At 3:00 in the morning the loudest sound is KZfaq ads

Damn, I never even considered mere air displacement as an obstacle to teleportation!

Concerning the teleportation intro, I'd always imagined that such a device would isolate the matter between two places and swap them. Where you used to be would be instantly filled with the air (or water or brick wall or whatever) of wherever you're teleporting to. You'd get a nice "pop" teleporting between two locations of different air pressure (seaside to top of everest or vice versa), but your scenario of bursting eardrums would only happen if someone teleported to empty space, which doesn't sound fun for the person traveling.

At around 1100 dB is where the fun starts to happen.

Krakatoa at 170 or 180dB is an oft repeated mistake. It was 172dB 100 miles from the source. That equates to around 300dB at the distances the other loud noises are measured at. To compare loudness you need to state how loud and how far. If you don't say how far at the source is implied and Krakatoa, or any large volcanic eruption come to that, is WAY louder than 180db at source.

My fart is about 150dB i hate it when i shatter a toilet seat. Lots of cleaning and explaining afterwards...

So coupled with teleportation you'd need the technology to take the atoms at the location being teleported to, and have them essentially swap places simultaneously with the object being teleported. This would both fill the void left from teleporting, as well as make sure the object teleported isn't crashing into matter present at the teleportation arrival point.

Wow, I literally just learned about the mathematics of sound in physics today

That ending man! What a Dick! Haha

This teleportation-air displacement-sound thing is a thing in "So You Want to be a Wizard" which is a fun series and it tries to be somewhat scientifically accurate and I highly recommend it to anyone in that age range. When they teleport in those books it doesn't do the eardrums bursting, nausea inducing part, it just makes a loud bang.

omg that's something I've been wondering, whether or not sound could go faster than the speed of sound or would it become inaudible. You answered all the questions google couldn't thank you!

there's also the problem that "teleporting" wouldn't be teleporting. It would be scanning everything in your body's exact position, destroying everything in your body, then constructing an exact copy of what was just scanned somewhere else, made out of different particles. In other words: you die and an exact copy of you lives on.

When i stub my toe the intensity of my scream can knock out an entire nation

2:21 look at the clouds!!!

The spinal tap reference was on point

Of COURSE it's higher than "11" - my Marshall stack goes to 20

Then.. shouldn't minecraft teleporting give anyone nausea nearby?

the ending was like a slap on the face

I thought about the sound problem with teleporting, I assumes the air would switch places with you because otherwise you would have air shoved inside you which... would also be pretty dangerous. Also just gonna say, the loundness in decibles is really hard to be certain of because coming right to it makes it almost infinite, and it quickly goes down. Big enough to kill anything *queue earth explosion* in a few meters

Please make a video on why we cringe or shiver to some sounds and why do some smells make us throw up. Maybe a whole video on our senses and weird things about them. Thank you for considering my comment!

This was really interesting. Thank you.

What if you do it the way Star Trek does it? Its pretty gradual... They don't just disappear.

Liked the intro and the channel name. Subbed

Hey, man, I doubt you will read this comment, but HOLY CRAP you have improved on your inflections. Like, seriously: I watched one of your old videos and I could barely tell that you were the same people. Nice job!!!

2:59 SIL in excess of 200 dB was measured directly at the launchpad site during Saturn V (Apollo 4 mission) launch. From other acoustic measurements it can be concluded that at ground points 1000-1500 m away SIL dropped below 150 dB. Still extremely loud, but no grass ignition possible with 150 dB, at any sound frequency

Great video! And on my birthday, too.

Really cool episode

Hey, they have Heisenberg compensators. I'm sure they can manage to compensate the pressure difference as well.

you need a lot more subscribers! you need at least 1 million

Great video!

I would assume that anyone designing a teleportation machine would have the wisdom to make it work both ways. This is, if you teleport all the atoms in one space to another, you also teleport the matter back to other end. It would also prevent deaths due to lets say, teleporting someone into solid rock. Once the teleport is complete, if you have a statue of stone in the shape of the person (or the teleportation bubble) you just teleported, better reverse it quickly before that person suffocates.

Thanks for the ending👍

Nice vid! Keep going

Cool video! Very interesting

Thats crazy very interesting topic very educational

I'm pretty sure the loudest sound is my mom yelling at me

At 1:00 he begins talking about sound pressure, however I think that the equation he uses for intensity is actually an expression of power applied over a volume.

woah, was that red's indoor range?! neato video as always!

If you teleport,the air on your destination goes to your previous place to avoid vacuum.There will be tiny differences between two air masses and might make that whoop sound.

Can you put a link in the description for the video shown at 2:20?

