RF Whistle IV

Recently I decided to try to design my own whistle from scratch as a challenge, and this is my best design so far, the IV designating this as my fourth version. I have no idea how many decibels this produces, but it makes my ears ring for a significant period of time and gives me a headache. By ear I compared the noise level of my whistle to https://www.thingiverse.com/thing:2933021 and the micro version of https://www.thingiverse.com/thing:1192426 and mine was louder to MY ears, so it's probably a very subjective result.

If you have a decibel meter and print my design, PLEASE test it and share your results!

I hope you like my unique take on a whistle!
