S to N changes as much as power quality over nite, unless you live far far away from an urban or flight path
again, most don’t own or use a good SPL meter to measure the noise floor over time
how many db is your fridge, heat pump, etc ?
a lot of power conditioning gets sold and it does zip to change the drone from 405 or Jets turning ....
Always a good question for the GIK guys, how do I quiet the room ?