Your collapsing void shockwave assertion reminded me of a video the slo-mo guys did with Destin from Smarter Every Day where they fire guns under water in a swimming pool. In the wake of the bullet some feet from the muzzle a string of progressively smaller vacuum bubbles oscillate into and out of existence while the shooter is in the pool with no ill effects. Maybe you would break the eardrums of someone you were snuggling or grappling with if you suddenly popped out of.. that frame of reference, but I can't see it being any more violent than a similar sound produced when a large firecracker or firework suddenly produces a volume of gas similar to the volume of your body within a few meters. I'm sure it would be damn loud, but nausea and permanent injury? I doubt it.

What is the loudest possible sound *Dropping your spoon at 2 AM.*

Interesting video!

"The last sound you will never hear" haahaa

thanks that was entertaining!!!

The loudest sound I've ever heard.. was that THX logo playing in the cinema. That was damn loud that I am commenting this in heaven right now.

The teleportation would have to go two ways. You switch with the air molecules in the place you teleport to

The sun is SO POWERFULL that if space carried sound as well as the atmosphere, we would hear a constant 100 db roar that you could never get away from.

"The last sound you never hear" So badass. =D

Did you guys know that scratching your nails on a chalk board makes a sound? I always wondered why people freaked out when someone did that.

GREAT VIDEO

HAHAHAHA They totally need to make a whole movie where the main guy teleports for a living and it literally does that every time, sending everyone around to the emergency room! #popman hahahahaha

i never though about it. great

I love how excited joe got with that decible reader thingy... Lol

i like how this episode is more vsauce like. more! continue in this direction!

awesome video *thumbs up*

Just realized (thanks to the shot of I35's upper decks and Red's Gun Range) that you are in Austin. :)

I work as a ramp agent. Ouch... if you forget your earplugs as the plane is pulling in or as it fires up it's egines to drive away to the hangar or the runway... the sound is so loud it's painful.

Random fun fact: The loudest fart ever recorded occurred on May 16, 1972 in Madeline, Texas by Alvin Meshits. The blast maintained a level of 194 decibels for one third of a second.

0:07 that's the 90's Talk Show background from Ryan George!

That depends on how fast you are teleported. If it's a slow gradual teleportation then there's the space where you used to be will fll more slowly with air than if you disappeared quickly as in your vid. In Star Trek fictional universe it always occured slowly.

@2:35 You actual, outright legends !! 🤟🏼😂🤙🏼

I would love to know how a lighning strike would sound on all of the planets in the solar system!

Whoah. Never heard about that thing with the space shuttle. So, it can make a sound so loud that it _rips itself apart_? Dude! Also OW at the end there. And at exactly that frequency that feels like it's boring straight through your skull, too! (thumbs up)

The dynamic range of our hearing system is incredible. Ranging from the width of an oxygen molecule up to a billion times, 9 order of magnitude. How is that system work? The cochlea is converting sound to frequency. The sensors near the input for high frequency (4 KHz), the center of the "escargot" for low frequency (200 Hz). But the official dynamic range frequency wise is from 20 Hz to 20 KHz, 3 order of magnitude. This ratio of frequency range can be approximated as 10 octaves ; multiplying 2 by 2 by 2... 10 times, giving 1024, close enough to 1000. How can we hear such wide dynamic range in sound intensity? The answer is, according to wikipedia, positive feedback. There is 3 times more motor cilias than sensor cilias. As soon as a sensor detect motion, the motor cilias would start moving, allowing to excite more cilias. Positive feedback is the generic way to create oscillators. Something start moving, and, in an attempt of restraining it, an effector over react. After a delay, the sensor detect the opposite and the effector over react in the opposite direction. Cruise control are an example of "perfect" reaction. When going uphill, the controller push the gas pedal just enough to maintain a stable speed. Under reacting is a motor so weak that even pushing the gas pedal to max, the car will slow down on uphill. Here is how our head get wide dynamic range: As a sound wave enter the cochlea and the first sensors detect it, the motor cilias start moving enough to cancel the wave. Next, lower frequency component continue moving in the cochlea. Eventually, other sensor cilias detect and, like before, the closest motor cilias fight to neutralize the wave. This repeats until every high frequency component have been filtered out and only 200 Hz or less remain. That low frequency wave turn around and travel in the other chamber, where the motor cilias are located. It reaches the round window and possibly bounce back. Conclusion: The sensor cilias are representing a very distorted version of the sound wave. However, the command on the motor cilias is a logarithmic scale of sound intensity at a given frequency. The oxygen sensors in cars is an example of that inverted logic; there is temperature sensor and a heater. A control loop modulates the current trying to maintain the temperature constant. The oxygen level is calculated from the energy used by the heater instead of the temperature measured by the sensor. I discuss on quora about cochlea. I think you could be the first on youtube to explain how our ears really work!

