Igeros Moshe vol 6 / OC 4:60.6 says hashma'as qol is about sounding
like a melakhah was done on Shabbos. If by "trigger level" you
mean volume, he says there that if an alarm clock cannot be heard
outside the sleeper's room, or if anyone who heard it would know
from the kind of alarm that it wasn't necessarily set the night before,
it would be permissable. (Which is any alarm clock nowadays,
but that's tangential.)

So it sounds like (sorry!) RMF holds that the volume is anything
loud enough to cause someone to be chosheish you.

Tir'u baTov!
