Hi, I have a presentation in eEnglish, w. We have to talk about a use of technology in a museum, t. This is my text :

Today I’m going to talk about a technological dispositiveapparatus in Tthe Museum of theNational Marine Museum of Paris that, which we visited in March when we went to the capital.

in this context, the french word "dispositif" translates in english to "device" or "machine" or "apparatus". In your case (after reading the whole piece) I decided that "apparatus" is best because it is an immersive room.
musée nationale de la marine => national marine museum

First of all, the museum's collection of the museumhas belonged to the Marine mMinistry since 1919.

Several maritime sites are attachconnected to the Marine museum like Toulon, Cherbourg, Brest or, and Lorient.

"attached" in this context would imply they are somehow physically connected

The topics are very diversified because we can seeamongst different aspects of the maritime world.

"because" implies cause and effect

In 2017, the museum closed to the public to conceive a new museography, more modern andlayout adapted to different publicaudiences.

"publics" is not used. "museography" is rare - a more common term might be "layout" or "exhibit" or "exhibition"

After six years of work, the museum reopened its doors to the public with a brand new museographyexhibition.

For this presentation, I chose one element in than immersive room called “s"Storm and sShipwrecks” which is an immersive room".

I don't understand what you mean by "one element in the room" because you go on to talk about the entire room, not just one element in it.

The dispositionenvironment of this room is composed so as to make the public feel in totally immersioned.

"disposition" in English is more like personality or mood.

It's a soundThe room includes not only sonic immersion with the waves soundsounds of waves, but also a visual immersion because of the incurved walls.

for setting up a contrast, "not only... but also" is useful. for the walls you could also say "concave" or "curved inward"

In these walls we have thethere is water movement,ing, and it’s like we are in the ocean.

the sentence is not clear - is there real water in the walls? or maybe a projection?

The marine world is represented like as dangerous, and the visitor can feel it.

Before the entry entering the room, we can already see the theme with some artworks about shipwrecks.

These artworks are like an introduction, but they are not the only ones.

Some objects are also exposed, like lifesavers, boat parts that are wrecked and shipwreck parts.

The wave represents the swell.

what does this mean?

Definitely, tThe purpose of this room is to sensitizgive the public about sense of the dangers of the sea.

"sensitize" is used only very directly for making someone sensitive to something. more frequently used is desensitized, e.g. "We are desensitized to violence in the media"

The purpose is also to sensitizeinform the visitors about a contemporary subject that is the: migrants.

For example, on one of the waves we can find a life jacket from the boat Aquarius.

ItThis was a ship establishthat sailed to help migrants in the Mediterranean sea that has failed (or wrecked).

A ship would not be "established" - I don't know what you meant here

The sea is used like a tool forby humans, but it’s also a source of great danger because people can die.

The subject of shipwreck of migrants' ships is addressed because it is really current/factual and accurate.

if you meant to translate "actuell" from french, the word is "current". but if you meant "actual" as in truthful, then you could say it is "factual and accurate" but that's a bit redundant, maybe "factually accurate"

For this reason, many objects reminiscent of shipwrecks are arranged in the room such as life rafts, rescue flares, survival rations, etc.

The immersive sidexperience of the waves it’s possible thanks to the sounds with the speakers, but also with video mapping that exposes the movement of the wave.
