Take a look around your home.

0:00:030:00:05

Can you be sure that every appliance is safe?

0:00:080:00:11

Is everything a company tells you about a product true?

0:00:130:00:16

And are you getting the best value for your money?

0:00:180:00:20

With the help of the country's top experts,

0:00:220:00:24

we're going to see what it takes to test the household products

0:00:240:00:28

we use every day.

0:00:280:00:30

We'll discover how they're pushed to their limits.

0:00:330:00:36

We'll put the makers' claims on trial.

0:00:370:00:40

And show you how to make your money go further.

0:00:410:00:45

You'll find these products in any ordinary house.

0:00:450:00:48

But THIS is no ordinary house.

0:00:480:00:51

And no ordinary street.

0:00:510:00:53

This is the Watchdog Test House.

0:00:530:00:56

Hello. We're deep inside one of Britain's leading science centres.

0:01:010:01:06

Here at the Building Research Establishment, some of the products

0:01:060:01:10

and materials that we use every day are put to the test

0:01:100:01:14

to make sure that they are safe,

0:01:140:01:16

environmentally friendly and that they don't fall apart.

0:01:160:01:19

Coming up on today's programme:

0:01:200:01:22

Safe as houses?

0:01:220:01:24

What you need to know if you have one of these locks.

0:01:240:01:27

As you can see, it looks like a really secure door,

0:01:270:01:29

but what I'm going to demonstrate is a lock-snapping method.

0:01:290:01:33

Easy as that!

0:01:340:01:36

Beating the burglars,

0:01:360:01:37

the industry experts taking on the most determined housebreakers.

0:01:370:01:42

These headphones claim to cancel out unwanted background noise.

0:01:420:01:46

But how will they cope with this?

0:01:460:01:48

LOUD DRILL

0:01:480:01:50

Plus, quantum leaps in design, exhaustive testing,

0:01:500:01:53

and pressure from Watchdog.

0:01:530:01:55

I'll let you know what happens to this story.

0:01:560:01:59

How it all led to a safer microwave in your kitchen.

0:01:590:02:02

Let's start with the front door.

0:02:080:02:10

There are more than 180,000 burglaries across the UK every year,

0:02:100:02:15

so it's vital that all doors and locks are tested properly

0:02:150:02:19

before they're sold.

0:02:190:02:20

The tests are rigorous.

0:02:200:02:22

But the criminals are becoming ever-more cunning.

0:02:220:02:25

And one of the latest challenges for the security industry

0:02:250:02:28

is lock-snapping.

0:02:280:02:30

It's fast become a nationwide concern.

0:02:300:02:33

A certain type of lock called a Euro cylinder

0:02:330:02:36

fitted to millions of UPVC doors and windows up and down the country

0:02:360:02:40

that can be broken by burglars in seconds.

0:02:400:02:43

A phenomenon known as lock snapping.

0:02:430:02:46

Alan Boylan from Leeds was a recent victim.

0:02:460:02:48

Got up when the alarm went off.

0:02:480:02:50

I assumed that I'd left my lights on and gone to bed leaving them on.

0:02:500:02:54

It were only when I actually got to the kitchen window

0:02:540:02:57

I realised that my conservatory door was wide open.

0:02:570:03:00

As I've opened the inner door to go to the conservatory door

0:03:000:03:03

to see why it was left open, handle fell off in my hand

0:03:030:03:07

and I found that the lock had been damaged on the door.

0:03:070:03:11

It was then that Alan realised intruders had been in his home.

0:03:110:03:15

They'd managed to take his laptop, games console

0:03:150:03:17

and even his car from the driveway, all without waking him.

0:03:170:03:21

That's because the lock snapping technique is quiet, quick

0:03:210:03:24

and all-too easy for burglars in the know.

0:03:240:03:27

Since the burglary, it's affected my family in a bad way,

0:03:270:03:31

especially my wife.

0:03:310:03:33

She can't sleep at night now.

0:03:330:03:34

I have to come home on my break to make sure everything's all right,

0:03:340:03:38

do a full check of the house then go back to work.

