Keywords

💡Потеря слуха

Потеря слуха — это ухудшение способности воспринимать звуки, которое может варьироваться от легкого до тяжелого. В видео подчеркивается, что потеря слуха является глобальной проблемой, затрагивающей миллионы людей, и может возникать как от длительного воздействия шума, так и от других факторов. Пример из видео: около 1,15 миллиарда человек страдают легкой степенью потери слуха.

💡Аудиограмма

Аудиограмма — это графическое отображение результатов теста слуха, показывающее, какие частоты человек может слышать и на каком уровне громкости. В видео аудиограмма используется для объяснения, как определяется степень потери слуха у человека. Пример из видео: тест слуха позволяет определить порог восприятия для каждой частоты звука.

💡Тиннитус

Тиннитус — это постоянный звон в ушах, который может возникнуть после длительного воздействия громких звуков. В видео упоминается, что это явление может быть одним из первых признаков повреждения слуха. Пример из видео: после нахождения в шумной обстановке без защиты слуха у людей часто возникает тиннитус.

💡Шумоподавление

Шумоподавление — это технология, используемая в некоторых наушниках, которая нейтрализует окружающий шум путем создания звуковой волны, противоположной по фазе. В видео автор объясняет, что наушники с активным шумоподавлением могут помочь защитить слух, снижая потребность в повышении громкости музыки. Пример из видео: автор начал использовать наушники с шумоподавлением и заметил уменьшение уведомлений о высоком уровне шума.

💡Децибелы

Децибелы — это единицы измерения уровня громкости звука. В видео подчеркивается, что увеличение громкости на несколько децибел не является линейным процессом: даже небольшое увеличение может значительно повысить уровень шума и негативно сказаться на слухе. Пример из видео: разница между 90 и 100 децибелами кажется небольшой, но на практике это огромный скачок по интенсивности звука.

💡Звуковые волны

Звуковые волны — это колебания воздуха, которые воспринимаются нашими ушами как звуки. В видео показано, как звуковые волны воздействуют на волосковые клетки в ухе, вызывая их колебания, что позволяет мозгу воспринимать звук. Пример из видео: повреждение волосковых клеток может привести к необратимой потере слуха.

💡Волосковые клетки

Волосковые клетки — это чувствительные клетки в улитке внутреннего уха, которые преобразуют звуковые колебания в нервные сигналы для передачи в мозг. В видео объясняется, что постоянное воздействие громкого шума может повредить эти клетки, что приводит к необратимой потере слуха. Пример из видео: автор описывает, как волосковые клетки изгибаются и повреждаются под воздействием громких звуков.

💡Экономическое воздействие

Экономическое воздействие — это финансовые потери, связанные с последствиями потери слуха, как для отдельных людей, так и для общества в целом. В видео упоминается, что потеря слуха может значительно повлиять на экономику, приводя к убыткам, которые оцениваются в 979 миллиардов долларов ежегодно. Пример из видео: потеря слуха затрагивает продуктивность людей, что приводит к значительным экономическим потерям.

💡Профилактика

Профилактика — это меры, направленные на предотвращение потери слуха до того, как она станет необратимой. В видео подчеркивается важность профилактических мер, таких как использование наушников с шумоподавлением и снижение громкости музыки. Пример из видео: автор рекомендует активное шумоподавление как одну из стратегий профилактики потери слуха.

💡Тест слуха

Тест слуха — это процедура, которая используется для измерения способности человека слышать различные частоты звуков при разных уровнях громкости. В видео несколько раз упоминается тестирование слуха как важный инструмент для ранней диагностики потери слуха. Пример из видео: автор предлагает пройти тест слуха, чтобы определить, насколько ваше восприятие звуков соответствует вашему возрасту.

Highlights

Apple introduces three major health features for AirPods Pro 2 focusing on hearing loss prevention.

Apple's commissioned study with the University of Michigan highlights the growing concern around hearing loss.

The World Health Organization report emphasizes hearing loss as a global issue, with 430 million people suffering from moderate or severe hearing loss.

Hearing tests measure your threshold for different frequencies and help identify mild, moderate, or severe hearing loss.

Mild hearing loss is already widespread, affecting around 1.15 billion people globally.

Prolonged exposure to loud noise can cause permanent damage to hair cells in the cochlea, leading to irreversible hearing loss.