I think human vision goes from single photon detection up to 10^15 photons per second or more before you hit damage thresholds, giving vision a claim for largest dynamic range. The human hearing threshold is about 10^-12 W/M^2, and the damage threshold is around 1W/M^2 The way energy is detected and compensation mechanisms are so different that a comparison in these terms strains what is reasonable.

awesome vid

I was hoping this wouldn't devlove to the level of using dB SPL to quantify loudness - but I was sorely mistaken. This doesn't answer the question the way it should - although right at the end you summarise that anything beyond x dB becomes a shockwave - it still leaves people open to interpreting dB SPL as a quantifier for loudness, which is just a subjective experience. So, "What's the Loudest Possible Sound?" : something capable of using a person's A scale frequency response to its optimal performance before physical limitations become an issue.

spinal tap reference earns you eternal respect

I was reading up on quantum mechanics, because I stay curious. And scientists think that if you were teleported to a diffrent point your old self would be destroyed and basicly make an exact copy of you except not.. Science you crazy. Also my science teacher shows my class some of your videos and you make it easier to understand things like how vaccines work and stuff ( One Of Your Recent Videos ) please do an episode on black holes I find them really really interesting and I wanna know your input! :)

Possible teleportation solution. Teleport the subject to one location, while teleporting the air from that location to where the subject was teleported from. No vacuum.

I always assumed teleportation would swap you with whatever is at the target location rather than just move you exclussively.

So how many decibels would the bang be that you'd cause by transporting?

A teleporter might work if you replaced all the matter in the area you were at with the area you are going to

I grant you that collapsing air might be harmful, but if one had the ability to teleport matter from point to point it would be safe to posit that the collapsing vector would be replaced with whatever was at the target location, or even just null air.

Trying to listen to video to fall asleep, then. BAM! BAM! BAM! ... Not my best idea watching a video on sounds to pass out😓

I read that back then Krakatoa spewed out volcanic stuff into the air real fast. Lol you could probably hitch a satellite with only a small tank of fuel for the jump start.

Thanks

I was expecting you to say something like, "there isn't technically a loudest sound, the sound just needs to be decently loud, and it all mainly depends on the distance from your ear after. say you hear a gunshot directly one centimeter away from your eardrum. I'm pretty sure you would go deaf, because if you hear a gunshot across the world from you, you wouldn't hear it at all. it would basically be the quietest sound ever." I know what I commented is probably the stupidest thing you ever heard. (probably) but to me, this is just a regular educated guess. Am I right, or am I wrong?

You could almost say teleportation would leave behind a loud noise like a car backfiring or a loud popping sound, right?

1:51 one reason I don't like indoor shooting ranges lol

THX

"decibals" sounds like "decimals", but with a cold.

fascinating

Is the loudest sound possible also dependent upon the frequency? For instance, is 194 db at 20 Hz as 'loud' as 194 db at 20 kHz?

Am I right in saying your diagram for a 'wiggling' sound wave is wrong? I believe sound waves are compressive (like an accordian) rather than transverse (like a wave in the ocean)?

at 2:02 Krakatoa is not in south Pacific,but SE Asia part of Indonesian Archipelago

*Vacuum Cleaner:* 70dB *Garbage Disposal:* 80dB *Ear Exploder 9000:* 9000dB

loudest possible sound: the mosquito near your ear when the fan is off

Would "sonoluminescence" occur on dry land like it does under water if you were to vanish in an instant?

When you "teleport" wouldn't the air where you teleport be swapped with the air where you used to be? Assuming you can teleport, and that this process was instant, you can't teleport in a place where air already is. The only logical situation is to swap your body with the air in the new location. And the air in that location would fit perfectly in the empty space where you used to be. Or make the process slow and gradual that you push the air out of the way, and this would make the space where you used to be shrink slowly so no explosion anyway

0:09 what if you teleport that has air around it can your molecules and the air molecules switch places? then would the air collapse happen?

I always wondered about this cuz I wanted an explanation as to why my favorite X-Man (Nightcrawler) leaves a cloud of gas whenever he teleports. And so I figured that if he didn't, there would just be no gas at all, and this a vacuum and everything within a small radius of where he was would briefly get sucked in. But then what happens when he arrives at his destination? Does his body push all the air away? Does he absorb the air? Is that gas cloud he leaves behind the air he would've taken up, but he just teleports it to where he was???

Or we could teleport the way the main character from Jumper teleports, through a "door" of sorts, at least that is how it's described in the book. In the movie, it's a worm hole type thing called a "jump scar." If we use the method from the book, there won't really be that vacuum when we teleport. If we do get teleportation, this is my preference on how we do the teleports.

more on the teleportation sound thing

For those too lazy too look it up, the maximum sound level on Venus would be 233 dB. Since Saturn doesn't really have a defined "surface" I considered the transition from gas to liquid the "surface" and got a shocking number of 320 dB at this level!

these go to eleven. Loved that reference to spinal tap

First thought before clicking this video, "Is it okay to wear headphones?"

194 dB is the upper limit of undistorted sound (i.e. maintaining a sinusoidal pressure profile). That qualification should have been made. Sound of much higher decibel level can be produced.
