00:00:02
muskin channel and today we will have
00:00:03
a video dedicated to noise vibration insulation of
00:00:06
doors thousand of their audio preparation from the point
00:00:08
of view of car audio and of course from the point
00:00:10
of view of your comfort,
00:00:11
after all, it costs two tasks in terms of
00:00:14
vibration isolation, this will reduce the noise as much as possible
00:00:16
and which from the outside spread
00:00:18
inside the car, of course, they not only
00:00:20
come from the doors, they also come from the arches and
00:00:22
many other places, but today we will consider
00:00:23
only the doors and, accordingly, the second
00:00:25
point is the audio preparation of the door from the point of
00:00:28
view of the speaker, so for convenience, we
00:00:30
will draw a schematic diagram of our door, that is,
00:00:34
it consists from the outer part of the door there are
00:00:36
technological holes and the casing itself
00:00:39
somewhere here we have the speaker itself installed,
00:00:41
that is, this is the part on which everyone
00:00:43
usually knocks and checks the quality of
00:00:45
the sound insulation, but in fact this is not exactly
00:00:47
how you need to approach it,
00:00:50
first from the point of view of the audio system that
00:00:52
we get it as we understand it and we
00:00:54
attach it to this wall,
00:00:56
so the maximum rigidity
00:00:58
should be precisely released, that is, in
00:00:59
principle, the task from the point of view of sound is
00:01:01
to work with this wall,
00:01:05
so to speak, what you put on the back of the speaker does not have a
00:01:06
particularly strong effect, but now about not
00:01:08
We’ll tell you in more detail because what we
00:01:10
have is that the speaker essentially works
00:01:12
in a milled design, that is, we
00:01:15
have a speaker, it propagates waves,
00:01:17
respectively, it enters us both forward
00:01:19
and backward, it propagates both on
00:01:20
the front and rear parts,
00:01:23
ideally if a person is allowed
00:01:25
is located here, he should never
00:01:27
hear this part of the wave that we
00:01:29
have formed on the business side, that is,
00:01:31
we should have this part of
00:01:33
the door completely isolated here,
00:01:34
imagine that you are drawing, roughly
00:01:36
speaking, water into the inside of the door and the water does
00:01:38
not flow out anywhere, all these cracks all
00:01:40
technological holes do not
00:01:41
have to be sealed,
00:01:42
they can be glued as vibration insulation, but
00:01:45
ideally, of course, with something more rigid, that
00:01:47
is, there are special sheets of aluminum,
00:01:48
someone can seal it with, say, plywood, that
00:01:51
is, 1 the essence is the next one, which is what we have
00:01:53
if we started talking about that part
00:01:55
where the speaker itself is attached,
00:01:56
that is, we will seal the technological
00:01:58
holes, it can be any hard
00:02:01
material, even you can
00:02:02
make it with fiberglass, all these holes can be
00:02:04
sealed, you can use aluminum,
00:02:06
let’s do some things that are not
00:02:08
necessary, of course, for example, I’ll show
00:02:10
you here there is some kind of
00:02:11
technological hole in the door
00:02:13
can be made by strengthening it with an
00:02:15
aluminum plate, for example, either you do
00:02:17
this or then, for example, like this, and then
00:02:19
put a sheet on top and vibration insulation,
00:02:22
let’s say 3 millimeters thicker, it does
00:02:24
n’t make much sense to use it, because
00:02:25
in any case, somewhere else
00:02:27
we have a doll that holds the skins and so that they did
00:02:29
n’t give too much thickness 3
00:02:32
millimeters here, in principle, it’s enough,
00:02:33
so, in principle, the maximum work
00:02:36
we do is just on this wall, mine and
00:02:39
we’ll glue it, you’ll make, roughly speaking, the
00:02:41
Japanese stiffening ribs with vibration isolation glue,
