你們知道那是什麼聲音嗎？
00:25
Silence.

寂靜。
00:26
The sound of silence.

2014
寂靜的聲音。
00:29
Simon and Garfunkel wrote a song about it.

賽門與葛芬柯
以它為主題寫了一首歌。

00:32
But silence is a pretty
rare commodity these days,
rare commodity these days,
5
20166
3145
但現今，寂靜非常稀有，
00:35
and we're all paying a price for it
in terms of our health --
in terms of our health --
6
23335
3783
我們也都要為此付出
健康方面的代價，
健康方面的代價，
00:39
a surprisingly big price, as it turns out.
7
27142

結果發現，這個代價大得驚人。
00:42
Luckily, there are things
we can do right now,
we can do right now,

幸運的是，有一些行動
是我們現在就可以採取的，
是我們現在就可以採取的，
00:46
both individually and as a society,
9
34633
2882
包括個人的行動和社會的行動，
00:49
to better protect our health
10
37539
1881
來把我們的健康保護得更好，
00:51
and give us more of the benefits
of the sounds of silence.
of the sounds of silence.
11

4062
讓我們從寂靜的聲音
得到更多的益處。
得到更多的益處。
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
我猜想大部分人都知道，
太多噪音對你的聽覺有害。
太多噪音對你的聽覺有害。
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
若你離開音樂會或是酒吧時，
耳朵會聽見鳴聲，
耳朵會聽見鳴聲，
01:04
you can be certain that you have done
some damage to your hearing,
some damage to your hearing,
14
52651
3241
那就可以確定你的聽力已經受損，
01:07
likely permanent.
15
55916
1150
且可能是永久性的。
01:09
And that's very important.
16
57632
1531
那是非常重要的。
01:11
However, noise affects our health
in many different ways beyond hearing.
in many different ways beyond hearing.
17
59801
4612
然而，除了聽力之外，噪音還會以
許多其他的方式影響我們的健康。
許多其他的方式影響我們的健康。
01:17
They're less well-known,
18
65096
1542
這些方式比較少人知道，
01:18
but they're just as dangerous
as the auditory effects.
as the auditory effects.
19
66662
3254
但卻和聽力受影響一樣危險。
01:23
So what do we mean
when we talk about noise?
when we talk about noise?
20
71520
2421
所以，我們說的「噪音」
是什麼意思？
是什麼意思？
01:26
Well, noise is defined as unwanted sound,
21
74287
3093
噪音的定義，是不想聽到的聲音，
01:29
and as such, both has
a physical component, the sound,
a physical component, the sound,
22
77404
3597
就這定義來說，
它有實體的成分，即聲音，
它有實體的成分，即聲音，
01:33
and a psychological component,
23
81025
1989
也有心理的成分，
01:35
the circumstances that make
the sound unwanted.
the sound unwanted.
24
83038
3202
即讓造成聲音
「不想被聽到」的情境。
「不想被聽到」的情境。
01:38
A very good example is a rock concert.
25
86264
2295
一個非常好的例子
就是搖滾演唱會。
就是搖滾演唱會。
01:40
A person attending the rock concert,
being exposed to 100 decibels,
being exposed to 100 decibels,
26
88955
4355
一個人去聽搖滾演唱會，
暴露在一百分貝的音量下，
暴露在一百分貝的音量下，
01:45
does not think of the music as noise.
27
93334
2153
他卻不認為這音樂是噪音。
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
這個人喜歡這個樂團，
甚至花了一百美金買票，
甚至花了一百美金買票，
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
所以不論音樂有多大聲，
這個人都不會將之視為噪音。
這個人都不會將之視為噪音。
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
相對的，想想看住家離
音樂會場只有三個街區的人。
音樂會場只有三個街區的人。
02:01
That person is trying to read a book,
31
109902
2203
這個人想要看本書，
02:04
but cannot concentrate
because of the music.
because of the music.
32
112129
2942
但卻因為音樂而無法專心。
02:07
And although the sound pressure levels
are much lower in this situation,
are much lower in this situation,
33
115095
3714
雖然在這個情況中，
聲音壓力的程度低很多，
聲音壓力的程度低很多，
02:10
this person still thinks
of the music as noise,
of the music as noise,
34
118833
2816
這個人仍然會認為這音樂是噪音，
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
且從長期來看，它造成的反應
可能會有健康方面的後果。
02:21
So why are quiet spaces so important?
36
129405
2605
所以，為什麼安靜的
空間如此重要？
空間如此重要？
02:24
Because noise affects our health
in so many ways beyond hearing.
in so many ways beyond hearing.
37
132656
3961
因為噪音對我們健康的影響
絕對不只是聽力方面而已。
絕對不只是聽力方面而已。
02:29
However, it's becoming increasingly
difficult to find quiet spaces

