你们知道那是什么吗？
00:25
Silence.
2
13050
1283
寂静。
00:26
The sound of silence.
3
14780
2014
那是寂静的声音。
00:29
Simon and Garfunkel wrote a song about it.
4
17448
2694
西蒙和加芬克尔二人为它写过一首歌，
（《寂静之声》）
（《寂静之声》）
00:32
But silence is a pretty
rare commodity these days,
rare commodity these days,
5
20166
3145
但现如今寂静变得尤其罕见，
00:35
and we're all paying a price for it
in terms of our health --
in terms of our health --
6
23335
3783
而我们都在为此付出的代价
——尤其是在健康上，
——尤其是在健康上，
00:39
a surprisingly big price, as it turns out.
7
27142
2904
而且是非常巨大的代价。
00:42
Luckily, there are things
we can do right now,
we can do right now,
8
30836
3773
幸运的是，我们现在还是可以做些什么，
00:46
both individually and as a society,
9
34633
2882
不管是个人还是社会，
00:49
to better protect our health
10
37539
1881
来保护我们的健康，
00:51
and give us more of the benefits
of the sounds of silence.
of the sounds of silence.
11
39444
4062
以及让我们享受到更多寂静带来的好处。
00:56
I assume that most of you know that
too much noise is bad for your hearing.
too much noise is bad for your hearing.
12
44727
4008
我想大部分人应该知道过多的噪音
对听力会有损害，
对听力会有损害，
01:00
Whenever you leave a concert or a bar
and you have that ringing in your ears,
and you have that ringing in your ears,
13
48759
3868
你在离开一个演唱会或者酒吧的时候，
如果耳中还有余音，
如果耳中还有余音，
01:04
you can be certain that you have done
some damage to your hearing,
some damage to your hearing,
14
52651
3241
那你的听力肯定已经受到损害了，
01:07
likely permanent.
15
55916
1150
而且很可能是永久性的。
01:09
And that's very important.
16
57632
1531
这很重要。
01:11
However, noise affects our health
in many different ways beyond hearing.
in many different ways beyond hearing.
17
59801
4612
不过，噪音对健康的影响远不止于听力，
01:17
They're less well-known,
18
65096
1542
这些影响不为人所知，
01:18
but they're just as dangerous
as the auditory effects.
as the auditory effects.
19
66662
3254
但却和听觉受损同样危险。
01:23
So what do we mean
when we talk about noise?
when we talk about noise?
20
71520
2421
所以，当我们在谈论噪音时，
究竟在谈论什么？
究竟在谈论什么？
01:26
Well, noise is defined as unwanted sound,
21
74287
3093
噪音是“不被欢迎的声音”，
01:29
and as such, both has
a physical component, the sound,
a physical component, the sound,
22
77404
3597
它包括物理层面，即声音本身，
01:33
and a psychological component,
23
81025
1989
以及心理层面，
01:35
the circumstances that make
the sound unwanted.
the sound unwanted.
24
83038
3202
即该声音不受欢迎的原因。
01:38
A very good example is a rock concert.
25
86264
2295
摇滚乐演唱会就是个很好的例子，
01:40
A person attending the rock concert,
being exposed to 100 decibels,
being exposed to 100 decibels,
26
88955
4355
参加摇滚演唱会的人
会被100分贝的声音环绕，
会被100分贝的声音环绕，
01:45
does not think of the music as noise.
27
93334
2153
但却不认为那是噪音。
01:48
This person likes the band, and even
paid a hundred dollars for the ticket,
paid a hundred dollars for the ticket,
28
96043
3942
他喜欢那个乐队，
甚至花了100美元买票。
甚至花了100美元买票。
01:52
so no matter how loud the music,
this person doesn't think of it as noise.
this person doesn't think of it as noise.
29
100009
3968
所以不管音乐有多大声，
他也不会认为那是噪音。
他也不会认为那是噪音。
01:56
In contrast, think of a person living
three blocks away from the concert hall.
three blocks away from the concert hall.
30
104752
4618
反过来，想想住在演唱会场馆
三个街区以外的一个人，
三个街区以外的一个人，
02:01
That person is trying to read a book,
31
109902
2203
他正想看书，
02:04
but cannot concentrate
because of the music.
because of the music.
32
112129
2942
但因为音乐声而无法集中注意力，
02:07
And although the sound pressure levels
are much lower in this situation,
are much lower in this situation,
33
115095
3714
尽管在这里，音量已经小了很多，
02:10
this person still thinks
of the music as noise,
of the music as noise,
34
118833
2816
但他仍然会认为这是噪音，
02:13
and it may trigger reactions that can,
in the long run, have health consequences.
in the long run, have health consequences.
35
121673
5843
而且还可能触发
引起长期健康问题的反应。
引起长期健康问题的反应。
02:21
So why are quiet spaces so important?
36
129405
2605
所以为什么安静的地方如此重要？
02:24
Because noise affects our health
in so many ways beyond hearing.
in so many ways beyond hearing.
37
132656
3961
因为噪音对我们的影响
远远大于听力损害。
远远大于听力损害。
02:29
However, it's becoming increasingly
difficult to find quiet spaces
difficult to find quiet spaces
38
137051
6112
但是，现在要想找到安静的地方难上加难，
02:35
in times of constantly increasing traffic,
39
143187
3637
交通更拥挤，
02:38

