Decatone Blastoid

thingiverse

This submission qualifies for the "Make It Loud" challenge.\nA ten-in-one whistle combo that screams with 10 separate tone holes and channels does the trick.\nThe Quadtone Blastoid, as measured by my iPhone 5s app using the "Decibel 10th" tool, hit 103 decibels on three consecutive trials, as evidenced in the attached screenshot. \nI figured I could do better so I isolated the loudest hole from the Quadtone Blastoid and recreated it for all ten Decatone Blastoid holes.\nThe result is the shrillest thing I've ever heard although getting it to blow loudly does take a lot of air. The picture above illustrates the effect of covering some holes in order to blast louder and sustain sound for longer periods based on one's lung capacity.\nDespite reading 103 decibels maximum with my iPhone (even though I could clearly tell which ones are the loudest) it seems like the device may be maxed out registering high-amplitude sound waves. \nAdditionally, I have rounded the mouthpiece to enable use of an air compressor with this whistle if someone dare do so.
