I liked the premise a lot. I was hooked from the start and was just expecting more from the writer. A character arc that goes somewhere. A human story behind the whole thing. A parallel between Ellen's anxiety and Peter's own quirkiness or past. Surely, there must be a skeleton in his closet, some weird stuff that happened to him as a child that got him so obsessed with sound. Alas, none of that materialized. The whole story turned into one big "B-FLAT." As flat as Kansas towards the end. Or maybe it was a bit too dark and low-key for me. However, I must say the premise of the film really piqued my interest and caused me to think. I actually have get stress from my apartment and always knew there was something that was causing it. This film opened my eyes and made me very self conscious of "sound" around me. Overall, it's a good flick.

Great for tuning fork lovers. Interesting at first, but I slowly got tuned out.

Do toasters emit a resonant hum even when turned off that alters one's mood?

Anyway, the real source of background sound dissonance is vehicle, airplane & human created sounds all of which were somehow missed.
