@Lurius For maximum empathy from the audience, I'd start the movie with a noisy event that induces acoustic shock. The trouble with that is the audience members might actually get tinnitus and hyperacusis in real life, and then they'd want to file a lawsuit. : )
Seriously, though, if I were a millionaire, I'd fund a movie where the leading character has tinnitus and hyperacusis. Awareness is necessary.
