The document describes two tests conducted with unknowing participants. The first test, called "Party People", involved playing music for 11 testees and observing if they enjoyed it after 90 minutes. The second test, called "Noise-Tunnel", involved guiding participants through three rooms, each with different loud sounds, to observe their reactions and experience passing through the noise tunnel. The end of the document simply states "The End".
