因為不好的音響效果，學生們在教室裡只聽到老師說的 50% 的內容，而病人在醫院裡也因為長期感到緊張難以入睡。Julian Treasure 呼籲設計師們應該要用實際行動關注聲音這個「隱形的建築設計」。

00:16
It's time to start designing for our ears.
0
1050
3791
是時候開始為我們的耳朵而設計了(聽覺)。
00:20
Architects and designers tend to focus
1
4841
2080
建築師與設計師們似乎有個趨勢
00:22
exclusively on these.
2
6921
1526
都專注設計給這個 - (眼睛，視覺)。
00:24
They use these to design with and they design for them,
3
8447
3114
他們以視覺為考量去設計出一些只著重視覺觀感的設計，
00:27
which is why we end up sitting in restaurants that look
4
11561
2328
這也是為什麼餐廳看起來像這樣
00:29
like this — (loud crowd noise) — and sound like this,
5
13889
1797
但聽起來卻是這樣(吵雜聲)，
00:31
shouting from a foot away to try and be heard
6
15686
2547
必須大聲說話，試圖讓距離一尺外
00:34
by our dinner companion,
7
18233
1302
共進晚餐的朋友聽見，
00:35
or why we get on airplanes -- (flight attendant announcements) -- which cost 200 million pounds,
8
19535
3223
又或者為什麼在造價 2 億的飛機上 (空服員廣播聲)
00:38
with somebody talking through an old-fashioned telephone handset
9
22758
3843
卻聽到這樣經由老式話筒接收
00:42
on a cheap stereo system,
10
26601
1536
再由廉價的立體聲系統傳出的廣播，
00:44
making us jump out of our skins.
11
28137
2653
十分令人感到不舒服。
00:46
We're designing environments that make us crazy. (Laughter)
12
30790
3384
我們正設計些會讓我們發瘋的環境。 (笑聲)
00:50
And it's not just our quality of life which suffers.
13
34174
2712
這不只是降低我們的生活品質。
00:52
It's our health,
14
36886
1775
我們的健康，
00:54
our social behavior, and our productivity as well.
15
38661
4011
我們的社會行為以及我們的生產力都會受到影響。
00:58
How does this work? Well, two ways.
16
42672
1642
這是為什麼呢? 原因可分為兩方面。
01:00
First of all, ambience. I have a whole TEDTalk about this.
17
44314
3439
首先，週遭環境。 這部份在我另一個 TED 演講中有較完整的說明。
01:03
Sound affects us physiologically, psychologically,
18
47753
3431
聲音無時無刻都影響著我們的生理、心理、
01:07
cognitively and behaviorally all the time.
19
51184
2200
我們的認知以及我們的行為。
01:09
The sound around us is affecting us
20
53384
1737
即使我們沒有意識到，
01:11
even though we're not conscious of it.
21
55121
2322
我們周圍的聲音還是影響著我們。
01:13
There's a second way though, as well.
22
57443
1756
再來就是第二方面 - 干擾。
01:15
That's interference. Communication requires sending
23
59199
3377
溝通必須有傳送以及接收，
01:18
and receiving, and I have another whole TEDTalk
24
62576
3900
這我也在另一個 TED 演講中講到
01:22
about the importance of conscious listening,
25
66476
2464
有意識的聆聽的重要性，
01:24
but I can send as well as I like,
26
68940
2034
但即使我可以好好把訊息傳遞出去
01:26
and you can be brilliant conscious listeners.
27
70974
2414
而你也做為一個很好的有意識的聆聽者，
01:29
If the space I'm sending it in is not effective,
28
73388
3500
只要我們所處的空間環境不理想
01:32
that communication can't happen.
29
76888
2494
就無法有效地溝通。
01:35
Spaces tend to include noise and acoustics.
30
79382
2530
空間包括噪音以及音響效果。
01:37
A room like this has acoustics, this one very good acoustics.