你的邻居还夜夜笙歌至凌晨三点，

呼！
02:52
In 2011, the World Health

that 1.6 million healthy life years

47
164463
5884
每年人们的健康生命年总损失达160万年，
03:02
due to exposure to environmental noise
48
170371
2549
仅仅因为环境噪音，
03:04
in the Western European
member states alone.

49
172944
2539
而这还只算了西欧国家。
03:09
One important effect of noise
is that it disturbs communication.
is that it disturbs communication.
50
177086
3567
噪音的一大影响是它阻碍了沟通，
03:13
You may have to raise your voice
to be understood.
to be understood.
51
181053
2797
人们需要提高音量来让别人听到，
03:15
In extreme cases, you may even
have to pause the conversation.
have to pause the conversation.
52
183874
3474
在极端情况下，你可能还要中断对话。
03:19
It's also more likely to be misunderstood
in a noisy environment.
in a noisy environment.
53
187756
3877
而在嘈杂环境中，人们也更容易被误解。
03:23
These are all likely reasons
why studies have found
why studies have found
54
191657
3337
因此，研究发现，
03:27
that children who attend
schools in noisy areas
schools in noisy areas
55
195018
3478
在嘈杂地区上学的儿童，
03:30
are more likely to lag behind their peers
in academic performance.
in academic performance.
56
198520
3932
更倾向于在学术表现上比同龄人落后。
03:35
Another very important
health effect of noise

57
203821
2491
另一个重要的噪音带来的健康影响是，
03:38
is the increased risk
for cardiovascular disease
for cardiovascular disease
58
206336
2989
它会提高人们得心血管疾病的几率，
03:41
in those who are exposed
to relevant noise levels
to relevant noise levels
59
209349
3299
尤其是那些在较高噪音水平中，
03:44
for prolonged periods of time.
60
212672
2131
生活了很长时间的人。
03:47
Noise is stress,
61
215429
1432
噪音带来压力，
03:48
especially if we have little
or no control over it.
or no control over it.
62
216885
3071
尤其是在我们无法控制噪音的情况下。
03:51
Our body excretes stress hormones
like adrenaline and cortisol
like adrenaline and cortisol
63
219980
3939
我们的身体会分泌荷尔蒙，
如肾上腺素和皮质醇，

