Does passive sonar at this time rely on human ears or do they have any kind of electronic detection of sound assisting them? How big a bonus is an electronic broadband? (Obviously, technology detecting specific frequencies, i.e., narrowband, is a huge step forward.)
Anything that can be said about passive sonar vs WW2 era submarines would be helpful and interesting, please share your thoughts and wisdom.
Thanks!
