I see it more as a variable to tweak in a bigger system than a direct moral lever. When you layer ambient sounds you’re changing the background context that people process, so if you design that context to prime empathy or caution it’s a subtle experiment. I’d be fascinated to map out which frequencies or rhythms actually nudge a choice, but I’d also keep a tight ethical line, making sure the influence is transparent and not a hidden manipulation. The city itself is a constant lab, and I just try to listen closely before I decide what to record.
