Help researchers and have fun with this online audio experiment.

Calls of the wild gives anyone and everyone an opportunity to take part in important scientific research at home, school or even on the move on their mobile. This fun online activity takes 5-10 minutes and is a great way to get involved with real science.
Calls of the wild was first run for National Science & Engineering Week 2013. Working with researchers at the University of Surrey and the University of Salford, the study aimed to gain a deeper understanding into the emotions evoked by certain natural sounds.
The preliminary results of the Calls of the wild experiment show songs of certain birds may aid recovery after stress; the study has also shown our response to sounds is affected by meaning- the preliminary results can be collected below.
We are still collecting data so it is not too late to take part on the Calls of the wild experiment site [1].