Decibel levels are logarithmic, meaning small increases in decibels represent significant jumps in sound intensity.

Loud noise from machinery or recreational music through headphones contributes significantly to hearing loss.

Apple's environmental noise notifications are designed to help users monitor and manage exposure to potentially harmful sound levels.

Tinnitus, a ringing in the ears, often occurs after prolonged exposure to loud noise, signaling possible hearing damage.

Governments should invest in healthcare facilities for audiometric evaluations to prevent hearing loss, especially in low-income countries.

Workplaces should adopt policies to limit exposure to noise above 85 dB and provide hearing protection.

Companies benefit economically from investing in hearing protection and hearing loss prevention measures.

Individuals can reduce the risk of hearing loss by using noise-canceling headphones and lowering music volume.

The economic impact of hearing loss is significant, estimated at $979 billion globally, underscoring the need for preventive action.

Transcripts

play00:04

So I was just finishing up

play00:06

watching this Apple event

play00:08

that happened a few hours ago.

play00:09

Welcome to Apple part.

play00:11

And well, there was a

play00:11

segment in this wherein

play00:12

there was a massive

play00:13

emphasis on hearing loss

play00:15

and preventive measures for it.

play00:17

Today, we're introducing

play00:18

three major health features

play00:20

for AirPods Pro 2.

play00:21

So there was also the

play00:22

mention of this study

play00:23

that apparently Apple commissioned

play00:25

along with the University of Michigan.

play00:27

And also this report by

play00:28

the World Health Organization

play00:29

as to how hearing loss is

play00:30

perhaps a silent epidemic

play00:32

that we don't really know about.

play00:33

And I think I have a guess

play00:34

as to who the culprit may be.

play00:37

(upbeat music)

play00:39

Thing is I use this for

play00:41

several hours in a day

play00:42

and I get those noise notifications

play00:44

much more than I would like.

play00:46

Now Apple introduced

play00:47

this notification system

play00:49

a few years ago.

play00:50

I was much younger then.

play00:51

So is all of this presentation,

play00:52

all of the hearing

play00:53

things that they talked about,

play00:54

is it really very serious?

play00:56

So in this video, I'm

play00:57

actually gonna try and figure out

play00:58

whether any of this

play00:59

actually really matters.

play01:01

Well, spoiler alert,

play01:01

it really does matter.

play01:03

That's a 1.1 billion with a B.

play01:05

I'm also going to figure out

play01:06

what causes hearing impairment

play01:08

(static)

play01:10

and what impact does it have,

play01:12

not just on an

play01:13

individual, but also on our society.

play01:15

And ultimately we're also gonna discuss

play01:16

what can we and the governments do

play01:18

to prevent this from

play01:19

becoming the next epidemic.

play01:21

Stay tuned and let's figure this out.

play01:23

(upbeat music)

play01:33

(people chattering)

play01:42

So let's start with the big document

play01:43

which is going to form

play01:44

the backbone of this video.

play01:46

This report by the World Health

play01:47

Organization on Hearing

play01:49

clearly states that hearing loss

play01:51

is quite a prevalent problem.

play01:52

It says that across the globe,

play01:54

nearly 430 million people

play01:56

suffer from either moderate

play01:58

or higher grade hearing loss.

play01:59

Now what really constitutes a moderate

play02:01

or a higher grade hearing loss?

play02:03

Well, for that, we need to understand

play02:05

how a hearing test is done.

play02:07

For the study, the hearing

play02:08

test was done as follows.

play02:09

You are supposed to

play02:10

hear a range of frequencies

play02:12

going from low to high

play02:14

at different volumes,

play02:16

from very quiet

play02:17

volumes to very loud volumes.

play02:19

And for each frequency

play02:20

tone that you listen to,

play02:21

which will probably

play02:22

sound something like this.

play02:24

(low-pitched tone)

play02:33

Each of that, you need to determine

play02:35

what's the lowest volume

play02:36

that you can hear that.

play02:37

So let's say this frequency of 250 hertz,

play02:40

you can hear it at about 20 dB,

play02:42

and then you do that again

play02:43

for the rest of the frequencies

play02:45

and you create a plot for yourself.

play02:47

So this is what is called an audiogram.

