Hi everyone. Apologies if this has been asked already, did a few searches with no success.
Essentially what I'm concerned about are the health effects of long term exposure to ultrasonic frequencies at a moderate volume. Does anyone have any insight into this, how to mitigate any potential harm or any safety issues we should be aware of?
Currently using maximum learning throughout the night using the ultrasonic track.
Thanks in advance, and looking forward to logging my progress on the forum!
