quite engines while out of atmosphere

Recommended Posts

do you think it will destroy the fun if the engines couldnt be heard while they activated & out of the atmosphere? in IVA mode, the engines could be heard because their sound is transfered throuth the body of the ship itself.

i would like the iva rumble noise anytime you are in space. otherwise space is boring.

but yes, a muffled vaccuum engine rumble would be nice

Space may not conduct sound, but the structure of your spacecraft does. I'm okay with the audio effects as-is; doing without would (in my opinion) be boring.

what if they linked the in-atmosphere rocket noise volume to scale with the air pressure indicator(the one under the altimeter), and at the same time always had the sound of the rumble of the engines through the ship playing? that way as you climb the noise gets quieter until in vacuum you are left with only a muffled engine rumble when doing a burn?

Well, that would be nice. They could also add a better engine noise overall, with more crackling-fire-burny sounds.

SQUAD has to have a balance between game and simulation, when SQUAD implement a feature they have to ask two questions "Is it realistic?" & "Is it Fun?". To most people, this would not be fun.

If you want this kind of realism play 'Orbiter' :)

While strictly speaking a third person view of a craft without any physical connection would be unable to hear what is going on, perhaps the kerbals simply included a microphone in the engine compartment and radio that audio stream out to the player.

Though it is true that the engines should be muffled or fully silent while operating outside an atmosphere, in practice it is nice to have that sound effect. If you bump the throttle by mistake, you know it very quickly because of how loud it is.

I fail to see how this would affect "fun". It's a relatively simple tweak that would improve immersion without sacrificing any gameplay.

'Atmospheric sound enhancement' does all of that and also includes sonic-shockwaves in atmo and muffles engines outside without muffling music and stuff. It also provides a roar-sound in the cockpit when the engine is running.

you got a link for that one?

muffling the music really bugged me when using audio-muffler, but the low rumbling bass of the engine through the ships hull really added to immersion + RCS sounds.

Yup would like to try this too.

There is a general misconception about sound in space being exhibited in this thread. You don't need to be physically connected with another spacecraft to hear that spacecraft's engines sounds. Since microphones respond to pressure, a microphone actually would pick up "sound" in the space around a burning rocket engine, especially towards the rear! But a lot of what the microphone would hear wouldn't technically be sound.

Technically, sound is defined as a wave phenomenon, carried through a second order differential relationship between pressure and particle velocity in a physical medium. Average physical transport of that medium is not allowed- the particles can move back and forth with the sound wave, but that motion must be sinusoidal and have no average velocity component. Any motion of the medium that DOES involve an average motion in one direction is NOT considered sound. Obviously, a medium in motion does not preclude itself from carrying sound; it's just that any averaged particle motion is not considered to be "sound".

So what happens with a rocket engine in space? A rocket engine exhausts a lot of high temperature gas (typically, water vapor and maybe something else too like CO2 and CO). That gas rapidly escapes in a large cone, and perhaps, even in all directions. (To know, you would probably need to look up how fast the actual gas particles are moving at the temperature they are exhausted at- it could easily be FASTER than the average exhaust velocity.)

Anyway, this expanding gas cloud creates pressure on any surface it impinges upon. This would not technically be sound because its the entire medium in transport that creates the pressure, not a wave being carried by pressure and particle velocity. However, there undoubtedly would be some TRUE engine sound being carried by this medium.

Engines would not be the only thing that would create apparent "sound" in space. I remember that during the 1998 (or was it 1999?) HST servicing mission, when the astronauts vented the shuttle's airlock out to space when they were preparing to go out and start working on the HST, the HST's solar panels were hit by a dangerously powerful blast of pressure that nearly could have damaged them. If there had been a microphone on the HST, it would have certainly picked up this pressure blast as "sound", even though *technically*, most of the pressure wave's "volume" would not have been due to sound (as it was the medium physically transporting).

Another example would be explosions in space. Contrary to popular belief, you COULD hear them if you were close enough to be hit by the wave of expanding gas. So if you had been floating in your spacesuit just outside the Apollo 13 module when its oxygen tank exploded, you would have undoubtedly heard something.

TLDR: There IS "sound" in space, though mostly it's not really sound by the technical definition of sound. If something is releasing gas, that gas rapidly expands outward creating a pressure wave that can be picked up by microphones, and may even carry some amount of true sound with it. So it would certainly ***not*** be realistic to remove all engine sound in space!!!

I like it as is. I've been using some of the engines from Interstellar that have no sound and it is way too quiet. I can deal with unrealistic things for gameplay sake.

yeah, its' ok as is. it's not a 2001 style simulator (it's an idea for someone doing their own game tho)

I see what you mean, but wouldn't the actual rapidly expanding gas (as opposed to the air it pushes in the atmosphere) completely shred any recording equipment in its path?

That was incredibly interesting to read. I learned something today !

As for the topic, Atmospheric Sound Enhancement is the mod mentioned earlier. It displays an effect when breaking Mach 1 then sound can only be heard in a cone behind the ship. There's no sound in space either, except muffled inside the ship (and in map mode).

It's a pretty cool mod that works great with FAR and Deadly Reentry.

I'd say it depends on how close you are...

your right but I think the imaginary Microphone should be IN the cockpit/command pod so you would hear what the Kerbals hear. (in the active craft)

things like vibrations in the Hull from RCS or engine thrust, landing legs touching down, collisions, parts of the ship being effected by other forces like the thrust from another craft etc.

Being able to the hear the craft in a third person view is no more unrealistic than having a third person view in the first place. I like it the way it is.

I urge you to do an apollo style mission using Atmospheric-Sound-Enhancement mod. It adds allot of atmosphere (mind the pun :P) help with immersion.