play02:50

And through this, you can determine

play02:51

what is your hearing threshold.

play02:53

And by determining what

play02:54

your hearing threshold is,

play02:55

you can then really understand

play02:57

what levels of hearing

play02:59

loss are you suffering from.

play03:00

If your threshold was about 20 dB,

play03:02

you have pretty normal hearing.

play03:04

But for moderate and

play03:05

higher grades of hearing,

play03:06

your threshold is much higher than 20 dB.

play03:10

This means that the test

play03:10

frequencies that you listen to

play03:12

were audible to you at

play03:13

a much higher loudness

play03:14

than somebody with a normal hearing.

play03:16

And as you can see, this

play03:17

does have quite a big impact

play03:19

on your daily life.

play03:20

But for me, what

play03:21

actually is already an epidemic

play03:23

is perhaps the mild hearing loss.

play03:25

Thing about moderate

play03:26

and severe hearing losses

play03:28

is the fact that it was once a very mild

play03:30

case of hearing loss.

play03:31

And you wanna know how

play03:32

many people actually have

play03:34

a mild case of hearing loss?

play03:35

Nearly a billion people.

play03:37

Now this is what the actual epidemic is.

play03:40

1.15 billion people have

play03:42

a mild grade hearing loss.

play03:43

So if people keep continue

play03:44

doing what they are doing,

play03:46

moderate and even severe hearing losses

play03:48

might not be that distant away.

play03:50

So coming back to this, why

play03:52

does this actually happen?

play03:53

Why do some people

play03:54

hear a certain frequency

play03:55

at a certain level,

play03:56

and while the others hear

play03:57

it at a certain other level?

play03:58

Well, to answer that, we

play03:59

need to first understand

play04:00

how loud noises affect our ears.

play04:03

And for that, I tried to

play04:04

read this very technical paper,

play04:07

and this thing had very few images

play04:09

that I can really look at.

play04:11

So we might have to figure something out

play04:13

to make you understand how

play04:14

our ears work with loudness.

play04:15

This is what the ear

play04:16

looks like, by the way.

play04:18

Sound waves enter from here, obviously.

play04:20

I really want to highlight this part,

play04:22

which is called the cochlear, cochlear.

play04:24

Call it the coochie for the first five

play04:25

minutes, by the way.

play04:26

And within this lies the receptors

play04:28

which send the signals to the brain

play04:30

that just you're hearing something.

play04:32

Now, those receptors

play04:32

are called hair cells,

play04:34

and they look somewhat like this,

play04:36

more specifically, like

play04:37

the bristles on this brush.

play04:39

And this is, let's say, a sound wave.

play04:41

So when a sound wave comes in,

play04:43

they indirectly move these bristles,

play04:45

thereby indicating to the brain

play04:46

that, hey, there's something that you

play04:48

should be listening to.

play04:49

As you can see, these bristles

play04:51

do regain their position back

play04:52

after the disturbance,

play04:53

but when you're exposed to loud sounds

play04:55

for a longer period of time,

play04:57

these bristles start to

play04:59

look something like this.

play05:02

Consistently loud noise

play05:04

bends these out of proportion,

play05:05

and it's a permanent bend.

play05:06

Some of these are even completely

play05:08

disconnected, by the way.

play05:09

And this is the reason why

play05:10

hearing loss damage is kind of permanent.

play05:12

Now, one of the few

play05:13

things that I was actually able

play05:14

to understand through this paper

play05:15

was the fact that this

play05:16

damage is irreversible.

play05:18

So prevention is the way to go with this.

play05:21

And also the fact that decibels

play05:22

are a very tricky unit of measurement.

play05:24

So let's say if you thought that going

play05:25

from 90 to 100 decibels

play05:27

was just a little bit of an increase,

play05:29

well, that is not the case,

play05:31

because decibels don't

play05:32

really work linearly.

play05:33

And nobody mentioned

play05:35

that this is not a PNG.

play05:36

This is what we have, okay?

play05:37

Going from 90 decibels to 100 decibels

play05:40

is not a small jump.

play05:43

It's insane how decibels work.

play05:44

It's not insane, it's just math.

play05:46

So let's say when

play05:46

you're doing the hearing test

play05:47

and you jump from 70 to 80,

play05:50

it's not that small of a jump.