0:03:380:03:40

I'd advise anyone who's going to buy a house or who's got these

0:03:400:03:44

locks on the door to remove them and put high security ones in.

0:03:440:03:49

So, what is lock snapping?

0:03:490:03:51

Neil Goldup works for Community Action and Support against Crime,

0:03:510:03:54

or CASAC, a local charity dedicated to improving home security

0:03:540:03:58

in West Yorkshire.

0:03:580:03:59

Today, his company is being paid to replace Alan's locks.

0:03:590:04:02

This is a broken Euro cylinder,

0:04:020:04:04

exactly the same type which would have been fitted to this property.

0:04:040:04:08

The burglars have found a technique,

0:04:080:04:10

it's very quick, quiet and very easy to get through these,

0:04:100:04:13

and these types of lock actually control the mechanism in the door.

0:04:130:04:16

Once they bypass this and get access to the locking mechanism,

0:04:160:04:19

it's quite easy for them to do.

0:04:190:04:21

To show just how vulnerable these locks can be,

0:04:210:04:24

we'll put it to the test.

0:04:240:04:25

Neil's told us he can get through a locked door in a matter of seconds.

0:04:250:04:29

And he's going to prove it.

0:04:290:04:30

As you can see, it looks like a really secure door,

0:04:300:04:33

but I'm going to demonstrate a lock- snapping method. So, here I go.

0:04:330:04:37

We can't show you exactly what Neil's doing, but what we can say

0:04:370:04:41

is that it takes him just eight seconds to break through the door.

0:04:410:04:45

As easy as that!

0:04:450:04:46

OK, so it does involve a certain level of skill and inside knowledge,

0:04:460:04:50

but with the issue of lock-snapping becoming a nationwide problem,

0:04:500:04:54

it was clear something needed to be done.

0:04:540:04:56

So, in 2012, a new design of lock was released onto the market.

0:04:560:05:01

Because of all the hard work CASAC have done over the past seven years

0:05:010:05:05

around this type of attack with police, and British Standards,

0:05:050:05:08

new standards have come out and manufacturers have started to develop

0:05:080:05:12

cylinders and products to withstand this type of attack.

0:05:120:05:16

So, what is this new lock and how rigorously are some doors

0:05:160:05:20

and their locks now tested before they come onto the market?

0:05:200:05:23

Later, we head to the British Standards Institution to find out.

0:05:230:05:28

And we'll also be telling you what YOU can do

0:05:280:05:31

to make sure your home is SAFE.

0:05:310:05:33

Now, headphones, noise cancelling headphones.

0:05:380:05:41

They promise to improve your entire listening experience.

0:05:410:05:45

How?

0:05:450:05:46

By actively drowning out external sounds,

0:05:460:05:49

leaving you in your own private cocoon.

0:05:490:05:52

Nice promise, but how good are they?

0:05:520:05:54

Well, Sophie, let's find out.

0:05:570:05:59

If they live up to their claim, you'll hear your favourite track...

0:06:000:06:04

..and very little else.

0:06:050:06:08

Some headphones simply work to block the noise coming in to our ears,

0:06:080:06:13

but these headphones here go a step further and make use

0:06:130:06:16

of some clever electronic systems to actively cancel that noise out.

0:06:160:06:21

Sounds good in theory,

0:06:210:06:23

I'm interested to see how they work in practice.

0:06:230:06:26

Time to put them to the test.

0:06:260:06:28

We're going to look at three sets of headphones

0:06:280:06:31

bought from the UK's three top online retailers.

0:06:310:06:34

The cheapest we could find, the snappily-named JVC HA-NC80,

0:06:340:06:39

for £30.

0:06:390:06:40

A mid range set, the AKG K490 NC at £150.

0:06:430:06:49

And top of the range set, the Sennheiser MM550-X

0:06:500:06:54

costing a whopping £350.

0:06:540:06:57

They all claim to be able to actively cut out background noise,

0:06:590:07:02

but how well do they actually do the job?

0:07:020:07:04

To find out, we've gathered together some expert ears

0:07:050:07:08

to help put them through their paces.

0:07:080:07:10

Andrew is a music reviewer for Classic Music magazine.

