Ok, I have sent 2.03 to Bill.

Here is the 2.03 addition to the readme:

Enjoy! :rock: :arrgh!:

Cheers,

Two questions Sirs.
First, I understand the install/uninstall option is no longer there?
Second, did you lower the sounds of the Biologics?
Seems they have the same loudness as in the stock game.

The biologics remain at the same sound level, but now they might show up more clearly on the Sphere and Hull arrays, since they are more sensitive now.

The single-click install/uninstall option is gone, however you can still load and unload the mod very simply by restoring your stock Database and Doctrine folders (just overright the Database and Doctrine folders you use when the mod is installed). To restore, the Mod, just unzip it again to your DW directory.

People reported install problems using the .bat files and it seems the complexity of the mechanism was preventing some players from using the newest version of the mod.

Those bats were only my temporary solution for easy install/uninstall, I hoped someone could write better ones or write simple installer.
I liked the bats because they worked so simple and here was even no need to remember at which mode game is currently, just click the option you need and you got it, I even wanted to improve them further. Hm but you guys were exiting the game before doing that ?? :-?
Well Hanu pointed to an universal mod enabler here and maybe it would be more reliable, I'll check it ! :)

P.S. Looks good, should work :) Tomorrow I'll try to redo 2.03 for Generic Mod Enabler and we'll try.

The bios show like a candle in the night now. :) Seems not realistic.

Well, the whales and shrimp are set at 75 PSL, which is about as loud as a Han running fairly fast, only with no NB signature.

We'll probably reduce the PSL for these in the next version.

The singing whale is a VERY loud event, on good sonars hearable form THOUSANDS miles :-). We have data about how loud a whale sings, it almost could kill a man if it was close to it :-). But of course at first whale sing is probably not a very broadband event (although I feel it would show up on BB), and more importantly - whales don't sing all the time :-P
So the sound of whales should rather reflect their normal activity, which is much quieter I believe :-). Shrimp is quite noisy thing too (I don't remember if we had data on that), even single animal can be heard on sonar quite far, but again maybe not that loud. We'll take a look at this. Submariner's and sonarman's opinion is welcomed how far could a shrimp be heard on sphere (BB) sonar ?

I guess that depends on "how good it is." :lol: :rotfl:

The main thing to take into affect is of course the SSP. Give me a few moments to research and jog my memory...;)

Take into consideration that it would be close to seeing a noisy trawler or supertanker though. With this new computer, I don't have the dB comparisons you provided.

A few equations to work up...

FOMpassive SL + DI - NL - DT

This is just an example since I don't have the dB of biologics. Something else to consider is we don't know the exact species of whale or shrimp as this will tell the dB value produced.


The big point is that the environment pays a major role in the ranges observed. A Victor III in the Norwegian Sea (relatively quiet sea and deep) at 12 knots may be detected at several miles. The same submarine in the Med (relatively shallow and very noisy) may be detected at a 1000 yards. At flank speed (27 knots), the Victor III may be detected at 20 miles direct path, 25-40 miles bottom bounce, and possibly to 3 or more CZ's (convergence zones) at 30-33 miles, 60-66 miles and 90-99 miles in the Norwegian Sea, by ship based sensors and sonobouys, and for literally thousands of miles by SOSUS.

Source Level (SL) expressed in decibels (dB). Sound pressure level of individual noise sources of the target, i.e. propellors, drive shafts, reduction gears, steam turbines, electrical generators, reactor coolant pumps, diesel engines, main propulsion motors, other pumps and motors, speed related components (hull resonance's occurring at different speeds). ASW tacticians and operators will use the most detectable steady state noise sources for a given target as their primary detection, classification, and tracking frequencies.


Ambient Noise (AN) expressed in decibels at a given frequency(dB)(which includes sea state, rain, biologics, distant shipping noise, underwater geologic disturbances, etc.) i.e., anything not target related.

Recognition Differential (RD) expressed in dB. The sensitivity of the equipment and operator proficiency (i.e. ability to detect and classify a target unalerted). Tends to be a subjective number.

Directivity Index (DI) in dB. The improved sensitivity of directional sonar systems, where the receivers can be focused on a given sector.

Propagation Loss (PL) in dB at a given freq.. Sound energy is attenuated by spreading losses, absorption (sound energy converted to heat energy), reflection, refraction, etc. Prop loss varies directly with frequency.

Self Noise (SN) in dB. Primarily flow noise over the sensor array, but can also include system noise, artifacts (caused by electrical interference within the equipment-- a design limitation, also affects RD).

Target Strength (TS) in dB. The "sonar cross section" of a target. Amount of sound energy reflected from a target.

Signal Excess (SE) in dB. How much signal is left after accounting for all the variables mentioned above.

These variables are what make up the passive and active sonar equations. The passive sonar equation is as follows:

SE = SL - PL - AN - RD + DI

Propagation loss is usually calculated and displayed on a graph, to which we apply a Figure Of merit (FOM), calculated from a version of the passive equation:

FOM = SL - AN - RD + DI

Using this graph we can determine the expected detection range for a given frequency, including the usability of various transmission paths... direct path, bottom bounce, convergence zones.

Finally...some difinitive numbers.

I would defer to the airdales on this one, it makes a much bigger difference to them.

As for ASROC's, the right way to make them less "sniper" is to add some randomness to their accuracy in delivery. They're ballistic missiles after all, and I think the only guidance they have is inertial, or maybe even just timers...

I just re-noticed that you were able to change the 65-76 to only be allowed to be assigned to targets classified as Surface.

Can you change the Maverick to be allowed to be assigned to a target classed sub? This would allow the quick engagement of surfaced submarines detected visually, which revert back to sub as soon as they are changed to surface. As long as your fix for the homing is working, I don't think this would cause any problems.

That would be a great thing. I dont want Uber Missiles, but just the ability to hit everything on the surface (be it surfaced subs or surface vessels) with the Maverick without using workarounds. Which btw. dont come that handy in emergency situations, like when a sub suddenly surfaces 2 nm in front of you.

With Maverick doctrine fix (included in 2.03 mod) and Sub type target allowed for Mav (not included in 2.03 yet) this would work exactly this way. You could launch Mavs at sub targets anytime but missiles would guide only against subs on the surface (or at least part of the sail visible, the exact triggering depth could be still tuned).

Well, now that we've got the airdales on board, we should look at the random circle/snake direction as well... perhaps do the even/odd depth--right/left direction torpedo doctrine? :) ;)
