Soundhacking allows players to see others player's location. There are many types of soundhacks and all do not work the same way.
But for they work, they require at least one thing: the coordinates of the player's sound.
sXe Injected change the sound communication channel and erase the association between the player and the sound, at the same time it introduce an imperceptible alteration in the sound position to avoid any movement prediction system.
Anti-Soundhack is a server-side feature, a cheat operates in the player's computer, this means that there is no cheat that can override this protection.