0:07:120:07:15

Yeah, I like the idea of noise cancelling.

0:07:150:07:17

In a city like London, there's so much noise around -

0:07:170:07:20

the traffic and buses and sirens constantly.

0:07:200:07:23

Paul is a second year saxophone student

0:07:250:07:27

at the London School of Contemporary Music.

0:07:270:07:29

I'm looking for a good set of noise cancelling headphones.

0:07:290:07:32

And John is a lecturer in electronic musical composition,

0:07:320:07:36

amongst other things.

0:07:360:07:37

I teach experimental music and sonic art.

0:07:370:07:40

I'm concerned about everyday listening and sound quality a lot.

0:07:400:07:44

For headphones, I look for a really good level of noise reduction.

0:07:440:07:48

So, let's get started.

0:07:480:07:49

We ask the experts to sit in a cafe near a busy street.

0:07:490:07:52

So, how do the headphones perform

0:07:520:07:54

when forced to compete with the incessant din of traffic?

0:07:540:07:58

This is what the road sounds like

0:07:580:08:00

without the noise cancelling feature turned on.

0:08:000:08:03

HUM OF TRAFFIC

0:08:030:08:04

But once it's activated, it sounds like this.

0:08:040:08:07

QUIET PURR

0:08:070:08:10

So, our volunteers will try each headphone in turn,

0:08:100:08:13

listening to the same track at the same volume on the same device.

0:08:130:08:17

It's Rachmaninov Piano concerto number 3 for our classical

0:08:180:08:22

music reviewer, Andrew.

0:08:220:08:24

MUSIC PLAYS

0:08:240:08:26

Some Kraftwerk for our electronica don.

0:08:260:08:29

ELECTRONICA MUSIC

0:08:290:08:31

And a timeless bit of Kool and the Gang for our student.

0:08:310:08:34

# Jungle boogie... #

0:08:340:08:36

They'll mark each set of headphones out of five for sound quality

0:08:360:08:40

and out of five for how well they cancel out the sound of the road.

0:08:400:08:43

For each set, a total of 30 points up for grabs.

0:08:430:08:46

I thought the JVC headphones were the most disappointing, definitely.

0:08:460:08:50

JVCs were the worst for sound cancelling.

0:08:500:08:53

By far the worst performer on this part of the test was indeed

0:08:530:08:56

the cheapest product, the JVC HA-NC80.

0:08:560:08:58

They scored just 11 out of 30.

0:09:010:09:03

Perhaps more of a surprise was the headphones in second place,

0:09:030:09:06

top of the range Seinnheisers.

0:09:060:09:08

Although they did well on noise cancelling ability,

0:09:080:09:11

poor performance on sound quality let them down,

0:09:110:09:14

giving them a score of 20½ out of 30.

0:09:140:09:17

The Seinnheisers have an extremely marked noise cancelling function.

0:09:170:09:21

You really know when it's kicked in and when it's switched off.

0:09:210:09:25

But for me that has a slightly detrimental effect to the

0:09:250:09:28

actual sound of the music.

0:09:280:09:30

Which brings us to our winner in this part of the test,

0:09:300:09:32

our mid-range product, the AKG.

0:09:320:09:34

The AKG were by far the best, the most effective noise reduction.

0:09:360:09:39

Overall, a very impressive sound.

0:09:390:09:42

At £150, they cost £200 less than the most expensive product in our test.

0:09:420:09:48

And yet they scored 13 out of a possible 15 for sound quality

0:09:480:09:52

and 12½ out of 15 for noise cancelling.

0:09:520:09:55

A grand total of 25½ out of 30.

0:09:550:09:58

So, that's part one of the test.

0:09:580:10:00

How will they perform when we give them something else to deal with?

0:10:000:10:04

0:10:050:10:06

MICROWAVE BEEPS

0:10:130:10:15

It's not often a product comes along that revolutionises the way we live.

0:10:150:10:19

The first counter-top microwave was produced in 1967

0:10:190:10:23

and, by the mid-'80s, one in four homes had one.

