I know, it's less clear, but there are colors, I have tested that with a random color generator. The colors are imprecise in the far periphery, but the basic colors can still be seen.

I guess my vision may indeed be abnormal as somebody else above suggested, since I don't get the blid spot in the central vision in the dark, either.

As for the sound, I think you just learn to hear the sine waves as speech - I tried to convert a part of audiobook (that I haven't listened to before) and I can understand it a little bit. I used praat with this script (it doesn't seem to like long sounds): http://www.mrc-cbu.cam.ac.uk/people/matt.davis/sine-wave-spe...