03:55
that lead to changes
in the composition of our blood
in the composition of our blood
64
223943
2888
它们会改变我们的血液组成，
03:58
and in the structure of our blood vessels,
65
226855
2296
还会改变我们的血管架构，
04:01
which have been shown to be stiffer
after a single night of noise exposure.
after a single night of noise exposure.
66
229175
4205
比如当我们经历了一晚的噪音后，血管就会变硬。
04:06
Epidemiological studies show associations
between the noise exposure
between the noise exposure
67
234103
4227
流行病学研究发现，
04:10
and an increased risk
for high blood pressure,
for high blood pressure,
68
238354
3445
噪音会带来高血压的风险，
04:13
heart attacks and stroke,
69
241823
2021
以及心脏病发作、中风等风险，
04:15
and although the overall risk increases
are relatively small,
are relatively small,
70
243868
3607
虽然这样的风险增加度不高，
04:19
this still constitutes
a major public health problem
a major public health problem
71
247499
3390
但这仍然是影响大众健康状况的很大因素。
04:22
because noise is so ubiquitous,
72
250913
2264
因为噪音无处不在，
04:25
and so many people are exposed
to relevant noise levels.
to relevant noise levels.
73
253201
3105
太多人一直在不同程度的噪音当中。
04:29
A recent study found that US society
74
257376
3006
近期一个研究发现，
04:32
could save 3.9 billion dollars each year
75
260406
4516
美国每年可以省下39亿美元，
04:36
by lowering environmental
noise exposure by five decibels,
noise exposure by five decibels,
76
264946
3945
只要把环境噪音降低5分贝，
04:40
just by saving costs for treating
cardiovascular disease.
cardiovascular disease.
77
268915
3513
而这也是为治疗心血管疾病省下成本。
04:45
There are other diseases
like cancer, diabetes and obesity
like cancer, diabetes and obesity
78
273184
3553
还有其它疾病如癌症、糖尿病和肥胖症，
04:48
that have been linked to noise exposure,
79
276761
2331
它们都和噪音暴露有关系。
04:51
but we do not have enough evidence yet
80
279116
2167
但我们目前实际上还没有足够的证据，
04:53
to, in fact, conclude that these diseases
are caused by the noise.
are caused by the noise.
81
281307
4525
来说明这些疾病是由噪音造成的。
04:59
Yet another important effect of noise
is sleep disturbance.
is sleep disturbance.
82
287062
3491
噪音另一个重要影响是睡眠，
05:02
Sleep is a very active mechanism
that recuperates us
that recuperates us
83
290577
3038
睡眠是一个非常活跃的机制，
来为我们恢复活力，
来为我们恢复活力，
05:05
and prepares us for the next wake period.
84
293639
2413
让我们准备好迎接下一个清醒时段。
05:08
A quiet bedroom is a cornerstone
of what sleep researchers call
of what sleep researchers call
85
296555
4143
一个安静的房间是一些研究者口中的
05:12
"a good sleep hygiene."
86
300722
1704
“一个好觉”的基石。
05:14
And our auditory system
has a watchman function.
has a watchman function.
87
302968
2940
我们的听力系统有一个“看门人”的功能，
05:17
It's constantly monitoring
our environment for threats,
our environment for threats,
88
305932
3190
它持续地检测着我们所处的环境中
是否有威胁，
是否有威胁，
05:21
even while we're sleeping.
89
309146
1566
即便是在我们睡觉的时候。
05:23
So noise in the bedroom can cause a delay
in the time it takes us to fall asleep,
in the time it takes us to fall asleep,
90
311394
5314
所以房间里的噪音
会延迟我们的入睡时间，
会延迟我们的入睡时间，
05:28
it can wake us up during the night,
91
316732
2422
还会让我们在半夜醒来，
05:31
and it can prevent our blood pressure
from going down during the night.
from going down during the night.
92
319178
3715
它会阻碍我们的血压在夜晚降低。
05:35
We have the hypothesis that
if these noise-induced sleep disturbances
if these noise-induced sleep disturbances
93
323266
3389
我们有个假设，
如果这种被噪音性睡眠障碍
如果这种被噪音性睡眠障碍
05:38
continue for months and years,
94
326679
2010
持续几个月或几年，
05:40
then an increased risk for cardiovascular
disease is likely the consequence.
disease is likely the consequence.
95
328713
4597
那么心血管疾病的发病概率将会提高。
05:46
However, we are often not aware
of these noise-induced sleep disturbances,
of these noise-induced sleep disturbances,
96
334107
4039
然而，我们常常无法意识到这些
噪音性睡眠障碍的存在，
噪音性睡眠障碍的存在，
05:50