31
81912
3700
像這個場地有很好的音響效果。
01:41
Many rooms are not so good.
32
85612
2168
很多其他場地的音響效果就沒這麼好了。
01:43
Let me give you some examples from a couple of areas
33
87780
2031
讓我舉幾個例子來說 --
01:45
which I think we all care about: health and education.
34
89811
3473
我想這是大家都關心的領域：健康和教育。
01:49
(Hospital noises) When I was visiting my terminally ill father
35
93284
2232
(醫院的噪音) 當我到醫院探望我病危的父親時
01:51
in a hospital, I was asking myself,
36
95516
2032
我問了自己一個問題 --
01:53
how does anybody get well in a place that sounds like this?
37
97548
4137
人們怎麼能在這樣的環境中康復呢?
01:57
Hospital sound is getting worse all the time.
38
101685
2308
醫院的噪音愈來愈嚴重。
01:59
Noise levels in hospitals have doubled
39
103993
2006
在過去幾年醫院的噪音程度翻了一倍，
02:01
in the last few years, and it affects not just the patients
40
105999
3604
這不只是影響病人，
02:05
but also the people working there.
41
109603
1816
也影響到在醫院工作的人。
02:07
I think we would like for dispensing errors to be zero,
42
111419
3877
我們都希望配藥出錯率為零
02:11
wouldn't we? And yet, as noise levels go up, so do
43
115296
3465
不是嗎? 然而隨著噪音程度的上升，
02:14
the errors in dispensing made by the staff in hospitals.
44
118761
3554
醫院員工的配藥出錯率也會上升。
02:18
Most of all, though, it affects the patients,
45
122315
3055
首當其衝的還是病人，
02:21
and that could be you, it could be me.
46
125370
2208
而這可能會是你也可能會是我。
02:23
Sleep is absolutely crucial for recovery.
47
127578
2339
睡眠是康復過程中最重要的一環。
02:25
It's when we regenerate, when we rebuild ourselves,
48
129917
3040
是我們再生、自我復原的時候，
02:28
and with threatening noise like this going on,
49
132957
2384
然而在這種吵雜的環境下
02:31
your body, even if you are able to sleep, your body
50
135341
3152
就算你可以睡得著，你的身體也會告訴你
02:34
is telling you, "I'm under threat. This is dangerous."
51
138493
3043
「我正受到威脅、這裡是危險的。」
02:37
And the quality of sleep is degraded, and so is our recovery.
52
141536
3229
於是睡眠的品質下降了，康復的速度也下降了。
02:40
There are just huge benefits to come
53
144765
2152
以聽覺的角度進行設計
02:42
from designing for the ears in our health care.
54
146917
3037
只會為我們的醫療保健帶來極大的益處。
02:45
This is an area I intend to take on this year.
55
149954
2907
這是我今年打算涉及的領域：
02:48
Education.
56
152861
1965
教育。
02:50
When I see a classroom that looks like this,
57
154826
1596
當我看到像這樣的教室，
02:52
can you imagine how this sounds?
58
156422
1877
你能想像上課聽起來怎樣嗎?
02:54
I am forced to ask myself a question.
59
158299
2331
我不禁問自己一個問題：
02:56
("Do architects have ears?") (Laughter)
60
160630
2577
(「建築師們有耳朵嗎?」) (笑聲)
02:59
Now, that's a little unfair. Some of my best friends
61
163207
2667
這樣說有點不公平，畢竟我有一些摯友就是建築師，
03:01
are architects. (Laughter) And they definitely do have ears.
62
165874
2889
(笑聲) 而他們也都有耳朵。
03:04
But I think sometimes they don't use them
63
168763
2065
但我覺得有時候他們在設計時並沒有考量到耳朵的部份。
03:06
when they're designing buildings. Here's a case in point.
