how to make an EDF jet louder?

I know it's not a good idea for flying near a neighborhood for a long time.
BUT here's the reason I'm asking.
I've flown my Phase 3 EF-16 at my high school homecoming (yes I got principal and secretary approval) and the kids really liked it (got it all painted up w/school colors and stuff). So I might fly it again for some other school event like maybe before a varsity football game er something. So I thought making it louder for the occasion would add a bit of thrill.

But is that even possible?
And no I would not unbalance the fan to make it louder.

You could somehow install a little microphone on it and have the sound effects come through the schools speakers

At some AMA events (IE: AZ Jet Rally) there is a sound level limit of 103db for EDF jets.
But at what distance, is not specified. So it's impossible to measure until it is.

The whistle from a Nerf football can be attached as if it was ordinance. Makes a nice jet-like whine.

Done it all
Glue a piece of cardboard on the fan housing so that the other end rubs the blades of the fan. Ya know like a card hitting the bicycle spokes.

Somtimes when it's real quiet I yell to the peanut gallery " Hey, did you guys see that" or "Man that was one real neat crash" .....Yelling to the peanut gallery takes the pressure off the lack of noise issue. LOL

I've tried small plastic whistles , mount one in the tail pipe and one on each wing tip ,makes a nice jet like whine .
Go the whole way with a Lander fan and 6s for a turbine like woosh !