because we are unconscious
while we're sleeping.
while we're sleeping.
97
338170
2539
因为我们在睡觉时没有意识。
05:53
In the past, we've done studies
on the effects of traffic noise on sleep,
on the effects of traffic noise on sleep,
98
341137
3879
我们曾经对在交通噪音环境中
睡觉的人做过研究，
睡觉的人做过研究，
05:57
and research subjects would often
wake up in the morning and say,
wake up in the morning and say,
99
345040
3099
研究对象们经常在早晨起来后说，
06:00
"Ah, I had a wonderful night,
I fell asleep right away,
I fell asleep right away,
100
348163
2597
“啊，我昨晚睡得很好，马上睡着了，
06:02
never really woke up."
101
350784
1733
中途也没有醒。“
06:04
When we would go back
to the physiological signals
to the physiological signals
102
352541
2803
但当我们回头看各种前晚记录的
06:07
we had recorded during the night,
103
355368
1922
身体数据时，
06:09
we would often see numerous awakenings
104
357314
2309
我们常常看到大量的身体唤醒，
06:11
and a severely fragmented sleep structure.
105
359647
3046
以及严重片段化的睡眠结构。
06:14
These awakenings were too brief
for the subjects to regain consciousness
for the subjects to regain consciousness
106
362717
5513
这些唤醒太短，不至于让被研究者恢复意识，
06:20
and to remember them
during the next morning,
during the next morning,
107
368254
2891
或者在第二天早上还能记得。
06:23
but they may nevertheless
have a profound impact
have a profound impact
108
371169
3084
但它们将会带来深远的影响，
06:26
on how restful our sleep is.
109
374277
2187
决定了我们的睡眠带来的休息价值有多少。
06:30
So when is loud too loud?
110
378273
1913
所以什么时候声音才算过大？
06:32
A good sign of too loud is
once you start changing your behavior.
once you start changing your behavior.
111
380900
3858
一个很好的信号是，你开始改变你的行为。
06:37
You may have to raise your voice
to be understood,
to be understood,
112
385752
2401
比如你可能要更大声地说话以让别人理解，
06:40
or you increase the volume of your TV.
113
388177
2228
或者你开始增加电视音量，
06:42
You're avoiding outside areas,
or you're closing your window.
or you're closing your window.
114
390849
3030
你开始避开户外区域，关上窗户，
06:46
You're moving your bedroom
to the basement of the house,
to the basement of the house,
115
394356
2656
你把你的卧室移到地下室，
06:49
or you even have
sound insulation installed.
sound insulation installed.
116
397036
2532
或者你甚至装上了隔音设备。
06:51
Many people will move away
to less noisy areas,
to less noisy areas,
117
399592
3422
很多人会搬到更少噪音的地方去，
06:55
but obviously not everybody
can afford that.
can afford that.
118
403038
2486
但显然不是所有人都可以负担得起。
06:59
So what can we do right now
to improve our sound environment
to improve our sound environment
119
407508
4045
所以我们可以做些什么
来改善声音环境呢，
来改善声音环境呢，
07:03
and to better protect our health?
120
411577
2099
从而保护我们的健康呢？
07:06
Well, first of all,
if something's too loud, speak up.
if something's too loud, speak up.
121
414473
3630
第一，如果你感觉太吵，就要表达意见。
07:10
For example, many owners of movie theaters
122
418643
2669
比如，很多电影院的老板，
07:13
seem to think that only people hard
of hearing are still going to the movies.
of hearing are still going to the movies.
123
421336
4425
好像都以为只有听力不好的人才去电影院，
07:18
If you complain about the noise
and nothing happens,
and nothing happens,
124
426296
2708
如果你抱怨过它的噪音但没有效果，
07:21
demand a refund and leave.
125
429028
2086
你可以要求退款或者直接离开，
07:23
That's the language that managers
typically do understand.
typically do understand.
126
431138
3210
电影院的经理肯定会明白你传达的信息的。
07:27
Also, talk to your children
about the health effects of noise
about the health effects of noise
127
435329
3031
你还可以教导你的孩子们
关于噪音对健康的影响，
关于噪音对健康的影响，
07:30
and that listening to loud music today
will have consequences when they're older.
will have consequences when they're older.
128
438384
4501
他们现在大声地听音乐，
以后他们将为此付出代价。
以后他们将为此付出代价。
07:35
You can also move your bedroom
to the quiet side of the house,
to the quiet side of the house,
129
443461
2993
你也可以把你的卧室移到