play05:52

It's a big, big jump,

play05:52

and the loudness is

play05:53

much, much more intense.

play05:55

I mean, just look at how

play05:56

much the difference there is

play05:57

between 100 decibels

play05:58

and 120 decibels, my God.

play06:00

I sometimes get

play06:01

notifications that my environment

play06:02

is at 100 and something decibels.

play06:04

Now, I'm not gonna suffer by myself.

play06:06

I'm going to give you guys

play06:07

a reality check, I swear.

play06:09

Be prepared for your first hearing test.

play06:11

I said first, there's

play06:12

gonna be many in this video.

play06:13

So I'm sure you've been

play06:14

in this situation before.

play06:15

You're trying to have a

play06:16

conversation with your friend

play06:17

who's on the other side of the sofa,

play06:18

which is about a meter and a half away.

play06:21

Now, he works in a

play06:21

place where he's exposed

play06:22

to a lot of loud machinery.

play06:24

I have a doubt that he

play06:25

might be in a spectrum

play06:26

of moderate to severe hearing loss.

play06:29

And we can check that out,

play06:30

but just having a

play06:31

conversation 1.5 meters away.

play06:33

If he's able to hear

play06:34

me, his hearing is fine.

play06:36

If he doesn't, it might be a problem.

play06:40

So do you know that we have

play06:41

a social media agency now?

play06:43

Yeah, and it really doesn't matter

play06:45

how many followers you have.

play06:46

If you have any social media content,

play06:48

which you feel is something

play06:49

that you've been thinking about

play06:50

for a long time, or any project, really,

play06:53

that you can't really

play06:53

get done by yourself,

play06:55

we can help you out with that.

play06:57

We can help you with YouTube,

play06:58

we can help you with podcasts,

play06:59

we can help you with Instagram reels.

play07:01

Anything really that you

play07:02

feel is worthy of social media.

play07:05

Of course, if you'd like to get involved,

play07:07

scan this QR code and help us help you.

play07:11

Did you hear any of that?

play07:12

(speaking in foreign language)

play07:16

So what's the reason that so many people

play07:18

actually have a mild

play07:18

grade of hearing loss?

play07:20

Now, if you take away the

play07:20

more biological side of things,

play07:22

which is infections and diseases

play07:24

that lead to hearing losses,

play07:26

there are two main

play07:27

reasons why people have this.

play07:29

First is loud noise

play07:30

exposure due to occupation.

play07:33

(loud noise)

play07:39

Second is the recreational

play07:41

music that you listen to.

play07:42

You know, when you're

play07:42

listening to your music

play07:43

on your headphones, and it's so loud

play07:45

that everybody else can

play07:46

listen to your music as well?

play07:47

Yeah, I'm talking about

play07:48

that level of noise exposure.

play07:50

Also, if you're one of those people

play07:52

who likes to put those cotton bud things

play07:54

inside of your ear, you

play07:55

are not doing anything.

play07:56

In fact, you are increasing

play07:57

your chances of hearing loss

play07:59

because you're irritating your eardrum

play08:01

and also the case of having an infection.

play08:03

So if you want to get your ears clean,

play08:05

get a professional to do that.

play08:06

Don't do that by yourself.

play08:07

Please stop.

play08:08

I don't think you can hear me.

play08:09

Please stop doing that.

play08:10

Do please.

play08:10

Please stop doing that.

play08:12

F*$K You in ASL

play08:18

So I would like to believe

play08:19

that you who are watching this

play08:21

would at least now care

play08:22

about your personal journey

play08:24

of hair loss.

play08:24

Not hair loss. Hearing loss.

play08:26

I'm not trying to make this funny,

play08:28

but why should anybody else care?

play08:30

Why should the government care?

play08:31

Why should companies care?

play08:32

Why should anybody,

play08:33

apart from you, really care?

play08:35

Well, because people matter,

play08:36

and if people suffer from hearing loss,

play08:38

it'll severely impact their way of life.

play08:40

And that would lead

play08:40

to the biggest problem

play08:42

that anybody ever fears of,

play08:43

which is the economic

play08:44

impact of hearing loss.

play08:46

I don't think it's the biggest thing

play08:48

that anybody ever fears.

play08:49

That might be nuclear

play08:50

catastrophe or something.

