This question came into my mind when I answered in my "ultrasonic calibrating" thread: Why aren't the subs in infrasonic?
Lower hearing frequencies can be turned up very high without getting damaging to the ear and it's still outside the normal hearing range so it passes the conscious mind and enters the subconscious.
Or why just not put the sub into the normal hearing range without being masked? I'm pretty sure we couldn't understand it consciously even if it were 10khz because I can hear the ultrasonic and still don't understand a word. I think it is sped up way too high for that.
I hear something like a blur with some "dips" it's just too fast. I think I hear multiple frequencies at once and during the "Blur" most overlap and during the "dips" only few overlap. Its as if Shannon is reading to us something at 40x speed in 5 frequencies simultaneously. If that's true it would definitely not be understandable even in hearing range.
Is it understandable in hearing range? If yes, how is it producing 160 words per minute, I can't imagine that being understandable.
If not, why not put it in the much safer hearing range where people know when it is too loud and won't accidentally damage their ears or have it too low to work without knowing?
Or why not put it below 20hz? That is a very safe frequency for the ears and it reaches very far as it loses way less energy/volume than high frequencies through distance (e.g. speakers from the other side of the room while sleeping).
edit: with "understandable" I mean consciously understandable. Of course the subs will always be subconsciously understandable no matter the speed as long the message isn't destroyed, but afaik for a sub it is necessary not to be understandable for the conscious mind. That is why Shannon puts an ocean surf audio above the sub, so the conscious mind doesn't understand the message and block it from entering the subconscious mind.
But seeing how many words are spoken per second, wouldn't the sub still work without being masked by another sound (ocean surf, Trickling stream) and turned up to the normal volume and frequency?
