Signal Whistle ~ 87 dB

thingiverse

This whistle boasts two key versions: Soprano at 75mm and Alto at 130mm, both delivering impressive sound. At one foot away, it reaches an astonishing 87 Decibels non-stop. Its extended body allows for exceptional acoustics, far outdoing other whistles that merely emit piercing highs found on Thingiverse designs. Those limited pitches are utterly useless for signaling since human ears respond best to moderate tones. In stark contrast, this instrument produces rich and resonant sounds. To boot, the design can be scaled down to amplify high pitches. As someone who favors mystery over shrill sounds, I opt for the low-pitched tones offered by this whistle. Besides, it can also serve as an effective tool to train dogs in obeying orders like heeling, sitting, or lying down. Right now, this masterpiece is being 3D-printed as we speak. I plan to submit it for consideration in the Make It Loud contest and desperately require your support by viewing, liking, favoriting, adding to collections, or printing a physical copy yourself. In my deepest gratitude, I extend my sincerest thanks to fellow students of technology, particularly my astute teacher, Mr Hendricks. By lending your vote, you can not only show your confidence in our youth's capabilities but also let the grown-ups know that we teens mean business.
