(traffic noise) we stand on street corners, shouting over noise like this, and pretending that it doesnt exist. well, this habit of suppressing sound has meant that our relationship with sound has become largely unconscious.there are four major ways sound is affecting you all the time, and id like to raise them in your consciousness today. first is physiological. (loud alarm clocks) sorry about that. ive just given you a shot of cortisol, your fight/flight hormone. sounds are affecting your hormone secretions all the time, but also your breathing, your heart rate - which i just also did - and 精品文档2016 全新精品资料-全新公文范文 -全程指导写作 独家原创 2 / 8your brainwaves.its not just unpleasant sounds like that that do it. this is surf. (ocean waves) it has the frequency of roughly 12 cycles per minute. most people find that very soothing, and, interestingly, 12 cycles per minute is roughly the frequency of the breathing of a sleeping human. there is a deep resonance with being at rest. we also associate it with being stress-free and on holiday.the second way in which sound affects you is psychological. music is the most powerful form of sound that we know that affects our emotional state. (albinonis adagio) this is guaranteed to make most of you feel pretty sad if i leave it on. music is not the only kind of sound, however, which affects your emotions.natural sound can do that too. birdsong, for example, is a sound which most people find reassuring. (birds chirping) there is a reason for that. over hundreds of thousands of years weve learned that when the birds are singing, things are safe. its when they stop you need to be worried.精品文档2016 全新精品资料-全新公文范文 -全程指导写作 独家原创 3 / 8the third way in which sound affects you is cognitively. you cant understand two people talking at once (if youre listening to this version of) (me youre on the wrong track.) or in this case one person talking twice. try and listen to the other one. (you have to choose which me youre going to listen to.)we have a very small amount of bandwidth for processing auditory input, which is why noise like this - (office noise) - is extremely damaging for productivity. if you have to work in an open-plan office like this, your productivity is greatly reduced. and whatever number youre thinking of, it probably isnt as bad as this. (ominous music) you are one third as productive in open-plan offices as in quiet rooms. and i have a tip for you. if you have to work in spaces like that, carry headphones with you, with a soothing sound like birdsong. put them on and your productivity goes back up to triple what it would be.the fourth way in which sound affects us is behaviorally. with all that other stuff going on, 精品文档2016 全新精品资料-全新公文范文 -全程指导写作 独家原创 4 / 8it would be amazing if our behavior didnt change. (techno music inside a car) so, ask yourself: is this person ever going to drive at a steady 28 miles per hour? i dont think so. at the simplest, you move away from unpleasant sound and towards pleasant sounds. so if i were to play this - (jackhammer) - for more than a few seconds, youd feel uncomfortable; for more than a few minutes, youd be leaving the room in droves. for people who cant get away from noise like that, its extremely damaging for their health.and thats not the only thing that bad sound damages. most retail sound is inappropriate and accidental, and even hostile, and it has a dramatic effect on sales. for those of you who are retailers, you may want to look away before i show this slide. they are losing up to 30 percent of their business with people leaving shops faster, or just turning around on the door. we all have done it, leaving the area because the sound in there is so dreadful.i want to spend just a moment talking about the model that weve developed, which allows us to 精品文档2016 全新精品资料-全新公文范文 -全程指导写作 独家原创 5 / 8start at the top and look at the drivers of sound, analyze the soundscape and then predict the four outcomes ive 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 weve got some science we can apply. and were in the business of designing soundscapes.just a word on music. music is the most powerful sound there is, often inappropriately deployed. its powerful for two reasons. you recognize it fast, and you associate it very powerf
