Jackson would likely be that way too. He's veryyy weird about certain sounds.

He hides and shakes when my stepdad pops/cracks his gum in his mouth (he is really loud, in Jackson's defense).

He HATES the beep from the smoke alarm if it's batteries are low. He also hates the smoke alarm in general. Our oven gets really smoky no matter what we make so whenever he hears the oven door open, he will go and hide, just assuming the smoke alarm will go off.

There's a commercial on TV where the alarm goes off and it's like a shrill loud pitched beep (I guess similar to smoke alarm beep) and he will get off the bed and hide under it if it comes on.

It's a very specific pitch that he doesn't like. Lower pitched beeps he doesn't care about. And go figure, he can be sitting right next to a leaf blower, the air pump that blows up rafts, vacuum cleaners, motorcycles, four wheelers, ambulances and not even bat an eye! But god forbid he hears a little beep.

I haven't been able to train him to accept them because once he's in the frightened state of mind, he usually doesn't want to take food anyway. So I just let him take cover and hide for a few minutes until he realizes it's over.
