The Royal Society's Laughter Project
|Help scientists understand how we perceive sounds.|
|Listen to recording of laughter; decide if they are real or not.|
Just listen to a few laughs and tell us whether they are real or posed.
The results will help scientists from University College London to understand the way we perceive and react to different sounds. The experiment should take about 10 minutes.
