I found online, I cannot find the original link but there are numerous out there, an "air horn" made from a 35 mm film canister. Instead of making my own film canister I cheated.
I used the film canister by smily77 and modified it for the new use that it will have.
The note, as posted here, is 502 Hz or a B at roughly 84 dB.
If I figure out how to make a configurable set I will replace the current files with one that will take a note wanted and scale the models.
The horn has been printed, and while I perceive a difference in the volume, the sound meter that I am using, a phone app so meh, does not register anything more than 84 dB.

I really hate being on film so ignore the stupidity.
Please note. Use this responsibly. This is meant to be used at sporting events or concerts. Someplace where there is already a lot of noise. Soccer / Futbol is the best event with American Football being next.

After running through another balloon, I decided to play with different materials to form the diaphragm. Using regular notebook paper seems to work very well!
