I was playing catch-up on new posts I'd missed since I went to sleep, and when I was just about done.. I had the tab for page 2 of my normal "search" selected, and suddenly heard a sound that sounded like it came from posting or receiving a message on Skype. But then I noticed said tab had that little speaker icon appear on it, that meant sound had come from the tab. It couldn't have actually been Skype, because I don't even have it running.

I only heard it once, so far, also.

Edit: Okay, make that twice now, and no idea what the 2nd sound was, but it was on a post page while I was fixing some character tags on a bunch of Senran Kagura pictures.

Yes, I got bored.

Yep I heard it too.

I had a bloop noise too but I figured someone higher up was doing something mischievous.

Glad I wasn't the only one.

Well I mean I didn't hear it until after reading this page. So I already knew what it was when I heard it.

Please don't do this, it's scary.

Please keep doing things like this, next make it sound like someone is knocking/opening the door to your bedroom/house.

That'll give tons of people scares :D

Or someone gasping in horror.

Oh thank fuck. Thought I was losing it, double-checking that Skype and Steam were closed and then STILL hearing the sounds.

I was about to start blessing my computer.
