Ultrasonic use by Middle-Aged men

[Jones]

I think the answer you'll hear most is that the subs are effective even though you cannot actually "hear" the audio.

I'm 40 and I listen to both masked and silent.

I believe both the silent and the masked versions are effective.

Thanks for the reply.

Just a few moments ago, I tried an experiment with my 8-y/o son:

I played the first few moments of the ultrasonic version of "Absolute Self Confidence" through my computer speakers. Son said he could hear what sounded like "a cricket chirping really, really loud." While I could hear nothing at all.

And therein lies my confusion. In order for subliminals to be effective, one must be able to hear some "noise," whether intelligible or not? To date, I have stuck with the masked subliminals. However, I'd like to find something in the way of confirmation re: the ultrasonics, and their effectiveness; as that would enable me to take the earplugs out.

Thanks,
Ron
