Can you hear a torpedo underwater?

Torpedoes used by underwater submarines produce more than just an explosive sound upon detonation. After an initial firing, the sound of the outer hatch can be heard closing. The torpedo can then be heard moving through the water to the target. The length of this sound is dependant upon the distance of the target.

What sound does a torpedo make?

Borders mentioned that the whirring of the torpedoes subtly mimicked a ticking clock as the weapons rush closer to the ship. When we see the torpedoes through the water, there is also the harsh, unsettling noise of a high-pitched engine acceleration.

How do acoustic torpedoes work?

Simple acoustic torpedo. Two acoustic transducers will react upon sound and the torpedo will detect that the signal comes from one of the side. It will then issue a command to turn towards the target. When the sound is "equal" on both sides, the torpedo will follow a straight path until it reaches its target.

How do homing torpedoes work?

The torpedo is fired to cross behind the stern of the target ship, through the wake. As it does so, it uses sonar to look for changes in the water caused by the passage of the ship, such as small air bubbles. When these are detected, the torpedo turns toward the ship.
