I don't think German WWII Sonar had baffles in the modern sense. The baffles on a rotating T shaped sonar are on the back edge to deaden noise entering from the back and causing contacts to be picked up on reciprocal bearings (noise picked up on the back edge, leading to a target at say 45 being detected with the sonar pointing at 235). Modern sonar has a fixed bafflle behind the sonar mount, as they are more sensitive and would pick up propeller noise at any angle. I'm fairly sure the Germans didn't have fixed baffles.

You should still be able to hear the propellers at 180 ish though - can you not?
