[Help Thread] New to Subliminal, how to get most effect of it

[ArcticFox]

I searched Google for Decibels and went from there. Majority of stuff I found is for the laymen and is based on the chart below. Anything technical beyond the chart and I start to get confused.



I found it on this website which explains Decibels: http://www.noisemonitoringservices.com/d...explained/

IPHONE app that can measure Decibels, I currently use this: https://itunes.apple.com/gb/app/decibel-...55923?mt=8

I've used this as well and works fine https://itunes.apple.com/gb/app/decibel-...79847?mt=8

ANDROID I haven't tried this one as I don't have an android device but it looks to do the same job: https://play.google.com/store/apps/detai...d&hl=en_GB

Every single time I use an ultrasonic sub I set my iPhone with the app running at the point of listening (either my pillow or desk chair). I then play the ultrasonic track and take note of the Decibel level, and adjust the volume accordingly. I currently set mine to 70 Decibels but I'm now thinking this is too high(?) so going down to try 60 Decibels.
