As you probably saw in the video, they really aren’t. There’s a fairly significant noise from the string slapping the limbs and the overall vibrations in the bow. Of course, they’re nowhere on par with most guns, but you could still easily hear one from across the street or something.
At the risk of sounding like a snob, that’s a very cheap bow she’s using and, from what I’ve read, the most important part of silencing a recurve is adjusting the brace height to fit the bow. It’s entirely possible she did that off-screen though.
There are also things like limb dampeners you can get for recurves which apparently make a big difference, though I’ve never tried them.
There are other things to consider like the type of arrow rest in use and the poundage (power) of the bow. Since the entire bow vibrates during a shot, every part of it can contribute to the amount of noise made. Ideally, I’d like to see a “bow adjustment kit” consisting of a bow square, nocking pliers, some allen wrenches and some serving which could be used to “accurize” bows like the firearm repair/gunsmith kits, but that’s probably more work code-wise than it’s worth.
I’m also still mad that compounds are weaker than a homemade reflex recurve ingame.
