why subs ultrasonic not infrasonic? (or normal sonic)

[Shannon]

At this time, I believe that for most people, 4 hours a day of continuous exposure would be way too much of 6G. I may end up producing it with 30 minutes of audio and 30 minutes of silence, or 60/60. It may be that that allows for a balanced effect and longer usage; that's what I'm hoping. At that point, it might be possible to use it 4 or maybe more hours a day without overdoing it. But I don't know yet; I have not gotten that far into testing variants yet.

If I cannot find a way to balance it otherwise, it looks like it will probably be 1-3 hours of use per day. From what I have seen, there is the potential for it to do really well within that range of usage time per day. More testing is, of course, needed.

I really like the idea of a "timer" in the 6G format - some kind of "tell" (physical or otherwise) that lets you know you're done for the day, or achieved the goal of the script - however it is you decide to implement it.

That may not be possible, and it may not work for everyone. But I'm looking into something like that.