00:02:43
if we have enough space, we can
00:02:45
even put another sheet on top so that this
00:02:47
wall is as rigid as
00:02:48
possible, so to speak, well
00:02:51
sealed so that there is no rattling on it,
00:02:53
and all the vibrations that will be created by
00:02:55
our speaker, this is especially true
00:02:57
for midbass, that is, if you put
00:02:59
something very low playing,
00:03:00
let’s say there is some kind of snare like Ural
00:03:03
velvet or some other speakers there are
00:03:05
up to 100 and 200. 3 twenty, which has a
00:03:07
very powerful magnetic system, it is
00:03:09
designed to play frequencies there, let’s say
00:03:11
even from 40 to 400 hertz,
00:03:13
respectively, the resonance of our door
00:03:15
should be less than 40 hertz, in this
00:03:18
case
00:03:19
we will not hear any ghosts of such resonances in this house,
00:03:21
in this part everything is clear
00:03:23
there is no point in gluing sound insulation on it,
00:03:25
because after all, the noise we have
00:03:27
is on this side, so he
00:03:29
glued the sound insulation only on the door trim,
00:03:31
so in principle we cover it with vibrations and
00:03:33
that’s all we have regarding the part
00:03:37
that is outside on which everything is normal
00:03:39
tap with your finger and check the vibration
00:03:41
isolation of the sound insulation of your car,
00:03:43
if you still connect your finger from and
00:03:46
the sound, so to speak, is completely deaf, this does
00:03:48
not mean at all that your car has poor
00:03:50
vibration isolation, that is, for example, we are already
00:03:52
in this form before we consider our door
00:03:56
that our doors are in In any case, we most
00:03:58
likely have some kind of
00:04:00
stiffening ribs, standard ribs, they are there like the
00:04:02
right glue on pieces, even in
00:04:04
some cars there is a business class
00:04:05
camera and similar things, actually
00:04:07
inside
00:04:08
you will be surprised when you take this whole thing
00:04:09
apart, there is nothing there in fact, no, that
00:04:11
is, this level of professional
00:04:13
sound insulation is
00:04:14
not done anywhere at the factory, and therefore all
00:04:16
these configurations that are
00:04:17
imposed on you by dealer managers
00:04:20
directly at the car dealer, so let’s
00:04:23
say it’s all money, skills, it’s not
00:04:24
easy to glue
00:04:25
three pieces of it with a lot of money for it and
00:04:27
you’ll get the result is just 0 now we
00:04:29
will tell you how to do it much better more
00:04:31
efficiently and at the same time the costs will
00:04:33
also be minimal because we have inside
00:04:35
the doors the first thing we do is the first stage
00:04:37
yes we disassemble we remove the casing I thought
00:04:40
there are a lot of viruses on youtube if you do
00:04:42
it yourself we looked at your
00:04:45
car's trim was removed carefully, not a word
00:04:46
about the doll in some places, of course you
00:04:49
have to remove the window regulator itself, in
00:04:50
general the essence is clear, we need access to the
00:04:52
metal of the door directly, we
00:04:54
completely degrease it, we take the usual one
00:04:56
in front of you, for example, and wipe everything dry until the
00:04:59
entire surface is washed,
00:05:00
it is very important that vibration isolation it didn’t
00:05:02
come off and there were no problems, it’s
00:05:04
washed out, everything is completely dried,
00:05:06
here we’ll cheat a little
00:05:09
inside the door, there’s no point in gluing very
00:05:11
thick material, they usually weigh
00:05:13
too much, they’re bent, there’s your
00:05:15
cost, your weight, it’s simply not
00:05:17
needed, that is, in any case our task is
00:05:19
simply to remove unnecessary vibrations, namely the
00:05:20
ghosts of the metal itself, respectively, the
00:05:23
metal of the car is thin, it can rattle
00:05:24
ringing. Our task is to remove everything with you.