03:23
These are all likely reasons
why studies have found

03:38
is the increased risk

03:41
in those who are exposed

59
209349

如果暴露在高強度噪音之下，
且持續很長的時間，風險就較高。
03:44
for prolonged periods of time.
60
212672
2131
03:47
Noise is stress,
61
215429
1432
噪音是種壓力，
03:48
especially if we have little
or no control over it.

03:51
Our body excretes stress hormones

03:55
that lead to changes
in the composition of our blood
in the composition of our blood
64
223943
2888
它們會改變我們血液的組成，
03:58
and in the structure of our blood vessels,
65
226855
2296
也會改變我們血管的結構，
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
已經證明暴露在噪音中一個晚上，

this still constitutes

71

這仍然會造成重大的公共健康問題，
04:22
because noise is so ubiquitous,
72

2264
因為噪音無所不在，
04:25
and so many people are exposed

04:36
by lowering environmental

04:48
that have been linked to noise exposure,
79
276761
2331
也和噪音暴露有關，
04:51
but we do not have enough evidence yet
80
279116
2167
但我們尚無足夠的證據
04:53
to, in fact, conclude that these diseases
are caused by the noise.
are caused by the noise.
81
281307
4525
能夠下結論說這些疾病
其實就是噪音造成的。

04:59
Yet another important effect of noise
is sleep disturbance.
is sleep disturbance.
82
287062
3491
噪音還有一項重大的影響，
就是睡眠干擾。
就是睡眠干擾。
05:02
Sleep is a very active mechanism
that recuperates us
that recuperates us
83
290577
3038
睡眠是一種非常正面的恢復機制，
讓我們為下一個清醒時段做好準備。
05:05
and prepares us for the next wake period.
84
293639
2413
05:08
A quiet bedroom is a cornerstone
of what sleep researchers call
of what sleep researchers call
85
296555
4143
安靜的臥室可說是基石，
被睡眠研究者稱為
「好的睡眠衛生」。
「好的睡眠衛生」。
05:12
"a good sleep hygiene."
86
300722
1704
05:14
And our auditory system
has a watchman function.
has a watchman function.
87
302968
2940
我們的聽覺系統
有一種夜間看守的功能。
有一種夜間看守的功能。
05:17
It's constantly monitoring
our environment for threats,
our environment for threats,
88
305932
3190
它經常在監控
我們的環境有沒有威脅，
我們的環境有沒有威脅，
05:21
even while we're sleeping.
89
309146
1566
即使我們睡覺時。
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，臥室中的噪音可能
會讓我們延遲進入熟睡。
會讓我們延遲進入熟睡。
05:28
it can wake us up during the night,
91
316732
2422
噪音可能會在大半夜吵醒我們，
05:31
and it can prevent our blood pressure
from going down during the night.
from going down during the night.
92
319178
3715
也可能會制止
我們的血壓在夜間下降。
我們的血壓在夜間下降。
05:35
We have the hypothesis that
if these noise-induced sleep disturbances
if these noise-induced sleep disturbances
93
323266
3389
我們的假設是，
如果這些由噪音造成的打擾
如果這些由噪音造成的打擾
05:38
continue for months and years,
94
326679
2010
持續數個月甚至數年，
05:40
then an increased risk for cardiovascular
disease is likely the consequence.
disease is likely the consequence.
95
328713
4597
後果可能就是
心血管疾病的風險增加。
心血管疾病的風險增加。
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，我們通常沒注意到
這些由噪音造成的睡眠干擾，
這些由噪音造成的睡眠干擾，
05:50
because we are unconscious
while we're sleeping.
while we're sleeping.
97
338170
2539
因為我們在睡覺時是沒有意識的。
