It's possible in real life, and also in the game. If you go to the Hydrophone station and circle the needle around the dial, you will notice the big difference between destroyers (fast wish-wish-wish) and merchants (slow and bass sound thump-thump-thump). There are many reasons in real life for that difference, the mains being: Destroyers have boilers for a turbine engine (Constant movement) and the merchants piston engines (Hence the more noticeable push of every piston with a turn of the axis) and also the size of the screws (Larger for merchants, moving slow, and small for DDs, moving faster). |
That's very interesting!
I've read in one of the tutorials that you could estimate the ship's speed only by hearing and timing the blade's cycles. How is that possible? |
If you could count the number of revolutions per minute, you could estimate the ship's speed. As the propeller blades move through the water, they make that "swish" sound. Add up the number of swishes you hear in one minute, and divide by the number of blades on the propeller, and you have your RPMs. Once you know the RPM's, you consult your handy dandy RPM to knots chart and there you go.
EDIT: That's how it was done in real life. if you'd like to try this in SH3, the tutorial is here:
