#2The next iteration, sound mirrors, were featured on Tom Scott.

#3Would this still work for modern military aircraft? I wonder if this + machine learning might still be useful, given radar stealth.

I think much of the usefulness is tied up into the sound arriving substantially before the plane itself.

Many of modern aircraft is supersonic so acoustic detection would be useless, even if it technically works.

True (though stealth bombers are subsonic, just). What about headings that are not straight at you though? May still have value detecting things passing by?

#7Any idea why they're all pointed in the same direction, rather than different directions, in photo 4/10?

You don't want to scan two angles at once. Direction is determined by probing different angles, not by the difference between two angles.

#10When I played Bioshock Infinite (2013) I had wondered if the Boys of Silence were conceived based on this idea.
