In your own experience, whats the max distance you can hear a bugle in thicker timber?

Buddy and I watched a bull on an opposite hillside from a mile away this past week. Could still hear him when he disappeared into the dark timber. I think there are a lot of variables to answer this question! All depends on the topography in my opinion.
