Onan diesel Generator installed at its permanent location!

Today, my FIL and myself moved the generator into its spot. It is behind the house, very close to the electrical meter and the panel inside. It is located next to the deck, which shields most of the noise.

I measured noise with a sound level meter.

Here are the pictures of the Generator installed at its permanent location.
Noise Levels:

10 ft in front of the generator -- 73 dB.
Across the deck, near house -- 63 dB.
Inside the house -- can be barely heard, with effort

The piece of plywood that is behind the genset, goes in front of it when the generator is to be run. It reduces noise by whopping 5 dB.
