The hydrophone is located, despite the movies, in the aft portion of the fwd torpedo tube. This was the JP sonic system. It could "hear" sounds in the frequency range of the human ear approximately.

There was also supersonic sound systems. These would be what is called "sonar" and are different from the sonic hydrophone systems.

There were two supersonic systems QC/JK and QB

QC/JK projector (Ball) was located on the Port side on the underside of the submarine
QB projector (Ball) was located on the Starboard side on the underside of the submarine

Both could be extended and retracted from a control in the conning tower.

There was also a third system used to measure depth under the keel. It was called the NM transducer and was located between and just forward of the two supersonic heads.

In SH4 JP, QC/JK, and QB are all combined in one station. Not realistic but a good compromise.