0:10:230:10:27

But as demand grew, prices dropped and for some models,

0:10:270:10:30

that led to a fall in standards and serious safety issues.

0:10:300:10:35

A good thing Watchdog was around to expose them.

0:10:350:10:37

Here's Lynn Faulds Wood.

0:10:370:10:39

Welcome to Watchdog.

0:10:420:10:43

In tonight's programme, all these people have written to us.

0:10:430:10:48

'It's microwave popcorn.'

0:10:480:10:50

From small problems...

0:10:500:10:52

'Steam!

0:10:520:10:53

'That's scalding hot and could burn small hands

0:10:530:10:56

'that try to take it out of the microwave.'

0:10:560:10:58

..to serious health worries.

0:10:580:11:01

'Nowhere do the standards tell manufacturers

0:11:010:11:03

'they should take a thermometer

0:11:030:11:05

'and check that they are actually killing the bugs in their ovens.'

0:11:050:11:09

Over the years, the microwave oven has had plenty of reasons

0:11:090:11:12

to feature on Watchdog.

0:11:120:11:15

But that certainly hasn't put us off buying them.

0:11:150:11:17

Today, 95% of us have a microwave oven in our home.

0:11:190:11:23

And for people with busy lives they are a great invention.

0:11:230:11:27

So, it's amazing to think the ability to cook using microwaves

0:11:270:11:31

was a discovery that happened completely by chance.

0:11:310:11:35

In 1946, an American engineer, Percy Spencer of Raytheon,

0:11:360:11:41

was testing radar technology when he noticed the microwave radiation

0:11:410:11:45

coming from the device had melted the chocolate in his pocket.

0:11:450:11:50

He'd discovered that low-density microwave energy

0:11:500:11:53

could quickly cook food.

0:11:530:11:55

The way microwaves cook food is as soon as it touches

0:11:550:11:59

something organic such as food,

0:11:590:12:02

it will start vibrating the molecules in that food,

0:12:020:12:05

they cause friction and then cause heat

0:12:050:12:09

and it's that process that cooks the food.

0:12:090:12:11

-ARCHIVE:

-Hamburgers perfectly done in 15 seconds.

0:12:110:12:14

By 1947, the Raytheon company had introduced the world

0:12:140:12:19

to the first microwave oven.

0:12:190:12:21

Although it did cost thousands of dollars and weigh 340 kilos.

0:12:210:12:27

It wasn't until 1967, after 20 years of continued development,

0:12:290:12:34

that the company eventually launched the first counter top microwave oven.

0:12:340:12:39

And by the 1970s, they could be found on every high street in Britain.

0:12:400:12:46

But despite their popularity, people didn't always understand

0:12:460:12:50

how these amazing new machines actually worked.

0:12:500:12:54

There were people who saw these 'microwaves' as alien waves.

0:12:540:13:00

Or if a man stood in front of a microwave oven he'd become sterile,

0:13:000:13:05

or if you stood in front of a microwave while it was cooking,

0:13:050:13:09

some of the waves would actually come out through the oven door

0:13:090:13:12

and cook your own insides.

0:13:120:13:14

But they were all myths.

0:13:140:13:16

Some companies even tried to cash in on our worries,

0:13:180:13:21

selling what Watchdog exposed to be questionable leakage detectors.

0:13:210:13:26

We think these are trading on people's fears

0:13:260:13:28

because leakage just isn't a problem with modern microwaves.

0:13:280:13:32

But along with the myths, there were real dangers.

0:13:320:13:35

We've had a number of letters from people whose microwaves

0:13:350:13:38

have actually caught fire.

0:13:380:13:40

What might not have realised is that lots of bits of the modern

0:13:400:13:44

microwave are actually plastic.

0:13:440:13:46

But the trouble is, the plastic they're using in many of these

0:13:460:13:49

microwaves can be horribly burnt if food in the microwaves catches fire.

0:13:490:13:54

To find out how much damage this could cause,

0:13:540:13:57

Watchdog put it to the test.

0:13:570:14:00

We put a Christmas pudding, typical of the high fat, high sugar foods

0:14:000:14:04

that could catch fire if overcooked, into a microwave oven.

