　　I want to spend just a moment talking about the model that we've developed, which allows us to start at the top and look at the drivers of sound, analyze the soundscape and then predict the four outcomes I've just talked about. Or start at the bottom, and say what outcomes do we want, and then design a soundscape to have a desired effect. At last we've got some science we can apply. And we're in the business of designing soundscapes.

　　Just a word on music. Music is the most powerful sound there is, often inappropriately deployed. It's powerful for two reasons. You recognize it fast, and you associate it very powerfully. I'll give you two examples. (First chord of The Beatles' "A Hard Day's Night") Most of you recognize that immediately. The younger, maybe not. (Laughter) (First two notes of "Jaws" theme) And most of you associate that with something! Now, those are one-second samples of music. Music is very powerful. And unfortunately it's veneering commercial spaces, often inappropriately. I hope that's going to change over the next few years.
