If you have the Facebook app installed on your iPhone or iPad, then you have probably noticed that Facebook has added some new (and slightly annoying – in our opinion) sounds effects to it. For example, the app makes a chirping sound when you refresh your newsfeed, and a sound when you like a post. If you don’t need these sounds and want to turn them off, here’s how.
*Launch the Facebook app.
*Tap on More in the bottom right corner.
*Scroll down until you get to Settings, and then tap on this option, too.
*Once there, tap on Sounds and move slide the In-App Sounds toggle to off.
That’s all there is to it.