0:14:040:14:08

And then deliberately set the timer to its highest level. The result?

0:14:080:14:13

Well, it was clear to see.

0:14:130:14:14

Those are toxic fumes coming into the kitchen

0:14:160:14:19

and that's the burning plastic also coming down from the roof.

0:14:190:14:22

I don't think there are enough warnings in the instructions

0:14:220:14:26

that this can happen.

0:14:260:14:27

The industry knows some foods catch fire very easily,

0:14:270:14:30

like Christmas puddings and mince pies.

0:14:300:14:32

I'll pass our dossier to the Department of Trade's

0:14:320:14:35

consumer safety unit and I'll let you know what happens to this story.

0:14:350:14:39

A year after that report,

0:14:400:14:41

not only were we still getting reports of microwaves fires,

0:14:410:14:46

but manufacturers were still refusing to take responsibility for them.

0:14:460:14:50

So, we set out to prove it wasn't the fault of our Watchdog viewers and

0:14:500:14:55

others using them, but it was actually down to bad product design.

0:14:550:15:01

Here's what we think is wrong and what we'd like done about it.

0:15:010:15:04

Complaint number one - the timer controls.

0:15:040:15:07

MICROWAVE TIMER DINGS

0:15:070:15:08

'We bought five of the cheaper microwaves on the market

0:15:080:15:11

'and got normal people to try to set the manual timers accurately.

0:15:110:15:15

'They couldn't.'

0:15:150:15:17

Complaint number two - the instruction books.

0:15:190:15:22

Cooking times. The Asaki, for example, doesn't give any at all,

0:15:220:15:26

and the others give conflicting times.

0:15:260:15:28

Some say, if you're doubling the quantities of a recipe,

0:15:280:15:31

double the cooking times. Others say much less than that.

0:15:310:15:34

Now, I think specific cooking times are essential.

0:15:340:15:36

And you might agree after you've seen complaint number three.

0:15:360:15:41

Fire hazards.

0:15:410:15:42

'We, again, showed what could happen if the setting was wrong

0:15:420:15:46

'and overcooked some food.'

0:15:460:15:48

On this one, not only did the food catch fire,

0:15:480:15:51

but the door also blew open, and you can see here the flames

0:15:510:15:54

shooting up between the door and the main body of the oven.

0:15:540:15:57

'This time, the industry DID take notice.

0:15:570:16:00

'And just a month later,

0:16:000:16:02

'the programme was beginning to get results.'

0:16:020:16:05

Since then, Rumbelows, whose brand name is Asaki,

0:16:070:16:09

flew over two senior engineers from their factory in Korea

0:16:090:16:12

to visit us to look at our Watchdog tests.

0:16:120:16:15

As a result, all new Asaki microwave ovens are to have a thermal cut out,

0:16:150:16:19

and they're still looking at the type of plastic they're using.

0:16:190:16:22

'A great result. And others soon followed.'

0:16:220:16:25

Since the 1980s, the microwave industry has made massive strides,

0:16:270:16:32

things like thermal cut outs, better materials, most ovens

0:16:320:16:36

have a stainless steel interior, and all the instructions

0:16:360:16:40

in the manuals are very clear these days, so they're easy to use.

0:16:400:16:44

'So, it just goes to show how, through a series of leaps in design,

0:16:440:16:48

'exhaustive testing and a fair amount of viewer pressure

0:16:480:16:52

'the microwave has become the product we know and use today.

0:16:520:16:56

What do you use to wash your hair? Is it worth spending more

0:17:020:17:06

for a salon formulated shampoo,

0:17:060:17:09

or will an own brand value product work just as well?

0:17:090:17:13

Well, to tell us all about it is hair specialist,

0:17:130:17:16

or consultant trichologist, Iain Sallis.

0:17:160:17:18

Do you actually need to use a shampoo?

0:17:180:17:20

Couldn't you just get away with using some sort of body wash?

0:17:200:17:23

Well, I suppose, yes, you could just use a body wash

0:17:230:17:26

but, for hair, it is better

0:17:260:17:28

if we have more acidic properties to detergents,

0:17:280:17:33

what we call shampoos, because it closes the cuticles down,

0:17:330:17:37

and it makes our hair nice and shiny.

