Section 4 You will hear part of a lecture about noise in cities.
2
First, you have some time to look at questions 31 to 40.
3
Thank you.
4
Now listen carefully and answer questions 31 to 40.
5
This lecture will be about the science of acoustics,
6
the study of sound, in relation to urban environments such as cities.
7
As an acoustic engineer myself,
8
I think this is an area where we're likely to see great changes.
9
In the past, researching urban soundscapes was simple.
10
We measured levels of sound in decibels,
11
so I used to take my sound meter and I measured the noise somewhere,
12
and then I might ask a sample of people to say at what level the sound became annoying.
13
With data like this,
14
acoustic engineers have been able to build up what we call noise maps – maps of the sound environment.
15
But actually, these aren't a lot of use.
16
What they do show is that the highest noise levels are generally on roads.
17
Well, that's not really very surprising.
18
But there's quite a lot going on that these maps don't show,
19
because they can't capture the complex way that sound varies over time.
20
So they ignore important issues such as the noise someone might hear from the open windows or gardens of their neighbours.
21
And this sort of noise can be quite significant in summer.
22
We don't have any databases on this sort of information.
23
As well as that, these records of sound levels take no account of the fact
24
that people vary in their perceptions of noise.
25
So someone like me with years of working in acoustics might be very different from you in that regard.
26
But anyway, even though these noise maps are fairly crude,
27
they've been useful in providing information and raising awareness that noise matters.
28
We need to deal with it,
29
and so it's a political matter.
30
And that's important.
31
We need rules and regulations because noise can cause all sorts of problems.
32
Those of you who are city dwellers know that things go on 24 hours a day,
33
so city dwellers often suffer from interrupted sleep.
34
It's also known that noise can lead to a rise in levels of stress
35
due to physical changes in the body affecting the composition of the blood.
36
And there are other problems as well.
37
For instance, if schoolchildren don't have a quiet place to study,
38
their work will suffer.
39
Now one problem with decibel measurement is that it doesn't differentiate between different types of noise.
40
Some types of sounds that most people would probably think of as nice
41
and relaxing might well score quite highly in decibel levels.
42
Think of the sound made by a fountain in a town square, for example.
43
That's not necessarily something that we'd want to control or reduce.
44
So maybe researchers should consider these sorts of sounds in urban design.
45
This is going to be tricky,
46
because just measuring decibel levels isn't going to help us here.
47
Instead, many researchers are using social science techniques,
48
studying people's emotional response to sound by using questionnaires and so on.
49
So what exactly do people want to hear in an urban environment?
50
Some recent interdisciplinary research has come out with results that at first sight seem contradictory.
51
A city needs to have a sense of activity,
52
so it needs to be lively,
53
with sounds like the clack of high heels on a pavement or the hiss of a coffee machine.
54
But these mustn't be too intrusive,
55
because at the same time we need to be able to relax.
56
One of the major problems in achieving this will be getting architects and town planners to use the research.
57
Apart from studying the basics of acoustics,
58
these people receive very little training in this area.
59
But in fact, they should be regarding sound as an opportunity to add to the experience of urban living,
60
whereas at present they tend to see it as something to be avoided or reduced as far as possible,
61
or something that's just a job for engineers,
62
like the street drainage system.
63
What's needed is for noise in cities to be regarded as an aesthetic quality,
64
as something that has the qualities of an art form.
65
If we acknowledge this, then we urgently need to know what governs it and how designers can work with it.
66
We need to develop a complex understanding of many factors.
67
What is the relationship between sound and culture?
68
What can we learn from disciplines such as psychology about the way that sound interacts with human development and social relationships,
69
and the way that sound affects our thoughts and feelings?
70
Can we learn anything from physics about the nature of sound itself?
71
Today's powerful technologies can also help us.
72
To show us their ideas and help us to imagine the effect their buildings will have,
73
architects and town planners already use virtual reality.
74
But these programmes are silent.
75
In the future, such programmes could use realistic sounds,
76
meaning that soundscapes could be explored before being built.
77
So hopefully, using the best technology we can lay our hands on,
78
The city of the future will be a pleasure to the ears as well as the eyes.
79
That is the end of Section 4.
80
You now have half a minute to check your answers.

Thank you.

About This Lesson

In this lesson, learners will engage with a part of a lecture discussing the impact of noise in urban environments, specifically focusing on the scientific study of acoustics. Through this practice, you will enhance your listening and comprehension skills, which are crucial for the IELTS exam. By actively listening to the lecture material, you will also develop your ability to articulate complex ideas and express opinions about noise pollution, an important topic in contemporary discussions about urban living. This practice is aligned with IELTS speaking practice objectives and will contribute to improving your English pronunciation and fluency.

Key Vocabulary & Phrases

  • Acoustics - The science of sound, especially as it relates to the environment.
  • Noise maps - Visual representations of the sound levels in an area.
  • Decibels - A unit used to measure sound intensity.
  • Urban environments - Areas characterized by high human population density and vast human-built environments, such as cities.
  • Interrupted sleep - Sleep that is disturbed or broken, often due to noise.
  • Emotional response - How individuals feel and react emotionally to certain stimuli, like sound.
  • Interdisciplinary research - Research that integrates knowledge and methods from different academic disciplines.

Practice Tips

To maximize your learning experience from this video, consider implementing the shadowing technique, a powerful method for enhancing language skills. Listen to the speaker and try to imitate their pronunciation, intonation, and rhythm as closely as possible. This technique works particularly well with the material presented in this lecture, as the speaker's tone is informative yet engaging, maintaining a moderate pace suitable for shadowing practice.

When using this shadowing site, aim to pause frequently to repeat phrases or sentences, allowing you to concentrate on the nuances of pronunciation and stress patterns. As you shadow the speaker, pay special attention to how they articulate complex terms like "acoustics" and "noise maps." This will not only help you improve your English pronunciation but also foster a deeper understanding of the subject matter, enabling you to discuss noise pollution with confidence during your IELTS speaking practice.

Finally, consider recording yourself while shadowing to analyze your pronunciation and fluency. Listening to your own voice will help you identify areas for improvement, making your practice sessions more effective and focused.

What is the Shadowing Technique?

Shadowing is a science-backed language learning technique originally developed for professional interpreter training and popularized by polyglot Dr. Alexander Arguelles. The method is simple but powerful: you listen to native English audio and immediately repeat it out loud — like a shadow following the speaker with just a 1–2 second delay. Unlike passive listening or grammar drills, shadowing forces your brain and mouth muscles to simultaneously process and reproduce real speech patterns. Research shows it significantly improves pronunciation accuracy, intonation, rhythm, connected speech, listening comprehension, and speaking fluency — making it one of the most effective methods for IELTS Speaking preparation and real-world English communication.
