How can I turn off the sound for the facebook notifications on my iPhone?

My notifications used to not make any noise they just lit up but now they are vibrating and going off like they are a text. I would like them to go back the way they were.

open Settings/notification/facebook, and just turn off the sounds..

Put your iphone into silent mode then go to settings>facebook>push notifications> then disable all the push notifications. you could try turning vibrate off under facebook settings also

I found out how to turn them off. Go into settings, notifications, scroll down and click on the app, and then u should have the option to turn sounds off
