-Shannon says tocalibrate it using the ocean surf,so the faintest sounds are still heard.This is 33 % for me,with the particular headphones.On my other ones as well.
but:
-in the instructions for Am,Shannon says to never go above 25 % volume on headphones with ultrasonics.
So,which is the right way ? If I lower it To 25 %, where I don't hear the lowest parts audibly,and where I hear the trickling stream very little,will it work as intended ?
Maybe it is that I can't understand what exactly ultrasonic is .I know it is only the affirmations,no masking ,but can they still he heard with a lot of noice around .. and can they work this way wig only 15% volume on headphones ..
Hi, Shannon advises against using ultrasonics with headphones, only masked should be used with headphones. And, I already answered above about volume for ultrasonic with speakers, -32db at the source is the max. This is in the instructions for programs.
Yes they can be heard with a reasonable amount of noise around. They seem to carry well even with noise around. Shannon tested ultrasonics within a concert setting and apparently each test subject showed absolute signs of influence from the subliminal tested.
