Oh yeah, buy some type of accessory that is immune to silence. I'm not sure if the guy with the chocobo (Forgot his name) has anything like it, but I think he has Vox, which will cure it. Also have some eye drops and hankerchiefs too. Even if you don't use the hankerchiefs yet, you'll need them for the next boss. That should help the battle go by a lot easier.
And there's a glitch where if you go to the options menu and turn the battle speed up, you and the demon wall will be able to attack even faster, but he will go at the same speed. More attacks, which means you'll be able to kill it before it crushes you.
