Haha, I just wached that earlier today.
I like be bit near the end where they test the speed of sound.

Cute, but he went to a lot of trouble confirming what's been known since Edison made this:
Or since Joshua brought down the walls of Jericho:
BTW, not the world's largest horn, by a long shot:

Re: A video about a HORN!
Oh, I know. But still, I think it's interesting, especially, like Strange Kevin said, the test of the speed of sound.

Re: A video about a HORN!
We see examples of the speed of sound all the time. The most common one is when you count how many seconds elapse between seeing a lightning bolt and hearing the thunder to approximate the distance to the lightning hit. Each five seconds is about a mile. In our profession time aligning the PA to the backline amps is something we deal with a lot.

Cool video! They made the explanation of how horns work very easy for a layman to understand.

Re: A video about a HORN!
The video also reasonably explains what sound is - just wiggly air that wiggles your eardrums. Lots of layman think that speakers need to move lots of air when all they do is wiggle it back and forth a little bit and it's the pressure wave that carries the sound energy with the air barely moving at all.

Re: A video about a HORN!
Count the seconds from when you see it to when you hear it. Each second equals about 340 meters.Tom Smit wrote: ↑Sat Dec 01, 2018 1:30 am I agree. However, I could never really figure out the distance of the lightning bolt from me. In contrast, in the video, we are told how far away the two parties are, and we can see/hear the difference of when the horn was sounded, and when the others actually heard itI could never really figure out the distance of the lightning bolt from me.
Re: A video about a HORN!
It would have been more interesting if they would have used a full (or even wide) range driver, given the lack of harmonics removing folds in the straight horn. Or broadcasted a lower frequency.
Yes, Bill, this is what we want!