64
170828
2663
這就是個實際的例子。
03:09
This is a 32-million-pound flagship academy school
65
173491
3691
這是一所耗資 3200 萬英鎊的旗艦學校，
03:13
which was built quite recently in the U.K. and designed
66
177182
2005
最近剛在英國落成
03:15
by one of Britain's top architects.
67
179187
3147
而且是由一位英國頂尖的建築師設計的。
03:18
Unfortunately, it was designed like a corporate
68
182334
1825
不幸的是，它被設計的像個企業總部，
03:20
headquarters, with a vast central atrium
69
184159
2399
有個大型的中庭，
03:22
and classrooms leading off it with no back walls at all.
70
186558
4274
然後教室緊接著中庭而且沒有背牆。
03:26
The children couldn't hear their teachers.
71
190832
1926
孩子們根本聽不到老師在講什麼。
03:28
They had to go back in and spend 600,000 pounds
72
192758
2721
後來只好又花了 60 萬英鎊加建背牆。
03:31
putting the walls in. Let's stop this madness
73
195479
3080
請停止這種開放式教室瘋狂的設計吧!
03:34
of open plan classrooms right now, please.
74
198559
4062
拜託，請立刻停止吧!
03:38
It's not just these modern buildings which suffer.
75
202621
3528
不只這種新式設計有問題，
03:42
Old-fashioned classrooms suffer too.
76
206149
2337
舊式的教室也有這種問題。
03:44
A study in Florida just a few years ago found
77
208486
2194
在一個佛羅里達州沒幾年前的研究發現
03:46
that if you're sitting where this photograph was taken
78
210680
1677
如果你坐在拍攝這張照片的地方 -- 第四排，
03:48
in the classroom, row four, speech intelligibility
79
212357
3200
語言的辨別理解度
03:51
is just 50 percent.
80
215557
2451
僅剩下 50%。
03:53
Children are losing one word in two.
81
218008
2200
孩子們只能聽到一半的內容。
03:56
Now that doesn't mean they only get half their education,
82
220208
2645
當然這不代表他們只接受到一半的教育，
03:58
but it does mean they have to work very hard
83
222853
1712
但卻表示他們必須花更多心力
04:00
to join the dots and understand what's going on.
84
224565
2976
把前後連貫才有辦法理解內容。
04:03
This is affected massively by reverberation time,
85
227541
2773
這絕大部分是受到回響的時間影響，
04:06
how reverberant a room is.
86
230314
1900
看這個空間的回響程度而定。
04:08
In a classroom with a reverberation time of 1.2 seconds,
87
232214
3558
在一個回響時間 1.2 秒的教室中 -- 這是很常見的情況，
04:11
which is pretty common, this is what it sounds like.
88
235772
3696
聲音聽起來是像這樣的。
04:15
(Inaudible echoing voice)
89
239468
12304
(無法辨別、有回響的語音)
04:27
Not so good, is it?
90
251772
1817
不是很好，對吧?
04:29
If you take that 1.2 seconds down to 0.4 seconds
91
253589
4459
如果藉由裝設一些改善音響效果的裝置、
04:33
by installing acoustic treatments, sound absorbing materials
92
258048
2948
吸音材料等，將回響時間由 1.2 秒降到 0.4 秒，
04:36
and so forth, this is what you get.
93
260996
2708
可以得到這樣的結果。
04:39
Voice: In language, infinitely many words can be written
94
263704
3861
語音：在語言中，由一小組的字母
04:43
with a small set of letters. In arithmetic,
95
267565
2872
就可以寫出無限多的詞彙。
04:46
infinitely many numbers can be composed
96
270437
2354
在數學中，由幾個數字再加上 "0"
04:48
from just a few digits with the help of the simple zero.
97
272791
3602
就可以組合成無限多個數值。
04:52
Julian Treasure: What a difference.