00:05:26
What we do is we buy, in
00:05:27
principle, the usual 3 millimeter insulation,
00:05:29
for example, for example, up to the comfort of the O’s C
00:05:32
grade, the usual one can, of course, there will be a series
00:05:34
there will be a little the result is cooler, that
00:05:36
is, the sound absorption coefficient here
00:05:37
already depends on the budget, let’s say, we are
00:05:40
guided by materials that are
00:05:42
more expensive, where the thickness in microns of the
00:05:44
aluminum itself is greater, and for example,
00:05:46
either the mastic layer itself is another of the
00:05:48
budget ones, this is the aura of this series, in
00:05:51
principle you can also use it, but we are
00:05:52
cunningly empty in what do we do,
00:05:55
we buy this sheet of vibration insulation
00:05:56
for the door, it takes us
00:05:59
about two pieces for an average
00:06:01
door, if they don’t buy a car from you,
00:06:03
we cut
00:06:06
the vibration insulation itself into 10 centimeter pieces, approximately wide, and
00:06:08
start with glue from the bottom of the door, that is, we
00:06:10
take the first part
00:06:12
we warm up the interior to 20 degrees,
00:06:14
respectively, so that all this is in
00:06:16
warm temperatures,
00:06:17
we glue the lower part 10 centimeters
00:06:19
3 millimeters of the second sheet and glue it
00:06:21
overlapping the first one and a half to two centimeters,
00:06:24
that is, we get a place specifically
00:06:26
this place in which vibration isolation is 6
00:06:29
millimeters 803 and applied three more, this
00:06:32
turns out to be a stiffening rib due to the fact
00:06:34
that it is thicker, that is, we all
00:06:36
know that
00:06:37
in any on the hood on the doors in the car
00:06:40
for a reason, these are all the same to give
00:06:41
design lines, they take not only the
00:06:43
visual effect to create but
00:06:45
nevertheless the rigidity of the metal because it is possible to
00:06:47
make a car out of thinner
00:06:48
metal using the stiffening ribs, we
00:06:51
get the maximum, let’s say
00:06:53
the rigidity of the structure in any case,
00:06:55
take an aluminum can from what kind of
00:06:56
injections, try and death just
00:06:58
inside bends easily
00:06:59
on the stiffening ribs, the narrow principle is
00:07:01
also unrealistic here, therefore, we take
00:07:03
2 centimeters ten to fifteen
00:07:04
depending on the door, it turns out
00:07:06
that there are two there 3 4th place is about
00:07:08
here already as you will get here in this
00:07:11
here in this place we have three
00:07:13
stiffeners, they are all 6 millimeters thick
00:07:15
and despite that that we glued with material 3
00:07:19
millimeters in some places we have 6
00:07:21
plus they also work like a fish of rigidity,
00:07:23
respectively, the rigidity of
00:07:25
the structures itself increases simply by a multiple,
00:07:27
that is, your costs are minimal and
00:07:29
because you glued only a trinity
00:07:31
but due to this and these due to these
00:07:33
ribs are just on the back side of the door, the
00:07:34
maximum rigidity of the structure is all
00:07:37
about this, that is, why it is done from
00:07:39
the bottom, they are glued on top so that yours is
00:07:42
located on top, that is, there is
00:07:44
water inside the door in any case, the
00:07:46
water will simply dig and flow into the
00:07:48
door if you will glue
00:07:50
the sheet on the contrary, respectively, from the bottom so that
00:07:53
you overlap, you will make an overlap here, here you will be
00:07:54
one and a half centimeters, then water
00:07:55
can still get in, it’s not entirely convenient,
00:07:57
so glue from the bottom so that the water
00:08:00
flows calmly, the water will absolutely always be in the form
00:08:01
because there are lifts nearby,
00:08:04
open the door, close the door,
00:08:05
the seal in the rubber bands on the window lifter,
00:08:08
as a rule, they
00:08:10
pass through the legs in any case, so moisture
00:08:12
inside the door is normal,
00:08:14
condensation will form there in any case, so
00:08:16
all materials are made of aluminum so that there
00:08:18
is no oxidation, so seal the
00:08:21
bottom of the door in any door, as you
00:08:23
know, there are special holes for
00:08:24
draining the water,
00:08:25
they are in any car; under
00:08:27
no circumstances should you seal them so that moisture can easily
00:08:29
come out of the car; you open the door,
00:08:31
a couple of drops fall out, and at the same time,
00:08:33
everything is the same as an option for
