> If you use an air horn in any context on me there is going to be trouble, I hope you're prepared for that. If you assault someone you should expect a proportional response.

Fortunately, people like you seem to be fairly rare in my experience. After hundreds of horn uses (more than 500, easily), I might be able to count the number of times that people got noticeably angry at me for honking on one hand. I'm actually struggling to think of examples, but it has happened.

Also, horn use is not assault. It causes no harm to the typical recipient as they are in a sealed box, reducing the sound pressure appreciably. That's why I only ever use the air horn on a pedestrian or cyclist if it's absolutely unavoidable. I can only think of one instance where I honked at a pedestrian off the top of my head, and that probably saved the distracted pedestrian from serious injury.

A simple "mechanical bike horn" (no idea if that's the right term, but Google image seems to find the right thing when searching for that) might be what you want for pedestrians. I've never seen an air horn that looked usable before, so thanks for that. Looks nice for cycling in traffic.

On the left side of my handlebars I have a normal bike bell, good for pedestrians and fellow cyclists. On the right I have the air horn, good for drivers who can't hear the bell and emergency situations. I'd recommend having both a normal bell and air horn.

Yeah, bell is what I meant. Are there are any air horns that are controlled with something similar to a gear shifter (the lever thingy)?

I have not seen any air horns like that. I'd prefer something like that myself as it would make honking and braking simultaneously easier.

You should consult a professional about your issues.
