Q concerning cSpeedNoise

Hm, when we take following example:

- noise level defined in object database: 65
- cNoise of a typical nuclear engine: 21 (ignoring cBaseNoise)

So, the main question is for me if 65 and 21 really refer to the same unit.

If 21 means the additional noise at maximum power, then it is somewhat similar to the Harpoon 3 sonar model (http://www.harpoonhq.com/harpoon3/sonar_model.html). The Harpoon 3 sonar model seems to be inferior to DW's sonar model...it just assumes that the emitted sound increases one 1 dB / knot for all units, which is rather quite simple.

But on the other hand that the total sound level at maximum speed (ignoring cavitating effects, there is an additional modifier for that) is just 1/3 more than a sub, hovering at 0 zero...seems also strange (?)