00:08:35
improving the efficiency of noise and vibration insulation; you can,
00:08:38
of course, do an overlap with vertical
00:08:40
stripes then yes, we can make
00:08:41
vertical overlaps accordingly, and
00:08:44
also if you look at when, but what kind of
00:08:46
technological holes do you have in the door, how
00:08:47
convenient is it for you, rolling it all out with a
00:08:51
roller should be convenient, in principle,
00:08:53
this way and that is possible, but the essence is clear that
00:08:54
we just need stiffening ribs that
00:08:56
improve our design
00:08:57
increases efficiency the costs are minimal the
00:09:00
result is maximum regarding as you
00:09:02
understand what I said inside the door there is a
00:09:04
lot of moisture accumulating so the
00:09:06
materials are noise insulation they are
00:09:08
usually very soft porous
00:09:10
materials so glue it inside the door what is
00:09:13
this similar in type up to comfort
00:09:15
software 15 millimeters of sense no,
00:09:17
yes, it has a good adhesive layer, it
00:09:19
sticks very rigidly, even if you
00:09:21
degrease everything and glue it there, it will work; the
00:09:24
sound insulation simply won’t work at
00:09:25
all, why because it will be
00:09:28
completely saturated with moisture so
00:09:30
that in the morning, glue only the excess weight, which is of no use
00:09:33
at all will lead, of course, there is
00:09:35
software type material in which
00:09:37
the top is rubberized, that is, they have a
00:09:38
closed support, the so-called
00:09:40
splen type, they look like we will show you
00:09:42
photographs,
00:09:43
well, let’s say, in any case, by their presence
00:09:46
and three doors, in our opinion, well, let’s
00:09:48
say, minimal results, so the
00:09:50
sound insulation of the doors is glued and we, in
00:09:52
principle, do not recommend it at all, that is,
00:09:54
only vibration, our task is to remove it when there is a
00:09:55
sound, we will glue the glue on the side of
00:09:58
the trim, so inside
00:09:59
the door, in principle, you only make
00:10:01
stiffening ribs, close the trim, then you
00:10:03
move accordingly to that part of
00:10:04
the door where the technological holes are
00:10:06
maybe we talked at the beginning of the video
00:10:08
and, in principle, that’s all in terms of
00:10:12
vibration isolation, now let’s move on to the
00:10:14
casing itself, that is, in the ideal case,
00:10:15
of course, the speaker itself is attached to the
00:10:18
wall that I was talking about, that is,
00:10:20
the speaker flutters precisely on the metal of the door,
00:10:21
not on the casing, some are screwed onto
00:10:23
casing, if you have a podium, let’s say,
00:10:25
which is screwed onto the casing from above,
00:10:26
then we are already working on the liquid in
00:10:29
the place where the speaker itself is attached,
00:10:32
regarding you, according to our
00:10:33
casing itself, in any case it has
00:10:35
some kind of shape, it has, accordingly,
00:10:37
standard clips
00:10:39
to which it holds what we have on it
00:10:42
since in any case it is made
00:10:44
of plastic, the plastic material is very
00:10:46
light and at the same time it has a
00:10:48
much higher resonance here, again, if our
00:10:51
speaker plays mat 80 hertz,
00:10:52
respectively, the resonance, let’s say so, the fs of the
00:10:55
casing itself should be below 60 Hertz,
00:10:57
what do we do for this and take the remains of
00:10:59
our 3-mm vibration, you can
00:11:01
of course use a two, depending on
00:11:04
whether the distance between the
00:11:05
casing and the door itself allows you, and partially
00:11:09
tapping the casing itself in the right places, you
00:11:11
glue the sheet and vibration insulation, well,
00:11:13
let’s say you’re there somehow then this
00:11:14
will work out, that is, you have partially betrayed the
00:11:16
casing to the mass; it has a large
00:11:19
mass, as we know, the greater the mass, the
00:11:21
lower the resonant frequency of any part,
00:11:24
reasons to what is in any part in
00:11:26
any case, so you removed everything on the doll,
00:11:29
taped vibration insulation in places,
00:11:31
tap the casing itself in the same way, you
00:11:33
can and the beast so that the money doesn’t ring, doesn’t
00:11:35
rattle if there is some kind of extraneous sound,
00:11:37
that is, in any case, add
00:11:40
vibration isolation if the speaker is already
00:11:41
connected to you, you can just take a
00:11:43
sine generator to run the purity there, let’s say
