremy comes along to unstrap him, then gets up while Jeremy's back is turned and knocks him out.
I think the movie is amazing, I understand the irony of him picking cotton as a black person in order to save himself and all that, it's just that this is my Indiana Jones refrigerator moment. I have since tried packing cotton balls into my ears and while there is indeed some sound dampening, I don't feel it would have realistically blocked enough sound for him to not hear the spoon clink.
I found this article that links to a few sources saying cotton blocks about 7 dB, but that wouldn't help with much. http://earplugstore.typepad.com/got_ears_get_informed/2013/06/fact-or-fiction-can-cotton-balls-protect-your-ears.html
A source linked in that article also says "Cotton cannot block out high frequency sound and will provide no protection from high sound levels." http://nasdonline.org/1172/d001014/protect-your-hearing.html
A spoon clink is one of those more piercing noises so I would think it's a higher frequency and would have just passed right through.
Considering the distance he was sitting away from the TV, I imagine they also would have had the volume turned way up, or had loudspeakers piping in the audio to make sure he could hear everything.
This distracted me from otherwise good thematic irony. In the circumstances presented by the movie, is there any conceivable way that it would have worked?
