Play guide
- 1At the open Echo Tube, use the position shown by its instructions and say "hello" at an ordinary volume.
- 2Listen for the return, then try "hello there" with the same voice. Each pick the clearer result.
- 3Swap speaker and listener. Try your names next, leaving space for the echo to finish.

If it's tricky
The site is too noisy to hear a return: choose a different open exhibit rather than speak louder.
