I was in a parade with a band and fire sirens behind us, a cop directly in front of us, and we also went past four streets filled with millions (felt like it) of screaming little kids. My horse was asleep the entire ride, haha!! He did not care about the noise at all.
It just takes time and practice and to get them bombproof.
I would take him near the roads where there are cars often and jsut work him around on ground and in the saddle near, but not too close, to the road. I rode by the road once with cars wizzing by and he was sligthly nervous the frst time, but once he knew that they weren't going to jump ou t and murder him randomly then he was okay with it.
When we showed a car alarm went off and my horse was the only one who didn't spook.
Over the years he has gone through everything and we have worked him hard and long until he was fine with a object.
I'm not sure exactly how you would go about this, because we have ahd him for ten years and I only remember three - the years that I ahve been riding for.
But it takes lots of time and patience to work with everything.