98
276393
1564
Julian Treasure: 如此大的差異。
04:53
Now that education you would receive,
99
277957
1840
這樣的教育你就可以接收到了。
04:55
and thanks to the British acoustician Adrian James
100
279797
2930
剛才的情況模擬是由英國聲學專家 Adrian James 所提供。
04:58
for those simulations. The signal was the same,
101
282727
2689
在剛才的兩個情況中，
05:01
the background noise was the same.
102
285416
1399
聲音訊號以及背景噪音都沒有變動。
05:02
All that changed was the acoustics of the classroom
103
286815
2443
唯一改變的就只有
05:05
in those two examples.
104
289258
1674
教室的音響效果。
05:06
If education can be likened to watering a garden,
105
290932
2420
如果把教育比喻作在花園澆水 -- 這是蠻合理的比喻，
05:09
which is a fair metaphor, sadly, much of the water
106
293352
4167
很遺憾的，大部分的水分
05:13
is evaporating before it reaches the flowers,
107
297519
3056
在澆到花之前就蒸發掉了，
05:16
especially for some groups,
108
300575
2032
這情形對某些類別的人更是如此，
05:18
for example, those with hearing impairment.
109
302607
3376
例如: 聽力受損的人。
05:21
Now that's not just deaf children. That could be any child
110
305983
2752
這不只是指失聰的孩子，還包括感冒、
05:24
who's got a cold, glue ear, an ear infection,
111
308735
2435
漿液性中耳炎、耳道感染甚至花粉症的孩子。
05:27
even hay fever. On a given day, one in eight children
112
311170
2376
任一天，每八個孩子就有一個
05:29
fall into that group, on any given day.
113
313546
2816
是以上這個類別的人。
05:32
Then you have children for whom English is a second language,
114
316362
3176
再加上英語為第二語言的孩子
05:35
or whatever they're being taught in is a second language.
115
319538
2936
或是以任何第二語言學習的孩子。
05:38
In the U.K., that's more than 10 percent of the school population.
116
322474
3584
在英國就有超過 10% 的孩子是如此。
05:41
And finally, after Susan Cain's wonderful TEDTalk in February,
117
326058
3660
最後，在聽過 Susan Cain 在二月份精彩的 TED 演講之後，
05:45
we know that introverts find it very difficult to relate
118
329718
3216
我們知道生性內向的人很難在吵雜的環境中
05:48
when they're in a noisy environment doing group work.
119
332934
2697
在團體作業中取得共鳴。
05:51
Add those up. That is a lot of children
120
335631
2661
以上這些加總起來。實在很多孩子
05:54
who are not receiving their education properly.
121
338292
2412
都沒有確實地接受到完整的教育。
05:56
It's not just the children who are affected, though.
122
340704
2236
然而，不只是孩子們受到影響。
05:58
(Noisy conversation) This study in Germany found
123
342940
1583
(吵雜的對話聲) 這個在德國的研究發現
06:00
the average noise level in classrooms is 65 decibels.
124
344523
3555
教室中平均的噪音程度是 65 分貝。
06:03
I have to really raise my voice to talk over 65 decibels
125
348078
4226
我必須提高我的音量才有辦法在 65 分貝的環境中被聽到，
06:08
of sound, and teachers are not just raising their voices.
126
352304
3784
而老師們也不只是提高他們的音量。
06:11
This chart maps the teacher's heart rate
127
356088
2808
這個圖表對照出老師的心跳速率
06:14
against the noise level.
128
358896
2424
跟噪音程度的關係。
06:17
Noise goes up, heart rate goes up.
129
361320
2707
噪音程度提升時心跳速率也會上升。
06:19
That is not good for you.
130
364027
2149
這對身體是不好的。
06:22
In fact, 65 decibels is the very level at which this big survey
131
366176
4080
事實上，在這個噪音與健康的研究中也指出，
06:26
of all the evidence on noise and health found that, that is
132
370256
3528
65 分貝也正好是噪音誘發心肌梗塞
06:29
the threshold for the danger of myocardial infarction.