0:17:370:17:39

If you spend more, is it better for your hair?

0:17:390:17:42

It's more to do with the ingredients that's in them.

0:17:420:17:45

If you take the basic shampoos, they will have the basic detergents,

0:17:450:17:50

a foaming agent, preservatives, and perfumes.

0:17:500:17:54

Then you go in to the second bracket,

0:17:540:17:56

which is the mid-range shampoos and they will have

0:17:560:17:59

all the proteins in it, they will have pearlisers

0:17:590:18:03

to make it look nice, it'll have nicer perfumes to make it smell nice.

0:18:030:18:07

The higher range high street brands and the salons

0:18:070:18:10

sort of fall in to that bracket.

0:18:100:18:12

But then you go into the super priced £20-£50 shampoos,

0:18:120:18:18

which really is more to do with marketing.

0:18:180:18:20

The amounts of things that are in there like white truffle oil,

0:18:200:18:24

and caviar, anything else that you can think of,

0:18:240:18:27

they are in such small amounts, it really doesn't make a difference.

0:18:270:18:32

But there are shampoos which are more expensive

0:18:320:18:35

because of the specific ingredient for specific treatments to the scalp.

0:18:350:18:40

So, is the bottom line, stick with what you know

0:18:400:18:42

and go for a mid-range shampoo?

0:18:420:18:44

I think if you avoid the really bargain basement ones,

0:18:440:18:47

if you can, mid-range shampoos are good,

0:18:470:18:51

but after you go up from the £15-£20 mark

0:18:510:18:55

those are the type of shampoos that you start paying for the name,

0:18:550:18:59

the brand. There is a psychosomatic element to this so people

0:18:590:19:05

who pay more expensive shampoos will obviously feel more because

0:19:050:19:08

they won't turn round and go, "That was rubbish,"

0:19:080:19:10

-if they've paid 50 quid for it.

-The feel good factor.

0:19:100:19:13

-Iain Sallis, thank you very much.

-You're welcome.

0:19:130:19:15

Back now to the headphones that claim to block out

0:19:200:19:23

the irritating sounds of the outside world that might otherwise

0:19:230:19:26

spoil your musical enjoyment.

0:19:260:19:28

Earlier, we asked three music buffs to rate the performance and

0:19:280:19:32

quality of three different sets of headphones currently on the market.

0:19:320:19:36

Their first test took place amid the incessant din of busy traffic.

0:19:360:19:40

This time, the headphones have something even louder

0:19:400:19:43

to compete with - roadworks.

0:19:430:19:45

First, a quick reminder of the products in our test.

0:19:470:19:50

The cheapest set of headphones is the JVC HA-NC80.

0:19:500:19:55

These cost just £30

0:19:550:19:57

and, unsurprisingly, performed the worst in our first test.

0:19:570:20:00

I thought the JVC headphones were the most disappointing, definitely.

0:20:000:20:04

The sound was just a bit general, quite hazy.

0:20:040:20:06

Not much definition, not much clarity to it.

0:20:060:20:09

In second place, however,

0:20:090:20:10

were the top of the range product, the Sennheiser MM550-X costing £350.

0:20:100:20:16

But by far the best performer

0:20:170:20:19

when it came to both noise cancelling and sound quality on this test

0:20:190:20:22

was in fact the mid-range headphones, the AKG K490 NC at £150.

0:20:220:20:28

The AKGs were by far the best, the most effective noise reduction.

0:20:280:20:32

Overall, a very impressive sound.

0:20:320:20:35

But now it's time to give them something else to deal with.

0:20:350:20:37

The dulcet tones of major road works.

0:20:390:20:43

Because these headphones are actively cancelling the sound,

0:20:430:20:46

it'll be interesting to see how well they do with

0:20:460:20:49

a sudden change in the outside sound levels.

0:20:490:20:52

For this test we're going to need a workman...

0:20:520:20:54

..and some roadwork sounds.

