The play using 3D sound to test people's brains
Audiences going to see The Encounter at the Barbican theatre in London are wearing special headphones so that they can absorb 'immersive sounds'.
The play, set in the Amazon rainforest, uses the power of sound to transport you to the scene.
BBC reporter Chris Vallance was one of the volunteers who had the full experience. He spoke to Gareth Fry the sound designer and neuroscience writer Rita Carter who told him how and why they came up with this idea.
“The idea is to try to find out whether, when you get a group of people who are sharing a very dramatic experience like this play is, whether something is going on that is binding them together in this experience."
