Does it happen to be a macerating toilet? The one I had demonstrated to me sounds like this. In fact, the owners called it "the angry bear" because that is what it sounds like.

Thanks for sharing your idea. It is not a macerating toilet, so it can’t be that. Since several people have mentioned the possibility of it being the vent, my husband is going to check that even though he doesn’t understand why that could cause a problem. I guess he’ll find out!