0:20:560:20:57

PNEUMATIC DRILL ROARS

0:20:570:20:59

We, once again, sit each of our volunteers next to a busy road

0:20:590:21:02

and ask them to mark each set of headphones

0:21:020:21:05

out of five, for sound quality and how well they cancel out the noise.

0:21:050:21:09

Again, a possible 30 points up for grabs.

0:21:090:21:11

Already it's looking like our drilling is proving

0:21:120:21:14

a much tougher challenge.

0:21:140:21:16

The roadworks test was interesting

0:21:160:21:18

because there was an extreme difference in the three headphones.

0:21:180:21:21

Overall, once more, everyone agreed that the mid-range AKG coped

0:21:210:21:25

the best with both noise cancelling and sound quality.

0:21:250:21:28

The AKG headphones seemed to do the best job of

0:21:280:21:32

separating the drill sound from the music.

0:21:320:21:35

Again, the most expensive product did a good job of cutting out

0:21:350:21:38

the noise, but it was at the expense of sound quality,

0:21:380:21:41

with the cheapest, the JVC,

0:21:410:21:43

performing the worst in both categories.

0:21:430:21:46

The JVC seemed to take the bass off but you got this pinging drill noise

0:21:460:21:50

at the top which was, actually, even worse than

0:21:500:21:53

the drill sound in its entirety.

0:21:530:21:56

JVC told us that the headphones we tested, the HA-NC80,

0:21:560:22:01

are their entry level product,

0:22:010:22:03

and they are confident the higher spec products in their range

0:22:030:22:05

would perform better against the other headphones featured in Our test.

0:22:050:22:09

But none of our three products managed to cut out the drilling sound completely.

0:22:090:22:13

So, why did they struggle?

0:22:130:22:15

So sound is made up of waves. A simple sound wave might look...

0:22:150:22:19

something like this.

0:22:190:22:21

What these headphones are trying to do is to cancel that wave

0:22:240:22:28

by generating the opposite wave within your ear.

0:22:280:22:32

So the opposite wave would look just like this.

0:22:320:22:36

And if the headphones get it right, and they generate the opposite wave

0:22:380:22:42

to be perfectly opposite to the original one,

0:22:420:22:45

then what we end up with is a nice, flat, silent sound level.

0:22:450:22:50

When we get a sudden sharp noise, like a roadworks, or similar,

0:22:500:22:55

what happens is, instead of this wave form being nice

0:22:550:22:59

and predictable and steady, the wave form will be going up

0:22:590:23:01

and down very quickly and expanding in and out very quickly.

0:23:010:23:05

And that's much, much harder for the headphones to track

0:23:050:23:08

and to generate the opposite sound.

0:23:080:23:10

But, all in all, it's not a bad attempt

0:23:100:23:13

when you consider all that the modern world has to throw at them.

0:23:130:23:16

I think they're wonderful pieces of equipment.

0:23:160:23:19

It's staggering, in fact, that they can achieve what they do

0:23:190:23:22

if used in the right environment,

0:23:220:23:24

and, as we've seen, that's particularly good

0:23:240:23:26

where there's a nice, constant source of noise.

0:23:260:23:28

We return now to home security.

0:23:320:23:34

and the problems caused by criminals lock snapping. The good news?

0:23:340:23:39

Manufacturers and industry experts

0:23:390:23:41

have been working hard to come up with a solution to reduce the risk

0:23:410:23:45

and to bring greater security to our homes. We've been taking a look.

0:23:450:23:50

The British Standards Institution.

0:23:520:23:54

Here, they test doors and locks on behalf of manufacturers

0:23:540:23:57

to standards way above those that are required by law.

0:23:570:24:00

In fact, they test them

0:24:000:24:02

to their own Kitemark standard, something they call PAS 24.

0:24:020:24:06

It actually takes two days to carry out the full tests.

0:24:060:24:10

So, today Kevin, or Kitemark Kev as he's fondly known, is going

0:24:100:24:14

to take us through some of the highlights,

0:24:140:24:16

on a door we know already meets the all the requirements.

0:24:160:24:19

One of the tests that we have in PAS 24 is the endurance test.

