The maximum distance at which sound is audible

I've tried googling "distance + sound + audible," "distance + sound + travel," and a few variations thereof (including words like "volume" and "carry"), but it occurs to me that I'm probably never going to get anything more than formulas I'm not sure how to apply. So...
Let's say there are some people hanging out by a river, and then there's some lightly forested land, and on the other side of that, a field. If the Hatfields down by the water start screaming in terror, how far away can Mr. McCoy's field be for him to just barely hear them? (Say he has average, healthy ear-parts.)

I have kind of a guess, based on living in a valley when I was in high school. You could hear someone screaming on one side of the valley from the other, just barely, but it was almost entirely open pasture. I think the valley was about half of a mile, perhaps a little wider, but I'm not sure.

Guesses? As long as it's not wildly incorrect, I figure it'll pass. Thanks!

entering Green Park

I'm rewriting a scene set in Green Park, London, present day. My characters have just left the Green Park tube station and are about to cross Piccadilly to enter the park. What do they see? What does the entrance into the park look like? Pictures looking into the park and looking up and down Piccadilly would be very useful; I tried searching Flickr but mostly found pictures from within the park.

Thank you!

horses in Scandinavia, Very Cold Ponies

The Swedish warmblood is a pretty horse, and is far closer to the appearance of, say, the Arabian or the Mustang than the Finnhorse and the Norwegian Fjord horse are. The Finnhorse, however, can totally take it up in Sápmi (Sapmi, Sameland, Saamiland, Lapland). I don't know whether the Swedish warm blood can, but it would be really awesome if it could.
