I was researching a possible Active Noise Reduction solution that would not require panels and curtains everywhere but came up short.
Lots of cool stuff out there, but a relatively unchartered territory in big spaces like that.
I think those are more effective in controlled spaces, like exhaust systems. Or, were you thinking in terms of acoustical masking?
