Not for using the manual hydrophones.
I took the sub up to flank speed and did constant circles. You either heard the specific targets or didn't, due to the target cruising speed set below 50% of the ships max_speed, or not. Those targets traveling at half maximum speed or greater could be heard at any sub speed, and any relative bearing.
There is one "normal" area that makes it hard to hear a target when running the subs engines (to the rear of the boat), but the target is only drowned out for a small degree of bearing at the 180 degree area. If you listen closely, you'll be able to make out the rhythmic drumming of the target engines just a few degrees off the 180 degree mark.
The manual hydrophones can be effected by the subs height in the water depending on the type of hydrophone you have (usually set by the year date, or the specific sub type). The S Class "Ball" mount needs to be submerged in order to work. It sits on the deck like a large gazing ball. So does the early "rotation head" type found on the Porpoise and other early war subs. Stock and most mods have different settings for this feature found in the below file:
The "MaxSensorHeight=" changes the required height the sub needs to be in order to pick up hydrophone sounds for both the manual and AI Sonarman. In the above RFB file the maximum height is just one meter below the waterline for the S Class ball Hydrophone. The later Hydrophones/Sonar heads are mounted on the bottom of the hull, so this figure is set to zero in
their specific parameters.
The AI subs Sonarman
is certainly effected by the subs speed and direction of the sound. This is done through the Data/Cfg/Sensors.cfg file:
Changing these parameters will have the Sonarman either deaf as a post, or the only guy who can hear a pin drop!
