I think u also have to provide the size of the heli as well.
Take example, TRex250 appeared to be quieter than Gaui200. I once visited SkyHobbies and saw assume customer trying out Gaui200. Since I have TRex250, I can hear that the sound is higher than TRex250. This also stated by someone who saw me flying TRex250 in Bishan.... But of course TRex450 is more noisy than TRex250.

I think most noise we hear is coming from the heli's gear (except nitro heli ).
Thus if u can get some reference on the type of gear, u can roughly gauge which heli is more noisier than the other...on the same category.
