The screech of nails down a chalkboard may come to mind, but a major international study instead points the finger at the mournful wail of someone being ill.

Academics at Britain's University of Salford used the internet to play a series of distressing noises to tens of thousands of people, who were then asked to rate the unpleasantness of each.

The sound of vomiting proved the most upsetting, edging out the shrill sound of microphone feedback in second place.
