Why horns and musical instruments have this kind of burning. To answer this
question a year ago I decided to take this and compare it with this but I have
never done such a big thing on my channel before as usual we decided to do a
small model to see what we can do learn about the challenges that can arise from
growing all the way. -gel and put three layers of fiberglass and Polyester resin
and when you come out of the mold, you are left with this We are quickly struck
that there is actually something very special about this system So I will change
from my lav drum to my gun spear for this display Here is my usual voice .
Here
is my voice as I use the tube to show that there is more going on here than just
focusing on one side. Here is my voice using the horn. You can even hear me
whispering ... which is annoying. This was proof that the curved shape of the
horn had a big impact now it's time to really measure things down to the great
horn of the beast We've done using all the same principles We learned from the
example and headed to the ruined place we could find on Google Maps to put it
together [Some cool music] Mark's assistant: "You hear me" Mark's assistant:
"Hello there!" Mark: "It sounds like you're on my shoulder" As you know, the
horn base is responsible for creating all the sound to see what's inside I
thought it was worth opening with my friends Dan and Lincoln from the popular
YouTube Inside channel. And it turns out that it's really simple: the key is
this small metal plate with a circle or diaphragm. So the air enters here at 100
psi and passes around the diaphragm in such a way that it causes it to move 110
times per second causing the corresponding pressure wave to shoot down here down
the throat of the horn.
8 months later None of us had ever heard a fire but
Lincoln hadn't seen anything because we made him wait in the car Mark: "This is
a great revelation" Mark: "Are you all right?" Lincoln: "Wow, that's great!"
This is actually not, it is. Opinion, you can now read [Lincoln:] Wow! Before we
heat it we must first talk about how hearing works and what I have finally
learned about why the horns have a curved shape. when you see movement on the
other side of the jello block and that's where your eardrum is So go back and
forth at the same rate as the horn horn because of all these jello collisions
the molecules between these are called pressure waves and the way sound travels
in the air so if the horn diaphragm beats air molecules at A high frequency or
more often our brain determines that as a high voice But when accidents occur at
a low or very low frequency our brain determines that as a low voice. OK But why
does the curved horn stand still? Well that is related to the so-called
impedance. Basically, the horn of the horn is strong and strong and pushes
towards the air which does not give much resistance. It does not work as well as
trying to break a piece of paper by hitting it. You can still see that the jello
is moving in the opposite direction Not so much because the air is just thinner
and weaker than this small area So to have a better visual connection with the
air you put a great curved shape just after the shock You see now that your ear
is moving forward and forward with great force because the interface best so the
sounds are most audible with the curved horn not because you amplify the sound
but because it saves the sound this makes sense because it amplifies it means
you can add power to the system and there are no battery or plugs on the curved
part of the horn.
air in a store that works better the chain reaction of
molecules entering your eardrum And now the horn Isn't that so loud? Lincoln:
"Wow, that's great!" Is that too good? This is actually not, it is. Vision, now
you can read [HORN HISTORY] [high horn sound] [laughter] Oh my God Like eight
months of work It's the first time we've exploded and that's behind the horn.
Dan: I felt a vibration. Okay So this is about two football fields away from the
province. We don't know how big this sounds here. Okay Ken, burn the normal air
horn (Wind Horn) Yes, we could feel now that we have a little bit of fear that
you can feel it right, okay, we're shooting [BIG horn shooting] [laughs] So in
our second test we went about a distance. miles (1.6 Km) and you will never see
the horn here Alright, Ken fire. [Blow the horn] Lincoln: We can still hear it,
that's crazy. You'll never see that big horn, but it still sounds great. So
let's continue driving We go very far So from the view of the satellite This is
where the horn was Here it was in the first place then the second place and then
here the third place 4 km from there Okay, so the horn is now too far away. I
really can't see with my own eyes. Duma: It's too far Duma: I see a little. It's
in the middle of the hill. There is a small piece and it is there We will
experiment and check the speed of the sound We should hear it in this
walkie-talkie and then some time later we can hear it from this distance Lonna
will measure the time on her stopwatch and we should be able to calculate from
there where the sound speed is Ready when ar ar [pause] Mark: Wait Vmmmmmmmm
That's awful! How long. It took 11 seconds for the sound of the horn to reach
here. I think we can go 10 miles further What do you think this means? It took a
continuous series of air molecules two and a half miles for 11 seconds all
colliding until they came down here and collided with the air molecules in the
ear canals and hit our ears Hi! Wait, if I cry? [Shouting] So the Sun was going
to set fast But before we went home We wanted to try to break some glass and if
you want to break the glass with a little air-tight trick is, to get its sound
frequency.
You really know all about this If you have ever used one of these I can make Eliza go really high with a little bit of strength just now if I use that power from time to time, it doesn't do much. It's not fun, huh? No, it's not fun. But if I use the same amount of energy as the natural frequency of throwing that little push ups add up Mark Rober And so this time the resonant frequency increases our fun, but if the engineers look at this it can lead to disaster as when the wind blows at the right rate destroys Tacoma Narrows Bridge That's why also soldiers do not walk together when crossing the bridge So if you measure the frequency of the glass with an accelerometer like this Then you just need to make sure your horn is blazing at the right time or repeat there or You can just change the frequency of the glass to match your horn Glass break] Shoutout to Lincoln and Dan from What's Inside to help me. Investigate what really is inside the old Japanese air siren with their video? It's a completely different way of making the most audible sound So you should go check it out to use the link in the description This horn is easily the biggest thing I've ever built my own station and it took eight months to work with my previous NASA. friend Ken to get it out The problem is that Ken lives down here by NASA but I live 400 kilometers this way So I teamed up with Portal from Facebook to better collaborate on building and process design So he set up a workshop in his workshop I built a portal plus mine and without the sound of high fidelity Video HD. I think the coolest thing about the portal is the smart camera feature, which you see working here So as I was walking around my workplace and Ken circling his camera frames the video kept us both together and this is good for us because 'we don't always move the cameras back or forth. and smart sound amplifies our voice as we move around so we can hear each other no matter what other store noise [Download Diaphragm] [Laughter] And then when it comes to any device at home, privacy is great So with one touch portal it will allow you to interrupt both camera and microphone or if you choose analog solution They offer camera cover Also, smart camera uses AI technology that works in the portal area and not on remote servers. At the end of the day, it's a good piece of hardware and it works really well so if you want to learn more about the Portal or maybe get yours just keep using the link in the video description. Thanks for reading.
