When you have tinnitus like me, the quietest place on earth sounds like this "eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee"
Its God awful I relate
@Pearlwind nope it's still eeeeeeeeeeeeeeeeeeeeeeeeeeeee like a freaking fax machine in your ear at max volume for hours
Oof
try having turtle beach headphones on, angle the headphone pieces. have someone turn on sink for maybe 30 seconds......tinnitus go reeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee!!!!
Makes me regret not wearing ear protection in a machining workshop
"I'm a bag of noise" best phase ive heard all year.
"Phrase" 2y grammar nazi post
Should’ve been sponsored by “A Quiet Place”
Calebunga i was about to sauf that☹️
I was also going to say something like that...
I got a ad about the quiet place 2 before the video
ikr
i was about to like, but I realised that it had 420 likes

"Ah, I'm a bag of noise"
Kyle Hill 2018
Best phrase to describe owls ever
That's me 100% LMAO
I'm telling you, you don't realize how much noise you make until it's dead silent.
Can More ppl Like the comment of this guy ? I acually tried it . You are compeletly Correct
Everyone living in a house at night, and you try to not make a sound, and everything sounds like a gunshot.
#getKyleonTheExpanse
When you're trying to get a midnight snack, even closing the fridge sounds like a trumpet
That's terrifying
“adorable little hooty boys” is probably the cutest sentence i have ever heard. thank you, kyle. you just made my day.
I've been in that room. It is unsettling. You don't know your ears are ringing until that ringing is like everyone in a theater whistling the same tune. You can hear your hair rustling (I have centimeter length hair). You can hear the tendons in your body making popping sounds and creaking, You can hear your blood pumping, you can hear your eyeballs moving. you become aware of your nose and mouth airways, mucus in your nose blocking your airway or the slight rasp of inhaling. I sneazed in there and it was almost painful because i was more aware of my body convulsing to do the action.
Seriously, You wouldn't last a hour in there. I could see it as a torture chamber or asylum room. It would drive you INSANE in Seconds! But you gotta try it once. Makes you appreciate white noise, like air-conditioning or crowd noise
I went to a night club once, that was a torture chamber due to the loudness (and it also gave me permanent tinnitus). I'd prefer to be tortured in the other direction.
I really wouldn't, even though I probably can't hear it, I can still imagine some of these sounds my body makes that my body makes me uncomfortable.
A youtuber went there and stayed there for more than a hOuR but he got bored and left. Wish i could go there
That sounds awesome to me i would love to sleep in one.
HC C ur poor ass can’t afford to go in that room

If you are deaf then this would be the most boring roadtrip of your life
Me too
depends how deaf you are, also your friends would see how is like to be you for a sec
Mike Snapper
Imagine if they heard you say that 😠
By the way this is a joke
Mike Snapper Like the new movie silence
If your deaf I’m sure the rings and buzzes from tinnitus are the only things you hear. The ring is there because your Auditory Cortex is receiving no information from the hairs in your cochlea, as a result it doesn’t know how to respond so it responds with just a ring/buzz. Kinda like TV static on inactive TV channels, except it’s organic.
I love how this video is sponsored by the movie skyscraper and the video is based around the idea of the quiet place.
I loved the video, keep up the great work!!