00:11:45
there from 40 hertz there to 500 hertz and monitor
00:11:48
there and if some ghosts of your
00:11:50
car tickets are the ideal option, that
00:11:52
is, we eliminate what really rattles and
00:11:54
rings, they just glued it
00:11:55
eight layers of Shumka and everything is cool
00:11:57
cool you won’t have it, so the
00:11:59
technological holes like we burned were
00:12:00
sealed, they partially sealed the vibration isolation of the
00:12:03
casing itself and the material is already glued to the casing itself,
00:12:06
just comfort
00:12:08
itself, for example, which is made with
00:12:09
pyramids, that is, pyramids, what is their
00:12:11
advantage, as we understand, the pyramids
00:12:14
should be directed towards the
00:12:15
sound source, that is, we just have
00:12:17
the casing covered with pyramids
00:12:19
directed inward of the door, that is, the noise from
00:12:21
we are coming from this side,
00:12:22
respectively, the sound wave came,
00:12:24
it in any case fell apart there into
00:12:26
some smaller ones and in any case, the
00:12:28
sound absorption coefficient due to these
00:12:30
pyramidal structures will be much
00:12:32
higher, film is used and such materials
00:12:34
are usually thermal insulation and have nothing to do
00:12:37
with noise anime, that is, the
00:12:38
sound absorption coefficient is simply 0 3, the
00:12:41
spleen itself is a very old material,
00:12:43
so to speak, before the old development, it
00:12:45
constantly peels off from the water; it has a
00:12:47
bad adhesive layer, so glue it
00:12:49
on the outside, that is, again, it gives a thickness
00:12:51
that does not wrinkle and you would kind of
00:12:53
use car audio doesn’t make any sense at all,
00:12:55
it’s thermal insulation, noise, there are
00:12:58
four sheets of captivity, you will have
00:12:59
one sheet of your software 15 millimeters, that’s why
00:13:03
we
00:13:05
recommend gluing this material to
00:13:08
the skin itself, why the power of these are pyramids,
00:13:11
as I said, they don’t have the maximum
00:13:12
sound absorption, respectively, one of
00:13:14
its functions is anti-slip at the same time
00:13:16
when
00:13:17
we come back with such a model, that is, the
00:13:19
material is very similar, so any
00:13:21
vibration, so to speak, between plastic and
00:13:23
metal will be completely removed, this is the
00:13:25
first and second most important factor or
00:13:27
even 3 to 1 noise insulation 2 anti-creaking and 3
00:13:30
properties cons what are the disadvantages when you put the covering on in
00:13:33
some places it fits very tightly
00:13:35
accordingly the captivity does not allow you
00:13:36
to close the covering the whole thing sticks out
00:13:38
looks very similar to and is usually not
00:13:40
effective this thing it wrinkles very easily
00:13:43
so we need in some places
00:13:44
you just have to doubt, calmly close the
00:13:47
casing, there won’t be any problems with this,
00:13:48
so you’ll be able to say that in a full-fledged way,
00:13:51
if we put vibration isolation there, it’s
00:13:53
30-40 percent of the total
00:13:56
noise area, and of course, just like an anti-creak, before
00:13:58
you cover the area of ​​the
00:14:00
casing itself, that’s the most important thing moment in
00:14:03
principle and the final one before in this
00:14:05
video, this work is on the clips themselves,
00:14:07
that is, the places where the clip itself
00:14:10
is stuck into the casing should be
00:14:13
treated with either this or that
00:14:15
material, that is, this is a regular anti-creak, we have it
00:14:17
like electrical tape, it has a good
00:14:19
adhesive layer you all these sheathed glasses were
00:14:21
pulled out, trimmed as much as possible with
00:14:22
scissors, the comforts of life itself and
00:14:25
accordingly treated right from above along the
00:14:28
perimeter of the swelling itself in this place,
00:14:31
anti-creak and if a
00:14:34
place does form somewhere, that is, along the perimeter and where is the
00:14:36
maximum, let’s say, the probability of creaking
00:14:38
and if it’s still software yours is not in this
00:14:40
place, you can
00:14:41
glue this casing around the perimeter like electrical tape, well, that
00:14:43
is, ideally, do it so that it is not
00:14:44
visible from the outside,
00:14:45
otherwise it will again look like
00:14:47
a collective farm, in principle, this is how we say
00:14:49
the most effective option for
00:14:51
soundproofing the door, come up with something
00:14:53
more serious, of course it’s possible, but let’s
