I noticed that silent subliminals don’t give peaks at the higer frequency ranges.
I’m not sure how they work.
If it’s silent but not ultrasonic, how does it work?

The terms ultrasonic and silent are usually used interchangeably. But they’re not supposed to be silent in a sense where there’s no frequency peaks. It’s supposed to be silent meaning that you don’t hear anything because the frequency is so high.

It’s marketing As far as I can tell. “Silent” are the same as the “Ultrasonic”.
Unless they’re completely silent, which means you’ve bought a recording of silence. In that case you’ve bought lipid extracts from an ophidian.
edit: just realized this is a super old post lol
I realized after I posted, but didn’t wanna publicly admit to it
