You hear that? It's the sound of Facebook's next feature experiment, and it sounds like it's already starting to annoy the test user group.
The social network is currently testing an alert notification that emits a ping sound when someone writes on your Timeline, sends you a message or invites you to an event.
"We are currently testing a sound with notifications," a Facebook spokesperson told Mashable. "It's only testing with a small percentage of people and it can be controlled from the Account Settings page."
The test was first spotted by a VentureBeat reporter whose profile page was among the test audience. The writer posted a video and noted he "hates" it already. We can assume many others will not be pleased to hear a constant stream of sound alerts.
Facebook is no stranger to sending new features to a select test group, but it's unknown at this point if sound notifications will actually roll out to all members in the near future.
