This drives my horse past insanity.
In other more well built arena's the reaction is smaller, but he still reacts because he's learned he doesn't like it when the announcer speaks.
I can control him fine, but I shouldn't have such a serious (and embarassing) issue. I just leave the line-up, and get him moving. He settles down.
I started using the cotton ear balls on him. It helped slightly, but he can still hear a lot of frequencies from the PA echoing off the roof.
What I'm going to try, once show season starts back up in September, is:
T-Foam Ear Plugs in Accessories at Schneider Saddlery
And some lavender oil spread on me, and therefore smelled by him, to help calm his brain a little bit. And perhaps, me as well. XD
Now, the dangers to ear plugs that create an almost sound proof barrier- He won't hear hardly at all. The whole aspect is dangerous. Should someone walk up from behind, or in another blind spot, and touch him, he could very well spook or kick out just from pure instinct. It will, though, eliminate the sound of the PA.
I'm not using this as a quick fix. The PA system hurts my ears at times, and he hears tons better than I do. Who knows how he hears it. It simply hurts his ears. I need to take away that factor.
Has anyone else had this issue? If so, how have you handled it?
We've also taken him to shows, and just had him stand under the roof, and he was fine. It's when he's directly in the arena, under the speaker.
Sorry for the novel.