play08:51

The thing is the

play08:51

economic impact of hearing loss

play08:53

is quite significant.

play08:54

In this paper, for example,

play08:55

it estimates how much hearing loss really

play08:57

impacts the economy,

play08:59

and it turns out to be

play09:00

somewhere a very small number

play09:02

of around $979 billion.

play09:06

$979 billion.

play09:08

This is so much more bigger

play09:09

than what I anticipated it to be.

play09:11

I guess this is why it makes sense

play09:13

that Apple has invested so much.

play09:16

In fact, even conducted a study

play09:18

with the University of Michigan

play09:20

towards understanding

play09:21

as to why hearing loss

play09:22

can be such a big problem.

play09:25

So clearly, all of

play09:26

these fancy notifications

play09:28

are not just our marketing gimmick.

play09:30

Apple directly benefits from the fact

play09:32

that people have sound hearing,

play09:34

and they have

play09:34

obviously invested a little bit

play09:37

into figuring out how.

play09:38

Well, now it's time for

play09:39

our very own hearing research

play09:40

and the second test for

play09:41

our hearing loss program.

play09:43

I should not be calling it that, my God.

play09:44

I'm sure you've been in

play09:45

a place like this before,

play09:46

with lots of construction,

play09:48

lots of loud noises,

play09:49

and if you stay here for

play09:50

more than a few minutes

play09:51

without any protection for your hearing,

play09:53

then you move to a place like this,

play09:54

which is much more

play09:56

quieter, much more remote.

play09:58

You can sometimes hear a

play09:59

bit of a ringing in your ear.

play10:01

This phenomena is called tinnitus,

play10:03

and it's just your

play10:04

brain playing games on you

play10:05

because your ear is not

play10:06

functioning as it's supposed to.

play10:08

So if you feel like there's a constant

play10:09

ringing in your ears

play10:11

and it's happening more

play10:12

frequently and for longer times,

play10:14

perhaps it's time to see a professional.

play10:15

And the question is, what can we do

play10:17

to prevent this from becoming a

play10:19

widespread epidemic?

play10:20

Well, we can take a look at it from a

play10:22

government perspective,

play10:23

from a workplace perspective,

play10:24

and from a personal perspective.

play10:25

Let's first start with

play10:26

the government perspective.

play10:27

One of the biggest challenges

play10:29

that any government

play10:29

really has in this sector

play10:31

is the fact that there's a

play10:32

severe lack of professionals,

play10:33

especially in the

play10:34

countries which are rather poor

play10:36

in comparison to its West counterparts.

play10:38

So one of the first things that

play10:39

government should really do

play10:41

is provide a better healthcare facility

play10:44

for audiometric evaluations

play10:45

because the more

play10:46

professionals that come in,

play10:47

the more awareness there will be

play10:48

towards the silent epidemic.

play10:50

They can also help in

play10:51

creating policies in workplaces

play10:53

that can help monitor things better

play10:54

and prevent hearing loss altogether.

play10:57

So talking about

play10:58

workplaces, what can they do?

play11:00

Well, let's say they can

play11:01

put a few policies in place

play11:03

with help of the professional.

play11:04

For example, it is stated that at 85 dB,

play11:08

then the work shifts

play11:09

should only be eight hours long.

play11:11

If the noise level is higher, the work

play11:13

shifts need to reduce.

play11:15

Similarly, there can be more emphasis on

play11:17

hearing surveillance

play11:18

so that there are more frequent

play11:20

regular audiometric evaluations.

play11:22

In fact, if it's a

play11:23

daily exposure measurement,

play11:25

that can be one of the

play11:26

most safe at practices ever.

play11:27

There should be proper

play11:27

use of hearing protectors.

play11:29

And obviously, if possible,

play11:31

there should be lack of use of equipment

play11:33

which create a lot of noise.

play11:35

But these are quite the

play11:37

obvious points in this case.

play11:39

What really companies should think about

play11:40

is the fact of how much can

play11:42

they really benefit from this.

play11:43

Now, I did talk about

play11:44

how the general economy

play11:45

will be affected with hearing loss,

play11:47

but I would also like to talk about

play11:48

how the companies would benefit from this

play11:50

by investing in hearing

play11:52

loss measurements directly.

