Three real and terrifying sounds from science
The scariest noise we tend to hear on a day-to-day basis is the sound of our smartphone telling us we've hammered it too hard and that it's about to die.
Expiring battery beeps aside, we haven't been truly creeped out by a noise since a creaky door made us jump and scatter our Pog collection over the floor, back when we were little gadgeteers.
That's why we've decided to test our mettle by rounding up some genuinely spooky real sounds. Find a dark room, plug in your headphones, and start Halloween off in style.
