Cloaking Device

[strider2289]

Do the cloaking devices seen in SG1 specifically the ones used by Nirtii and the Ashrak just cloak visually or do they block sound such as movement and footsteps aswell? Considering they can all still interact physically with everything around them I would assume you could hear footsteps. Any thoughts?

I am unsure, although the cloaked ashrak in Divide & Conquer wasn't seen nor heard by anyone, so I suppose it's possible; although I don't know if this has been established in the series/movies.

Other cloaking devices which put users out of phase or shift them slightly into other dimensions (such as the ones used by puddle jumpers, arthur's mantle & the sodan) certainly do & have been proven to do so in cannon insofar as I am aware. Other forms of cloaking technology may also be out there, we just haven't encountered it/seen them in.

the cloaking tech of merlin/sodan was different than nirti and the bug dudes from show and tell in like S2 of sg1

I would like to think that akren is right; to add to it, the Nirtii one I would think actually bends the light and/or puts them somewhat out of phase. The sodan one puts them out of phase visually because in the episode where Mitchel goes out of phase he can see, but not touch, teal'c and teal'c can see him.

Nirtti's and the Ashrak's cloak were based on the science behind the Re'tuu ability.

Do you have any evidence?

[Murzin]

the guns used to see the retuu revealed nirtii.. there is no example of the retuu gun revealing a sodan/merlin cloaked person.

different techs

i think it depends on from how it is, but nirrti chould atteck while cloak so i think it whould be possible to atteck a person in cloak

bra´tac hit the ashrak whit a staff weapon

[Mclean]

I'm not sure if they do block sound but every time I've seen them used SG1 or other base personel never get alerted by footsteps or heavy breathing (after running or whatever)

[EternalAlteran]

That part is the same as with Sodan cloaks, the Zombie Sodan was able to hit people and was killed by an explosion. Also one of the Sodan fires on Mitchell during his training while cloaked. That part is the same with all cloaks (not counting higher dimension transporters). As for footsteps, that part is unknown and sound is probably block, because we never heard the Re'tuu

I don't know,but I like more the C4 think...

"cloak" shields somebody from light. Jumpers, and all cloaks we have seen just bend light and censors. Jumpers can still be hit while cloaked.

"phase generators" shift you into another demsion. You can see and hear, but can not be saw or heard. How you interact with things is unknown. Perhaps it makes a bubble around you, when something leaves the bubble is isn't out of phase.
However, Merlin's device does not make a bubble, but makes a subspace connection with every atom in the bubble so they can leave the area of effect and stay phased out.