和这次演讲十分呼应的是，
08:12
attended a noise conference

When I returned to the United States
and entered the airport,

当我回到美国，进入机场时，
08:20
a wall of sound hit me.
143
488088
2021
无数声音像墙一样向我袭来。
08:22
This tells you that
we don't realize anymore
we don't realize anymore
144
490547
2104
这告诉我们，我们不再对
08:24
the constant degree
of noise pollution we're exposed to

145
492675

噪音污染的暴露感到敏感，
08:27
and how much we could profit
from more quiet spaces.

而且也不再意识到安静的环境
可以给我们带来多大的好处。

08:32
What else can we do about noise?
147
500600
1851
我们还能做些什么？
08:34
Well, very much like a carbon footprint,
we all have a noise footprint,
we all have a noise footprint,
148
502975

正如二氧化碳足迹一样，
我们也有噪音足迹，

08:38
and there are things we can do
to make that noise footprint smaller.

而这些是我们可以缩小噪音足迹的方式。
08:42
For example, don't start mowing your lawn
at 7am on a Saturday morning.

比如，不要在周六早上七点
就开始除草，

08:48
Your neighbors will thank you.

你的邻居会感谢你的。
08:50
Or use a rake instead of a leaf blower.
152
518247
2680
或者你可以用耙子而不是吹叶机。
08:52
In general, noise reduction at the source
makes the most sense,

总的来说，从源头减少噪音是最合理的，
08:57
so whenever you're looking
to buy a new car,

所以当你在考虑买新车，

买空调，买搅拌机，
或者其它什么的时候，

09:02
make low noise a priority.
156

把低噪音作为一个首选条件。
09:04
Many manufacturers will list
the noise levels their devices generate,

157
532889

很多制造商会把
低噪音水平考虑到设备生产中，

09:08
and some even advertise with them.
158
536649
1967
有些甚至会以此作为广告亮点，
09:11
Use that information.
159
539021
1507
好好利用这样的信息。
09:14
Many people think that stronger noise
regulation and enforcement are good ideas,

160
542014

很多认为有力的噪音法规
和执行是好的方法，
和执行是好的方法，
09:18
even obvious solutions, perhaps,
161
546009
2125
甚至可能觉得这才是最明显的解决方式，
09:20
but it's not as easy as you may think,
162
548158
2052
但这不像人们想象中简单。
09:22
because many of the activities
that generate noise
that generate noise
163
550234
2839
因为许多带来噪音的活动，
09:25
also generate revenue.
164
553097
1662
同样带来收入。
09:27
Think about an airport and all
the business that is associated with it.
the business that is associated with it.
165
555274

想想机场带来的商业效应就知道了。
09:32
Our research tells politicians
at what noise level
at what noise level
166
560801
3622
我们的研究也告诉政治家们，
09:36
they can expect a certain health effect,
167
564447
2165
怎样的噪音水平会带来怎样的健康效应，
09:38
and that helps inform better noise policy.
168
566636
2574
这会帮助更有效的噪音政策出台。
09:42
Robert Koch supposedly once said,
169
570568

细菌学家罗泊特·科赫曾说，
09:44
"One day, mankind will fight noise
as relentlessly as cholera and the pest."

“总有一天，人类和噪音的斗争会像
他们和霍乱、害虫的斗争一样残酷。”

I think we're there,

我想这一天已经来到了，
09:52
and I hope that we will win this fight,

我希望我们可以赢得这场斗争，
09:54
and when we do, we can all have
a nice, quiet celebration.

而当这实现时，我们可以举行一次
美好的、安静的庆祝活动。

ABOUT THE SPEAKER
Mathias Basner - Sleep and noise researcherMathias Basner researches the effects of noise on sleep, health, neurobehavioral and cognitive functions and more.
Why you should listen
Mathias Basner, MD, PhD, MSc is an associate professor in the department of psychiatry at the University of Pennsylvania Perelman School of Medicine. His primary research interests concern the effects of sleep loss on neurobehavioral and cognitive functions, population studies on sleep time and waking activities, the effects of traffic noise on sleep and health, and astronaut behavioral health on long-duration space missions. These research areas overlap widely. Basner has published more than 80 journal articles and reviewed articles for more than 80 scientific journals. He is currently on the editorial board of the journals Sleep Health and Frontiers in Physiology.
Between 1999 and 2008, Basner conducted several large-scale laboratory and field studies on the effects of traffic noise on sleep at the German Aerospace Center. For this research, Basner was awarded the German Aerospace Center Research Award in 2007 and the Science Award of the German Academy for Aviation and Travel Medicine in 2010. Basner developed an ECG-based algorithm for the automatic identification of autonomic activations associated with cortical arousal that was used in several field studies to non-invasively assess the effects of aircraft noise on sleep. He is currently funded by the FAA to obtain current exposure-response functions describing the effects of aircraft noise on sleep for the United States. Basner has been an advisor to the World Health Organization (WHO) on the effects of traffic noise on sleep and health on a number of occasions. He performed a systematic evidence review on the effects of noise on sleep for the recently published revision of WHO's Environmental Noise Guidelines for the European Region.
Basner is currently President of the International Commission of Biological Effects of Noise (ICBEN) and member of the Impacts and Science Group of the Committee on Aviation Environmental Protection (CAEP) of the International Civil Aviation Organization (ICAO). He also represents the University of Pennsylvania in FAA's Aviation Sustainability Center (ASCENT).
