I might upgrade my car horn to this. Shoutout to Portal from Facebook for their support on this video. Learn more and get yours at: portal 2OG9U7j
Watch the What's Inside video here:
Here is a behind the scenes video from the day:
High Speed camera courtesy of They rent high speed cameras at killer prices. Hit them up.
ELI20 version: I answered why you want a large outlet area but not necessarily why it curves like that. Anytime you have a sudden change in cross-sectional area in the horn you will get waves reflecting back at the source. You don't want that because that is wasted energy that could have moved forward. Even if it goes from a small cross-section to a larger, if you do it suddenly you get those wasted waves. So you want the horn to basically be asymptotic at the exit so you never have a jump in discontinuity when it exits to the wide open air. So a directors cone isn't as good as the curved shapes I showed because it still has the sudden change when it dumps into the open air.

Summary: I made a huge horn and broke glass with it and explored why horns are shaped the way they are.

They are soft-

I make videos like this once a month all year long while supplies last:

The wind will blow the sound away, so the waves will not go straight. I am wrong? What happened with the tiny pieces of the glass?