00:14:55
say your amount of effort that you
00:14:58
will spend and the amount of result it wo
00:15:00
n’t be so big here you
00:15:01
spend
00:15:02
a little effort maximum result
00:15:04
everything that is glued above with the help of other
00:15:06
materials more expensive so let’s say
00:15:08
more competent modern ones which are
00:15:10
imposed by marketers, again, is already
00:15:12
a result it will be a little bit better, but
00:15:14
your efforts and your budget will increase
00:15:16
extremely higher,
00:15:17
so this is the option that we
00:15:19
have if you read there specifically
00:15:21
how much vibration noise we get, that is, the
00:15:23
comforts of the phone are very
00:15:25
large in size, they cost there, they are there, and there are
00:15:28
two brands articles from Aura are a
00:15:30
more budget option, it costs 570
00:15:32
rubles per sheet and I from comforts of the
00:15:34
phone costs 750 rubles per sheet,
00:15:36
yes, it’s expensive, I agree with you,
00:15:38
again, taking into account the absorption coefficient of the
00:15:39
pyramids themselves, the anti-creaking function about this,
00:15:42
in fact, let’s say very much the
00:15:44
cost-effective material is not smart, that it is, so
00:15:46
to speak, not cheap, but the
00:15:48
sheet size is 1 meter by 0 7 out of 5 meters, that is,
00:15:50
it is very large 0 75 square meters
00:15:53
before we get it, so
00:15:56
three of these sheets will be enough for you for 4 sheathings,
00:15:58
that is, the front one comes out of full-fledged
00:16:00
sheets because to evict and from the front,
00:16:02
after all, all the noises are more tied to the
00:16:04
front passengers, in particular the
00:16:06
driver, and you use the remains of the material
00:16:08
on the back door, so
00:16:10
in ours, let’s say, yes, in our invoice there
00:16:12
will be release the comfort in
00:16:15
iv 15 millimeters accordingly, it
00:16:20
costs us either 573 or 750 for 3 and the
00:16:23
second moment we need and accordingly
00:16:25
3 3 meter material, well, let’s say even the
00:16:28
same comfort comfort ovsky material
00:16:30
it could be auer it could be noise from a
00:16:32
bunch of different brands there are already some that but
00:16:34
in fact from the material in terms of
00:16:36
relative to its price is inexpensive and
00:16:38
already gives a good result, that is,
00:16:40
the cost of a sheet is 200 rubles, we take
00:16:42
10 pieces, that is, 10 sheets m 3 millimeters,
00:16:45
of course you can use a camera of twos and threes, but well, let’s
00:16:47
say in any case you will find a
00:16:49
place where it glue it on the trim,
00:16:51
it’s thicker than it, just in pieces,
00:16:53
come in the right position, so let’s say knock,
00:16:55
nothing rattles, doesn’t ring, it
00:16:57
turns out to be two thousand rubles, we
00:16:58
spend on 4 doors, in any case, on
00:17:02
the front door it will take more
00:17:03
vibration isolation of the rear door, they are smaller in
00:17:05
area and so let's say their glue is
00:17:07
no longer as cool as the front ones, so
00:17:09
10 sheets, most of them are on the front
00:17:11
door, a smaller part is on the back,
00:17:13
so on average, let's even
00:17:15
charge 700 rubles per sheet there, 3 sheets
00:17:16
are 2100 rubles,
00:17:18
2000 rubles you have the sound insulation itself and
00:17:23
there is 1 to 2 packs of anti-creak this is 100
00:17:25
rubles max, that is, in the area there is 4200
00:17:28
rubles your final budget for all
00:17:30
the materials that are planned here without
00:17:32
taking into account the rollers the roller costs 200-300 rubles
00:17:34
a piece, this will be the maximum
00:17:36
result in terms of sound in terms of your
00:17:39
comfort, that is, you will be part already
00:17:41
when closing the door, go to
00:17:42
your car and close
00:17:43
it more tightly, we will play a good sound
00:17:46
when closing, this is maximum comfort at
00:17:48
high speeds
00:17:49
in any case, but without taking into account
00:17:51
the roof, of course, this is a separate conversation today
00:17:53
we only have a video about the doors and well, this is how it
00:17:54
turned out you understand, it’s very
00:17:56
long, a lot of information may need to be
00:17:58
reviewed several times, that’s why
00:18:00
from the point of view of sound everything is
00:18:02
fine, from the point of view of simply everything
00:18:04
is fine minimum budget
00:18:05
maximum result so write and
00:18:07
put your likes dear friends
00:18:08