133
373784
4707
的閾值 (臨界值)。
06:34
To you and me, that's a heart attack.
134
378491
2849
對你我來說，就是指心臟病。
06:37
It may not be pushing the boat out too far to suggest
135
381340
2719
我們甚至可以說，老師們
06:39
that many teachers are losing significant life expectancy
136
384059
4300
每天在這樣的環境中教學
06:44
by teaching in environments like that day after day.
137
388359
4272
就是在縮短他們的壽命。
06:48
What does it cost to treat a classroom
138
392631
2056
把教室的回響時間降到 0.4 秒
06:50
down to that 0.4-second reverberation time?
139
394687
2770
到底要花多少錢呢?
06:53
Two and a half thousand pounds.
140
397457
2734
2,500 英鎊。
06:56
And the Essex study which has just been done in the U.K.,
141
400191
3176
剛在英國艾塞克斯 (Essex) 完成的一個研究指出，
06:59
which incidentally showed that when you do this,
142
403367
2341
這樣的改造不只是
07:01
you do not just make a room that's suitable
143
405708
2363
創造一個更適合那些聽力受損孩子的環境，
07:03
for hearing-impaired children, you make a room
144
408071
1597
更可以顯著提升孩子們的
07:05
where behavior improves, and results improve significantly,
145
409668
5284
行為表現以及學習成效。
07:10
this found that sending a child out of area to a school
146
414952
3992
研究也指出，如果學校沒有這樣的教室環境
07:14
that does have such a room, if you don't have one,
147
418944
2631
而把孩子送到別區中有這樣教室環境的學校，
07:17
costs 90,000 pounds a year.
148
421575
3462
每年需花費 90,000 英鎊。
07:20
I think the economics are pretty clear on this.
149
425037
2387
我想，這從經濟的角度來看也很清楚了吧。
07:23
I'm glad that debate is happening on this.
150
427424
2019
我很高興人們開始思考、討論這個議題。
07:25
I just moderated a major conference in London
151
429443
2566
幾個禮拜前我在倫敦 (London) 主持了一個
07:27
a few weeks ago called Sound Education,
152
432009
2049
大型會議，主題是「聲音教育」，
07:29
which brought together top acousticians,
153
434058
1797
吸引了許多頂尖聲學專家、
07:31
government people, teachers, and so forth.
154
435855
2021
政府人員及老師等來參與。
07:33
We're at last starting to debate this issue, and the benefits
155
437876
4199
我們終於開始探討這個議題，
07:37
that are available for designing for the ears in education,
156
442075
2700
而在教育的部份，為耳朵 (聽覺) 的設計所帶來益處
07:40
unbelievable.
157
444775
1811
是非常驚人的。
07:42
Out of that conference, incidentally, also came
158
446586
3069
這場會議也偶然地帶來了一款免費的程式，
07:45
a free app which is designed to help children study
159
449655
3002
專門設計來幫助孩子
07:48
if they're having to work at home, for example,
160
452657
2371
在家裡吵雜的環境中 (如廚房)
07:50
in a noisy kitchen.
161
455028
1592
學習。
07:52
And that's free out of that conference.
162
456620
3238
這套軟體是免費的。
07:55
Let's broaden the perspective a little bit
163
459858
2951
讓我們放寬我們的焦點
07:58
and look at cities.
164
462809
1411
看到了城市。
08:00
We have urban planners.
165
464220
2492
我們有都市計劃的人員。
08:02
Where are the urban sound planners?
166
466712
3145
那都市聲音規劃的人員呢?
08:05
I don't know of one in the world, and the opportunity is there
167
469857
3207
我從未遇到過一個，而我們也確實有這個機會
08:08
to transform our experience in our cities.
