Frequensee app how to measure?


I use the ultrasonic version on my phone (iphone x), but one thing is not completely clear for me. I use an other phone (galaxy s7) to measure the volume with the frequensee app. But where do I need to hold my s7 to measure the volume? Near the speakers of the Iphone or the place where I’m going to sit when listening?

And is it true that the decibels should be around -60?


I usually hold the phone near the speaker, then I move about the room just to make sure the sound is filling the room. And yes, -60db is good, but I shoot for around -50db.

Suggestions: Easier way to calibrate the listening volume
Masked on Speakers
