Of course yes!
I am surprised that no one has noticed this in Movie Theaters.
In fact the sounds of rumbling thunder, underwater explosions, heavy engine/machinery also contains infrasonics. Well produced Hollywood movies certainly have this in their audio channels.
And such low frequencies do produce a nauseating effect - mainly because of its effect on lungs, muscles, eyes (yes you can see ghosts!), heart.