0:24:210:24:24

The endurance test simulates somebody coming in

0:24:240:24:27

and going out of their front door or back door.

0:24:270:24:29

Let me introduce Jeff.

0:24:290:24:31

Jeff is our robot.

0:24:450:24:47

Jeff does all the testing for us. Jeff does 50,000 cycles.

0:24:470:24:51

That's the equivalent of you opening and closing your door

0:24:520:24:55

ten times a day for 14 years.

0:24:550:24:58

Jeff's on...oh, 49,000 cycles so we should probably leave him to it.

0:24:580:25:05

In addition to the endurance test

0:25:120:25:14

we also subject the door to an air test, a rain test,

0:25:140:25:18

and to a wind gusting test.

0:25:180:25:20

We've placed the door into our special weathering test rig

0:25:200:25:23

and we're just about to do an air test on the product.

0:25:230:25:26

In order to pass this test, the door needs to be able to

0:25:280:25:31

withstand 300 pascals, a measure of air pressure,

0:25:310:25:34

on the outside without too much leaking through to the inside.

0:25:340:25:38

This one's passed with ease. So it's onto the rain test.

0:25:380:25:41

We have simulated rain pouring on the outside of the door,

0:25:530:25:56

and we're going to slowly increase the pressure in our test rig

0:25:560:25:59

to simulate lighter winds, and then we're going to look for leakage.

0:25:590:26:03

So far, so good.

0:26:040:26:06

The door's already survived some pretty extreme weather conditions.

0:26:070:26:11

Meanwhile, Jeff's still doing his thing.

0:26:110:26:14

Now it's time for the security tests.

0:26:140:26:17

What we're going to do is a number of different tests on the door

0:26:170:26:20

to simulate an opportunist burglar attacking the door,

0:26:200:26:22

attacking your home.

0:26:220:26:23

The tests range from trying to lever the door open, to smashing it

0:26:260:26:29

with a battering ram.

0:26:290:26:31

All designed to simulate the pressure a burglar might

0:26:310:26:33

put on your door when trying to break in.

0:26:330:26:36

Most of the tests we've done so far have been based on machines.

0:26:360:26:38

The next test is a manual attack test. We're going to attack

0:26:380:26:42

the door using another one of our members of the team.

0:26:420:26:44

You've met Jeff, now meet Dave.

0:26:440:26:46

Dave, you have three minutes, do your best.

0:26:470:26:50

Or your worst.

0:26:500:26:51

We can't show you exactly what Dave is up to,

0:26:530:26:55

safe to say though, he's really going for it.

0:26:550:26:58

But the door is up to the challenge.

0:26:580:27:00

OK, so this test has now been completed,

0:27:000:27:03

and Dave is still on the outside of the door,

0:27:030:27:05

so on the outside of the house,

0:27:050:27:07

so this door has passed this particular test.

0:27:070:27:09

The door is doing well so far.

0:27:090:27:11

But, as we saw earlier, there is one way a burglar can get through

0:27:110:27:15

some UPVC doors in just eight seconds - lock snapping.

0:27:150:27:19

As easy as that.

0:27:200:27:22

So after manufacturers developed a new type of lock designed

0:27:220:27:25

to withstand this kind of attack, the police asked Kevin and his team

0:27:250:27:28

to help devise a new standard in order to test it.

0:27:280:27:32

We've written a standard called TS007,

0:27:320:27:34

and what you're going to see in a few moments is one of our guys

0:27:340:27:38

using those attack methods to demonstrate the product

0:27:380:27:41

that meets those requirements actually will keep the burglar out.

0:27:410:27:45

Dave, have a go.

0:27:450:27:47

And it's clear, this lock is more than up to the job.

0:27:510:27:55

No way.

0:27:550:27:57

There are locks that comply to this new standard currently

0:27:570:28:00

on the market, but if you wish to keep your home safe in the meantime,

0:28:000:28:04

make sure you put bolts down, if you've got them,

0:28:040:28:07

double lock, if you can, and, when leaving the house,

0:28:070:28:10

make sure it looks like someone's at home.

0:28:100:28:13

Security lights or a timer are a good way to do this.

0:28:130:28:16