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
過去，我們已經研究過
交通噪音對睡眠的影響，
交通噪音對睡眠的影響，
05:57
and research subjects would often
wake up in the morning and say,
wake up in the morning and say,
99
345040
3099
研究受試者通常
會在早上起床時說：
會在早上起床時說：
「啊，昨晚真棒，
我幾乎是立即入睡，
我幾乎是立即入睡，
06:00
"Ah, I had a wonderful night,
I fell asleep right away,
I fell asleep right away,
100
348163
2597
06:02
never really woke up."
101
350784
1733
一覺到天亮。」
06:04
When we would go back
to the physiological signals
to the physiological signals
102
352541
2803
當我們回去看我們在夜間
記錄的生理訊號時，
06:07
we had recorded during the night,
103
355368
1922
06:09
we would often see numerous awakenings
104
357314
2309
我們通常會發現
受試者醒來好幾次，
受試者醒來好幾次，
06:11
and a severely fragmented sleep structure.
105
359647
3046
且睡眠結構很明顯是片段式的。
06:14
These awakenings were too brief
for the subjects to regain consciousness
for the subjects to regain consciousness
106
362717
5513
這幾次醒來的時間都太短暫，
所以受試者不會恢復意識，
06:20
and to remember them
during the next morning,
during the next morning,
107
368254
2891
隔天早上也不會記得有醒來過，
06:23
but they may nevertheless
have a profound impact
have a profound impact
108
371169
3084
但睡眠中途醒來，
免不了會深深影響到
免不了會深深影響到
06:26
on how restful our sleep is.
109
374277
2187
我們睡眠是否能提供充份的休息。
06:30
So when is loud too loud?
110
378273
1913
所以，多大聲才是太大聲？
06:32
A good sign of too loud is
once you start changing your behavior.
once you start changing your behavior.
111
380900
3858
有個很好的徵兆表示聲音太大：
你開始改變你的行為。
你開始改變你的行為。
06:37
You may have to raise your voice
to be understood,
to be understood,
112
385752
2401
你可能得要拉高音量
來讓對方聽懂你的話，
來讓對方聽懂你的話，
06:40
or you increase the volume of your TV.
113
388177
2228
或是你把電視音量轉更大聲。
06:42
You're avoiding outside areas,
or you're closing your window.
or you're closing your window.
114
390849
3030
你會避開外圍的區域，
或是你會把窗戶關上。
或是你會把窗戶關上。
你把你的臥室搬到房子的地下室，
06:46
You're moving your bedroom
to the basement of the house,
to the basement of the house,
115
394356
2656
或是你甚至安裝了隔音牆。
06:49
or you even have
sound insulation installed.
sound insulation installed.
116
397036
2532
06:51
Many people will move away
to less noisy areas,
to less noisy areas,
117
399592
3422
許多人會移動到
比較沒有噪音的地方，
比較沒有噪音的地方，
06:55
but obviously not everybody
can afford that.
can afford that.
118
403038
2486
但顯然不是人人都負擔得起。
06:59
So what can we do right now
to improve our sound environment
to improve our sound environment
119
407508
4045
我們現在能做什麼，
來改善我們的聲音環境，
來改善我們的聲音環境，
07:03
and to better protect our health?
120
411577
2099

當我返回美國並進入機場時，

我就像撞上一道音牆。
08:22
This tells you that
we don't realize anymore

這表示我們已經完全無法發現

the constant degree
of noise pollution we're exposed to

或者使用草耙來取代吹葉機。
08:52
In general, noise reduction at the source
makes the most sense,

because many of the activities

they can expect a certain health effect,

Robert Koch supposedly once said,

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).
