The other consideration is whether or not the active equipment will have a blocking effect on the noise the pilots need to hear. (The cabin inter-phone chime and any emergency messages or signals.)
Yes and No. I have a fix for that already
. Don't wanna give away my ideas tho' without some compensation
. Airbus gotta figure it out.
As for the spatial and source capture issue, I have my own creative approaches but again I will leave it up to airbus.
Have a good one...
