This is a part of a future development project, where the sound will be designed in such a way that the environment will be readable through sound. I am not blind or visually impaired, so I don't know what the experience feels like, but according to the little I know, blind people are far more sensitive to sound.

If you were to think of a shooter game, which is my goal, imagine that you would be able to tell what kind of environment you are in, if the walls are good for cover, or if they are only concealment, meaning that you can hide, but the bullets would still penetrate and damage your character. Binaural three dimensional audio and occlusion of sound also play an important role here. This can help with identifying if you just escaped a sniper round passing by your ears and in which direction to seek cover. Ideally, the player should be able to tell if the footsteps in the room above are coming from a light weight enemy with a rifle, or someone carrying a heavy machine gun. That is imperative to make a tactical decision on whether one should engage or not. The player should also be able to tell if his teammates nearby are carrying a rocket launcher, an assault rifle or a shotgun. All these weapons make different sounds when handled.

What design aspects should I keep in mind to make a video game that simulates real life from an audio stand point?
