Sound is just a pressure wave. So, a liquid/solid doesn't compress much, so the wave zips through. The wave going through air mushes through a very compressible material. I wouldn't say the difference is 20-30ms for something 500-1000m away. For something 700m away, the sound takes two seconds in air, about 0.45 seconds in water, so you're talking about 1.5 seconds difference.

I see. So the difference is indeed detectable by plain ear, right?

Oscar is having a little joke. Hence the LOL smilie at the end of his post.:ping:

The sonar WILL hear it sooner than you will hear it on the Tower because sound travels faster in Water than in air!

An Explosion 5km away will be heard by the sonar in 3,3 secounds and you will hear it 15,1 after it goes off.

How is the hydrophone operator going to hear anything if the boat is surfaced? ;)

haha, you are right!

cheers

playing at 78% realism here but for some reason the game didnt take my settings at first, game seems to load pretty fast though i notice during about the halfway point i notice my network activity light blinking.. My internet connection is not the fastest DSL connection but working flawless so far during gameplay

No, but then again you don't have to be surfaced to see a target. Submarines have these things called periscopes.

One niggle about "realistic sound travel time" was that it was it didn't change the HYDROPHONE BEARING like it does in real life. You see a moving sound source will be heard "where it was" instead of "where it is" thus the bearing to a ship's center not only has to reflect the fact the propellers are in the back of the craft but also that the ship is no longer in the same position it was by the time the sound reaches the hydrophone. Real TDC (at least in fleet boats) accounts for this bearing delay but the hydrophone operator would not hear "lightspeed" sound.

SH4 got these effects wrong, the actual bearing and the hydrophone bearing were "lightspeed" as well as any changes in sound (say the DD RPMs up) were instantaneous to the hydrophone operator. Let's hope SH5 doesn't get this wrong as well.

I nominate you for the Most Optimistic Person in History Award. :haha:

So, we can turn off health bars. This is something we have known for a long time. But how about the mechanics? Is it still a "health point" system? Or when you turn it off does it change?

I don't remember where, but it has been said before by the devs that the mechanics remains unchanged. Although, the sinking mechanics are more complex than in previous titles.

Again, as far as I know, there's no drama.

Really? Submarines have periscopes? I'll be darned.

:rotfl2::rotfl2:

No, not at you - at me! Because of the previous periscope question, I was assuming the boat was underwater, and the soundman won't hear it any sooner than I will because I'm also underwater. I didn't even notice the "in the tower" statement!:dead:

Yes, assuming that he can hear it while surfaced, the sound will reach the hydrophones more quickly than it will reach the bridge. But will it be soon enough for him to get to a voice tube to report it to you before you hear it yourself?

I'd like to accept this nomination on behalf of the Academy.
