- Neil, I'm going to play you two sound recordings
- and I want you to tell me
- how you feel when you hear them.
- OK. First this.
- And now this.
- Oh well, that first clip made me feel really relaxed.
- But the second one, oh it's horrible!
- I felt quite stressed out actually.
- Oh no! Well, this little experiment shows
- how much we are affected by the noise around us.
- And that's a problem if you're one of the four
- billion people around the world who live in cities.
- Yes, whether it's the rattle of train tracks,
- honking car horns or the roar of airplanes overhead,
- modern cities are full of noise.
- And this can have serious effects.
- The World Health Organisation reports that by 2050,
- around 2.5 billion people will experience hearing loss
- and exposure to loud noise has been linked to stress and anxiety.
- In this episode, we'll be hearing about ways
- to make our cities quieter, more relaxing places
- using some useful new words and phrases.
- But now I have a question for you, Georgie.
- Sound is measured in units called decibels.
- But how many decibels would it be if I whispered?
- A whisper is speaking like this.
- Is it a 3 decibels, b 13 decibels
- or c 30 decibels? Oh, that's really hard.
- I'll go for b 13 decibels.
- Well, we'll find out the answer at the end of the programme.
- Let's start in one of the noisiest cities
- in the world, Mumbai in India,
- where daytime noise levels regularly hit 80 decibels,
- which is over 20 decibels higher than World Health Organisation recommendations.
- Listen to Mumbai native Chavi Sachdev
- share her experiences of living in this noisy city
- with BBC World Service programme People Fixing the World.
- I mean, India in general is just really loud.
- We are a loud people.
- We dress loud. We talk loud.
- We celebrate loud. We watch movies loud.
- When people ask me what I miss about living abroad,
- I tell them it's the quiet
- because after 12 years of living in the U.S.
- And Europe, When I got back,
- I realised I couldn't handle it anymore.
- I'd gotten used to lower levels of noise.
- Chavi says Indians talk loud, celebrate loud and dress loud.
- To dress loud means to wear clothes
- with bright colours and large, bold patterns.
- When Chavi returned to India after living overseas,
- she says she couldn't handle the noise.
- If you can't handle something, you find it difficult to deal
- or cope with. So what can be done
- to tackle noise in cities like Mumbai?
- One interesting approach involves using sound itself to make things feel quieter.
- Soundscaping is the idea of adding certain sounds to busy public spaces
- so that they sound and feel more relaxing.
- Sound artist Charles Montembeau lives near the Parc de Madelinot,
- a busy city park in Montreal, Canada.
- Charles was inspired to recreate the ocean sounds he heard on holiday
- in the Magdalen Islands in his city park back home.
- On BBC World Service programme People Fixing the World,
- he tells reporter Natasha Fernandes that these sounds
- included ocean waves and some unusual sounding sand.
- The sand and the Magdalen Island can sing.
- When you walk into the sounds firmly,
- the sand makes some squeaky sounds.
- So that's one sound that is kind of funny, kind of special.
- Inside this small park, surrounded by busy roads,
- Charles and his team set up an immersive sound installation
- in the form of speakers planted in flower beds.
- So the installation was really to make this park
- a little quieter by adding some quiet noises.
- It's counterintuitive, but you can make a park
- less noisy by adding some calmer sounds.
- The sand on the Magdalen Islands is squeaky.
- It makes a high-pitched sound called a squeak
- when stepped on. Charles played recordings of this sand,
- ocean waves and other relaxing sounds through speakers hidden in the park.
- He created an art installation, a work
- of art designed to give people an interactive experience.
- By adding more relaxing sounds, Charles'
- installation actually made the park feel quieter.
- It's an example of something that's counter-intuitive,
- meaning it happens differently from how you would expect.
- What a great idea!
- And similar soundscapes are now helping city dwellers
- relax in other cities too, including Tokyo and Barcelona.
- Now, Neil, you asked me a question
- about a very quiet sound a whisper.
- So, are you going to reveal the correct answer?
- I asked you how loud a whisper
- is. Yes, and I said 13 decibels.
- Well, 13 is an unlucky number and you are wrong.
- It was actually 30.
- OK, let's recap the vocabulary we've learned,
- starting with decibel, the unit for measuring sound.
- Someone who dresses loud likes to wear
- clothes with bright colours and bold designs.
- If you can't handle something, you find it difficult
- to deal with. An art installation is an artwork
- designed to create an interactive experience in a certain space.
- The adjective squeaky describes things which make
- a high-pitched sound, like a mouse. Squeak, squeak!
- And finally, if you call something counter-intuitive,
- you mean it happens differently from how you would expect.