play11:53

You can clearly see how

play11:55

much you get in return

play11:56

for every dollar that you've invested

play11:57

in hearing loss measurements.

play11:59

And these are marked by two

play12:00

different set of predictions,

play12:01

one which is more progressive

play12:03

and one which is a bit more ambitious.

play12:05

So you can actually make money

play12:07

by investing in hearing loss measures,

play12:08

which is what companies do, right?

play12:10

Now it is time to talk about

play12:11

what we as individuals can do

play12:13

to prolong our hearing capabilities.

play12:16

And the answer for it...

play12:19

(drum roll)

play12:21

You should be wearing your headphones.

play12:23

But don't just any

play12:24

headphones, noise canceling ones.

play12:26

Let me explain.

play12:27

So I hope you remember

play12:28

this graph from earlier.

play12:29

This is what we described as a sound wave

play12:31

and we know already the

play12:32

damage that it can do.

play12:34

So the reason that these headphones

play12:35

can be an effective

play12:36

tool for sounds like these

play12:38

is because they have something called

play12:40

active noise cancelling.

play12:41

What it means is that

play12:42

for every sound wave

play12:43

that is generated,

play12:45

the active noise cancelling headphones

play12:46

generate a wave of its own,

play12:48

which is exactly the

play12:50

opposite of the sound wave.

play12:51

So what does that mean?

play12:53

Destructive interference and no sound,

play12:55

no waves entering your ears.

play12:57

What I've started doing recently

play12:58

is that I've started using

play12:59

more of the noise cancellation

play13:01

and just lowering the volume of the music

play13:03

that I'm listening to.

play13:03

It kind of then puts

play13:04

me into my own waggle,

play13:05

so I don't really understand what's

play13:06

really happening outside,

play13:07

which is good for an introvert like me.

play13:09

And my notifications have

play13:11

dropped by significantly

play13:12

in the past few months.

play13:13

And if you see September,

play13:15

you'll see that I've only had one

play13:16

notification until now.

play13:17

At least now I feel a

play13:18

little bit better about myself.

play13:20

Perhaps wearing these

play13:20

bulky ass headphones

play13:21

with noise cancelling in them

play13:22

might just salvage my

play13:23

hearing in the long run.

play13:25

So for the last time,

play13:26

I would just like to

play13:27

emphasize on the fact that

play13:28

hearing is a very

play13:29

fundamental sensory function.

play13:31

It is important for critical

play13:33

daily human functionalities

play13:35

and any degree of loss that you will have

play13:37

will have monumental

play13:38

impacts on your daily life.

play13:40

And like I have mentioned this

play13:41

a thousand times before in this video,

play13:44

prevention is the only

play13:44

way, at least for now,

play13:46

to take care of your ears

play13:47

because of the fact that there's gonna be

play13:48

another hearing test

play13:49

going to happen right now.

play13:50

Okay guys, we're nearly

play13:51

at the end of the video.

play13:54

That was quite loud.

play13:55

So before we run the final test,

play13:57

and we'll just like to believe that

play13:58

if you like this video enough,

play13:59

please do like and share.

play14:01

I can't emphasize how much a

play14:02

like and share helps us out

play14:04

because when the YouTube gods see that

play14:06

this is being shared and liked by people,

play14:08

they tend to help us reach out to

play14:10

a much larger audience

play14:11

than what you already have.

play14:12

And that's the biggest struggle that I

play14:14

have at this moment.

play14:15

I don't know how to get more people

play14:17

to care for content like this.

play14:18

In any case, I will

play14:19

be here in a few days,

play14:20

but if you can help me out,

play14:21

that'll be very much appreciated.

play14:23

So now let's do the final hearing test.

play14:24

You're gonna listen

play14:25

to a set of frequencies

play14:27

and you have to just

play14:27

determine which frequency

play14:29

was the last one that was audible to you.

play14:31

And just for reference, you'll also see

play14:32

at what age generally

play14:34

people are able to hear

play14:35

that frequency.

play14:36

So this can help you

play14:36

assess whether your hearing

play14:38

is suitable for your age

play14:39

or whether you should be taking

play14:40

corrective measures.

play14:41

So I'm gonna go and get some coffee

play14:43

and you should perhaps try this test out.

play14:46

Thank you again for watching

play14:47

and I'll see you in a few days.
