Aaaah... this. If you guys notice, there are comparison videos between the 1.0 Japanese version and the regular versions, because it was in fact changed due to the issues it caused. The suicide is fake/exaggerated. The notes however, are of such a frequency that people tend to have difficulty hearing them as they get older. (Your hearing gets worse.) They can cause headaches and could even cause significant pain to a sensitive person, but they will probably not directly induce suicide in anyone.
I can hear the notes that cause this. They caused very mild headaches after listening to the music for a significant amount of time.
Pretty amusing, to me anyway, but hardly horrific.
