How loud is your blower, if you have one? If have FPX insert.
Ok, so how can we make this scientific...well, let's try this, I have an iphone and just download'd the app called "Decibel Ultra" (uh, yes it's free). Get the room as quiet as you can, I stand about 10ft. in front of my insert and register ~50dB.
What do you get?
