1968 Sub vs Sub tips?

Great info Bandit, thanks for that. Have you got the Mod 0 or Mod 3 to show up as separate weapons in inventory or did you replace the standard Mod 2?

And yes, I've had good luck with the stock 120 dB pre-enable speed and a modded 130 dB enable speed, but that's just my guess at the difference in noise.

Your 10db gain in sound intensity of the torpedo in going from inactive to active speed is not a bad estimate in my opinion. My assumption would be that the sound intensity would be proportional to the power output of the torpedoe's engine. Since the fluid drag on the torpedo varies approximately as the square of the speed and the power is equal to the force exerted by the torpedo times its speed, then the power would vary as the cube of the speed. I would then write the sound increase in db as 30*log(v2/v1).
