does life have a soundtrack
from our first moments we are
bombarded with sound wherever we are
not a moment goes by that we
don't hear something
much
like a sunset over the
sea without the lapping of the waves
an opera without great air
or a birthday without the strict song
how much do noises and sounds
influence
us we all hear the same thing
and if one is such as this one
reaches us we all perceive it the
same way
[Music]
what do we hear when a sound is
waiting for us
and what impact does it have on us
[Music]
our hearing is solicited by very
many people 24 hours a day
[Music]
[Music ]
one of the most
cnce
louis of the human being is actually
able to perceive minute
variations
our ear can differentiate up to
20 signals per second and identified
four hundred thousand are an element
is essential for us to achieve this
is the 'era
the guen was playing
[Music]
well if there is no air to vibrate
everything we hear is therefore
neon
but then does that mean that
the noises of battle in all
star wars movies are ultimately just lies
a
space no
so it is the air that allows us
to hear and it is thanks to its
atmosphere that our planet has been able to
develop such a complex sound design
this season of smartphone made
stay at two customers
[Music]
and on the surface of the earth
the first thing that makes noise
is of course
life
starting with animals every
bird every mammal
all make noise down to the smallest
spiders fish reptiles
but how do we manage to
differentiate these sounds from what tools
our ear and the team and
[Music]
the sound waves first strike the
eardrum a thin membrane located at
the end of the external auditory canal
this converts the sound waves into
vibrations and transmits them to the
middle ear more precisely at 3o that the
hammer and the anvil and sort
them they are a bit the amplifiers of our sense
of hearing and they transmit the
vibrations to our inner ear
we there are the semi-circular canoes
and the cochlea the size of a
pea it is made up of liquids and
very fine hair cells which in
turn convert the
vibrations into an electrical signal which is
transmitted to the brain by the auditory nerve
c' is where our consciousness takes over
[Music]
all the noises and sounds that
reach us we perceive that a
third of them
as if our brain was doing the
hockey cry imagine a little you arrive at
a party and you are overwhelmed by the
noise conversation music glasses
clinking
all at the same time a carpet of sound
dances and impenetrable and then in the middle
of this chaos a word or maybe a
sentence all stands out
how is it possible
a young man
with a
physique to process
our brain constantly seeks
explanations for practically everything
we perceive the noises and sounds
that reach our ear are therefore
above all an interpretation of the brain
and the bicross
action
our brain is constantly playing
guessing games to make sense of each
noise each are they deploy for
this an extraordinary
computing power and there is a good reason for this
in the past it was absolutely vital to
decode the are quickly and
efficiently
[Music]
one is a civil servant
being able to react to a threat
this is one of the reasons why
we perceive noises and sounds
with as much precision animals
also sometimes do it much better than
us
pigeons are able to hear infrasound
cats and bats ultrasound
[Music]
but something must have happened
between the tiger and the cocktail party
because if we manage to isolate a sentence
in the hubbub
the cat is not capable of it
the human and the cat perceive the tiger
in the same way at the center of the
cerebral circuit of fear the amygdala goes into
threat mode we flee
during the cocktail party it's
different here it's mainly the brain
that suddenly comes into action all the
memories of the
experiences and expectations accumulated
during our life play a role

and as we live and work with
others if possible in good agreement
it is important to be sensitive to the
tiniest shades of voice in order to be
able to assess a situation
and your hostile or friendly towards us.
it of danger or
benevolence is our interlocutor
sad frightened angry or in love
[Music]
and then there are also sounds like
these that can influence us even
bring us strength
[Music]
we are not the only to be
influenced by music
star of youtube the lowball cockatoo
is the living proof
of this researchers from harvard and
tufts university have
recently discovered that it is even able to
recognize the measure
[Music]
and
in
addition to the rhythm the measurement
also exert a great influence on our
things that no one has better demonstrated
than him
ludwig van beethoven
some of these piano sonatas
would indicate that his heart was not beating
in a regular rhythm
and then there is the percussive rhythm of
symphony number 5 which earned him the name
of symphony of destiny
according to ilan choo some pieces of
music would even identify
certain heart rhythm disorders
or even treat them

[Music]
classic connected to precise wi music
ah yes yes
it's almost as if this music
was telling us a story and that our
intuition was telling us that something
was wrong with the story
[Music]
where
you too are waiting for the end
[Music]
ok
as soon as we perceive sounds our
brain forces not only to
find a meaning to them but in addition it creates
expectations it is a question of telling
the story to the end
[Music]
all the sounds that passes through our ears
to reach our brain arouses
expectations and triggers emotions and
it is in this way conditioned by
our thoughts and our feelings that they
can also exert an action on
our body
yes to look into you
and music
tab rhythm of
families of might be
and that p
and both
but how come it how can the
same music the same sounds and the same
noises have such a
different impact on each of us for example
that arouses this noise in you want
style of marble where does it give you
joy the effects of smr on our
brain have been known for a long time on
youtube long before science
looked into the question
smr videos of tasting macaroons or
scraping leather bets on the eroticism of
sound for some it is this noise which is
relaxing for others it will be rather
this one
[Music]
it's a safe bet that among the
millions of people who watch
online programs by the artist bob
ross to learn to paint many
are there just because the sounds
soothe them
so there are sounds that have a
calming action on some of
us
unfortunately there are also
more and more that are frankly
annoying
why are people disturbed by
a noise rather than another
[Music]
expert
[Music]
ès because
they
take for example the soundscape
of a city some people are crazy about it
while others love it
some even revel in the noise of a
passing metro
but if sounds and noises can influence
our influences so much and
could it not make us manipulable and
if it could be used to make us
buy certain products

you can't you
today many noises which
surround us do not correspond to
reality they were imagined to
produce a certain effect

while they remained authentic

surely not those of the program you
are watching
this
[Music]
in fine
it's true we watch a film but we
also listen to them and you what
influences you the most the images or
the sounds what will you remember
from this program
focus
under the surface hides a whole
sound universe a universe of which we unfortunately we are
too rarely aware
we often say damn

being friendly
one thing is certain the world is not
that before our eyes it is also in our
ears and since we do not
all hear the same way it would be worth
perhaps it is worth determining which
noises and sounds are the most
likely to excite us, to
appease us or to enrich us
for that, let's try to listen a
little more
