I have been thinking for a minute on how the 3T22/2T22 have roughly the same decibel rating as the STH-10. I came to the point where I thought it seems that rotor spacing of the 3T22/2T22 models has a lot to do with it. And it seems to work. My reasons behind this are that the sound output of both the rotors on the 3/2T22 is horizontal, but there is also vertical spacing between the rotors. Putting that into contrast, it means that one of the rotor's outputs are not going to affect the other rotor's output. Now, considering that one rotor was just above the other, or even connected, the decibel rating would increase because the outputs of both rows would "interfear" with each-other. This would cause a sound-pressure difference in that one medium of air they're traveling through. Think of two batteries; each attached to its own seperate wire. One wire's current would not affect the other. But now put both batteries in one wire: guess what happens. So, the closer the rotor rows are to each-other, the smaller that medium of air that they're going to affect will be; and therefore, more pressure.
Now my month-old question is answered. It only took me less than a minute as I only thought of the question today!

He is a dumbass...
No wonder he had to pay just to get into class.
All the problems in the world today...
Republicans had to relate to it in some way.
