instantly induce physical response for testing ultrasonic vs. masked and equipment

[bits]

I support this idea! Realistically, the likelihood of someone properly using this seems to be about the same as properly using the Speaker Test sub to calibrate a player.

yea exactly, even if it takes a few days for the physical response to occur or build up it will still save a lot of time if you can first test both formats for 7 days and then see which one seems to affect you more before moving on to something like ehpra or the 6 stage sets.