168
473064
2536
可以改善居住在都市中的經驗品質。
08:11
The World Health Organization estimates
169
475600
2107
世界衛生組織 (WHO) 估計
08:13
that a quarter of Europe's population is having its sleep
170
477707
2584
有 1/4 歐洲人口因為都市的噪音導致睡眠品質的下降。
08:16
degraded by noise in cities. We can do better than that.
171
480291
3933
這都是我們可以改善的。
08:20
And in our offices, we spend a lot of time at work.
172
484224
2829
又例如我們的辦公室，我們花很多時間在那工作。
08:22
Where are the office sound planners?
173
487053
2659
那辦公室聲音規劃的人員呢?
08:25
People who say, don't sit that team next to this team,
174
489712
1887
有人會說，不要把這兩組人排在一起
08:27
because they like noise and they need quiet.
175
491599
2333
因為一組喜歡喧鬧另一組喜歡安靜。
08:29
Or who say, don't spend all your budget on a huge screen
176
493932
2739
也有人會說，不要把預算全部
08:32
in the conference room,
177
496671
943
花在會議室的大螢幕然後
08:33
and then place one tiny microphone
178
497614
2009
只在 30 人的會議桌中央
08:35
in the middle of a table for 30 people. (Laughter)
179
499623
3237
裝設一支小小的麥克風。 (笑聲)
08:38
If you can hear me, you can understand me
180
502860
2119
如果你可以聽清楚我說的話，不需要看到我就可以
08:40
without seeing me. If you can see me without hearing me,
181
504979
3125
了解我想表達的事情。但如果你只看的到我卻聽不到，
08:44
that does not work.
182
508104
2104
這是沒有用的。
08:46
So office sound is a huge area, and incidentally,
183
510208
3216
所以我們知道辦公室的聲音效果很重要，
08:49
noise in offices has been shown to make people
184
513424
2136
湊巧的是，辦公室的噪音也讓人變得冷漠、
08:51
less helpful, less enjoy their teamwork,
185
515560
2623
變得較無法享受團隊工作的樂趣
08:54
and less productive at work.
186
518183
2521
以及使生產力下降。
08:56
Finally, we have homes. We use interior designers.
187
520704
3053
最後，看到我們的居家環境。我們有室內設計師。
08:59
Where are the interior sound designers?
188
523757
2235
但室內聲音規劃的人員呢?
09:01
Hey, let's all be interior sound designers,
189
525992
3340
讓我們都來做室內聲音的規劃吧，
09:05
take on listening to our rooms and designing sound
190
529332
2817
讓我們開始聆聽我們的房間並設計一個讓聲音可以
09:08
that's effective and appropriate.
191
532149
1518
適當、有效地傳遞的空間吧。
09:09
My friend Richard Mazuch, an architect in London,
192
533667
2541
我的朋友 Richard Mazuch，一名倫敦的建築師，
09:12
coined the phrase "invisible architecture."
193
536208
2886
創造了一個詞「隱形的建築設計」。
09:14
I love that phrase.
194
539094
1550
我太愛這個詞了。
09:16
It's about designing, not appearance, but experience,
195
540644
5080
它是指關注實際體驗、感受的設計而非只注重外表，
09:21
so that we have spaces that sound as good as they look,
196
545724
3608
這樣才能讓空間的視覺效果跟聽覺效果兼具，
09:25
that are fit for purpose, that improve our quality of life,
197
549332
3510
讓空間可以符合規劃的用途、提升我們的生活品質及健康、
09:28
our health and well being, our social behavior
198
552842
3241
提升我們的社會行為
09:31
and our productivity.
199
556083
1876
以及我們的生產力。
09:33
It's time to start designing for the ears.
200
557959
3506
是時候開始為我們的耳朵而設計了(聽覺)。
09:37
Thank you. (Applause)
201
561465
2830
謝謝。(掌聲)
09:40
(Applause)
202
564295
1532
(掌聲)
09:41
Thank you. (Applause)
203
565827
4756
謝謝。(掌聲)
