It appears that the social networking giant Facebook is testing a sound to alert users whenever they receive a new notification on the site. As usual, Facebook selectively or randomly rolls out such test features for users to test and provide feedback.
According to Meredith Chin, Facebook Manager of Corporate Communications, said the notification sounds were “currently just a test,” and there is no update on if or when they would be rolled out to all users. Depending on the feedback provided by users, Facebook will then decide whether to implement and roll out the feature to all users or not.
At present, Facebook notifications are displayed below the globe icon on the top-left corner, with a small red box and a number appearing on top of it indicating the number of new notifications. You are notified when your Page or content receives a Like or comment.
Now, each of this notification might be accompanied by a sound, which is showed in the video below.
To enable this feature, or check if you’ve got the feature, go to your Account Settings and select Notifications. From there, click “View” on the top tab and uncheck the box that says “Play a sound when each new notification is received.”
If the above mentioned option isn’t available, then there is no other way of getting the sound notifications. Don’t bother installing any Facebook apps to test similar feature.
