So, I have been going nuts wondering what Nolan can and can't hear. All of the regular hearing loss simulators on the web are for high-frequency loss, and can' t simulate a cookie-bite or reverse-slope loss. THEN someone on the listen-up listserv told me about this program which can simulate any type or level of hearing loss. They have generic settings, and you can also manually move the bars to get the loss by frequency!
I downloaded it and have been having some "fun" playing with it this morning.
It definitely gives me a better idea of what Nolan can and can't hear (he is actually missing quite a lot).
