On Board NPS 5500 Generator with Yamaha engineNoise

I'm set up out in the middle of a field for an event. Since I was bored this morning I decided to download a decibel app for my Samsung Note 9.

Only thing running is some lights and a TV without the sound on. This has a 12v fridge so thats running off the battery.

Inside the 5th wheel on the bed it tells me 51db. I also moved to the kitchen and it was the same.

I went out side and held my phone about 3 to 4ft away from the exhaust outlet at roughly at 45 degree angle. This gave me 72 db.

I paced myself off to about 30ft straight out from the door side of the rv and measured 60.5db.

I know people have asked about sound levels over the winter so here is what I measured. The accuracy of the app is unknown.
