If this helps, if you have a Basic Diaphram for an air horn"hence you can reuse old diaphrams(with X, Fe(frequency resonance)) you can look at the length x diameter x flare rate, to make the appropriate Horn loading for best efficiency.

Found on Page 5, Tables 4, 6, 10 will be the most useful info for your application.
While this is specific to Speaker design, Sound is universal regardless of diaphram drive type used.

In my case I have been using some thick vinyl sheeting to make my horn diaphrams. It is not perfect and I have blown a couple of them up but overall it works very well and can be tuned for pitch and operating pressure. In fact I actually made a shorter one that I take to sporting events that is just lung powered and even that one is really loud.

I have also experimented with metal, plastic, and other types of diaphrams. The ideal materal to use would be a metal diaphram but it takes a lot more effort to get it sealed properly and it is a lot less forgiving to work with. I actually blew a metal diaphram out once too, and it actually shot out the back of the horn. That was pretty much the point when I decided to stick with something a little more forgiving and potentially less dangerious.

What's the obsession with horns ?
I guess I use mine maybe once or twice a YEAR.

IMHO, they're mostly used to create noise pollution, and could just as well be removed from cars.
It'd long be gone, if it weren't mandatory to have a horn ...

but that once or twice a year you do need one you want it to be loud I had a car with no horn once and the couple times I need it it was very frustrating!

I'm usually too busy driving to remember i have a horn until later.

Here's how they did it back in the day:


That's an organ pipe in the exhaust system (right behind the acetylene generator for the lights)

I've been busy with the holidays, but I will get back to this project. The tech geek in me keeps renewing my interest in the project. I had seen the Leslie Typhon videos.

Reviving an old thread... I did upgrade the horn on my motorcycle. I can say that a horn on a bike is very necessary. This is because motorcycles apparently have cloaking devices that make them invisible to other drivers. I went from a stock single low tone horn to a high and low horn module. The difference is amazing! I used a relay to get power directly from the battery.

Went from this... (click for video)
