This sound notification is very helpful sometimes when you have minimized the Facebook window or browsing any other website or using any other application in your computer. But we know every thing has a side effect in this world, this chat sound may disturb you if you have very loud volume opened on your speakers or someone may have any other problem with it. Like most other settings, Facebook lets you turn off and disable chat sound altogether.
