"Listening radius" is actually a good name for it, thanks. We need new terminology for spatial-harmonic composition! In this case, the locations and harmonic relationships were chosen with this specific radius in mind, so if you increase the radius, there might be some dissonance/clashing. But now that you've put the idea in my head, I also want to try it! I might go for a little settings screen with volume and radius then.

Someone correct me if I'm wrong, but I'd think you'd call that (the not at all overloaded term) "attenuation" or more complete: "distance attenuation". Maybe it helps for further browsing :)
It seems like Wikipedia ( https://en.wikipedia.org/wiki/Attenuation_(disambiguation) ) has it under "Acoustic attenuation" but very physics-focused, not so much about the musicology, psychology or how it is used everywhere in audio.
It's related, but you'll notice that most of the audio sources actually trigger an audible starting note when entering the radius. If anything, I'd rather make it clear that we're pretty far from anything physically accurate in that regard.