What’s interesting to me is that even in complete silence you’ll still hear noises (ie the sound of your own blood flowing in your ears) but to a psychological side of it, it’s always interesting to hear what people say they THINK they hear in a silent room. Like when people are completely convinced a place is haunted so that even in a dead silent room (no pun intended) they swear they can still hear footsteps or voices when there are none because they’ve built that expectation in their mind so their brain will make it so. I wonder, if you put someone in a sensory deprivation chamber but build an expectation to them beforehand, how closely they would experience what they were expecting compared to the what actually is being heard or felt
Cj Rainbolt actually in complete silence our brains literally imagine sounds much like someone getting phantom pains from losing an appendage.
our brain doesn't like to be deprived of its senses, so people tend to hallucinate. now I suppose if the person is going to actually hallucinate and about what, it all depends on the suggestion you gave the person beforehand, since our brain will always try to work with any information it has. so its actually possible that if you think about something while sensory deprived, you can control your hallucinations. its a similar logic to lucid dreams.
I think it's just that people are misunderstanding what they are hearing. I used to think I heard footsteps when I went to bed as a kid and it really scared me until one day I realised it was just my pulse. I've been hearing my pulse all that time and I thought it was some ghost's footsteps.
Very first time a girlfriend slept in my arms, she rested her head on the side of my neck and could hear my blood flowing. She giggled at it.
She liked vampire stories.
Our brains are ultimately telling us what we see or hear. Its subjective. We aren't perceiving any sort of objective reality.
Instead of being quite, could we not just build machines that make a lot of noice?
So the monsters would be deafened and not hear us?
We could even weaponize that noise, probably. Overload their senses and they'll go deaf
Kinda what I was thinking too, use lots of sound to create camoflage. Or even make sonic decoys with high explosives... kill the close aliens and stun the ones farther back with the compression waves.
Where would you get the fuel to run it?
Uhm, why wouldn't they have access to fuel?
living in a city would make it a hell to hunt in for the aliens
"On the next episode of Thor sings Opera in a sound proof chamber..."
I was literally just smashing through my drums and then I start watching this so If I were in this movie I’d get killed instantly. I’m also a talkative person in general, and loud. And sometimes I snore
"Ahhh, I'm a bagga noise..."
The exact time I read this he says this
Hey Kyle,
So owls have specialized feathers that help them fly almost completely silent. Interestingly, there are also birds that have feathers that do the exact opposite.
Several types of dove actually have specialized feathers that produce sound when moved a certain way. The feathers are used as a warning to other birds and have even been shown to have different tones for different threats.
Thanks for the fun!
-Mike
Watchmiker that's seriously amazing.
Like how helicopters can change the "attack angle" (literal translation, not sure it's correct) of their blades to change the sound produced (and other more flight related reasons). An interesting one being to annoy/scare people at a demonstration or a riot.
10:20 thats a jim carrey moment 😂
I always hear a ring in my ears 24/7 so I have no clue in the world what Silent is
If there was an extraterrestrial race that had hearing sensitive enough to hear us from miles away, we might be able to beat them by being extremely loud. As in, sonic amplifiers turned to 15 loud. If they had ears that could hear quiet sounds from long distances, then it could be reasoned that extremely loud sounds from extremely short distances could permanently damage their ears, or even kill them. If that were the case, we'd be able to fend them off by shouting at them through megaphones, speakers, etc. Present Mic style, which would not only be awesome, but hilarious in retrospect.

(I haven't been able to watch the movie, so this is wild speculation at best. Please, correct me if they address this in the movie.)
I've seen a bunch of comments saying things like this one, but if the point is high decibels, why not just scream bloody murder when one is nearby? Human voices can hit incredible pitches in the right circumstances, and it's a build in defense mechanism we still use.

Could you please make a video on how cloak and dagger's powers work? I think it probably has a lot to do with quantum mechanics. I know almost nothing on this subject, but I know it can be used to explain teleportation. I also know that quantum mechanics have a lot to do with antimatter. I think that Tandy's light daggers are probably solid matter, whereas Tyrone's smoke stuff that can be seen surrounding him might be gaseous antimatter. This would explain how when they tried to touch eachother, it created a blast that sent them both flying.
If 1 gram of matter came into contact with 1 gram of antimatter, the explosion would be about as devastating as 2 Hiroshima bombs.
Dan The-Man So maybe there might be a SMALL hole in my theory...
I'd say space manipulation is at play with Cloak's powers, I can dive into it and get it to you in a few days
Its fiction,science is confused
If a tree falls in an empty forest, would it really make a noise?
Technically, yes, but also, no
It would make pressure waves. Sound, with noise being sound, is the brain's interpretation of an outside stimulus as it arrives at the inner ear. If nothing with a brain is around to interpret this as sound, or noise, then it's not technically sound at all yet.
@@asthecrowflies1201 ye but it makes the pressure waves
So yes, and no
@@WatermelonEnthusiast9 the answer is just no. There's no yes involved, unless it's not an empty forest, and that's the scenario you provided.
@@asthecrowflies1201 noise is just another word for sound, and sound refers to both audible sound and separately inaudible sound, so its a yes and a no
@@WatermelonEnthusiast9 you're totally right. I guess I wasted my time getting that bachelor's degree in acoustic engineering. I should've just come to CZcams. Maybe I would've gotten my job in the field earlier...
I haven't seen the movie, but someone told me about the waterfall setting. I wonder if anyone could set up an artificial sound "camouflage". They could place say a speaker hooked up to an iPod inside a cage, running this constantly until the creatures learn to avoid the area. Obviously the logistics of this would be more difficult than just a speaker in a cage.
Also with hearing that sensitive could people employ stun grenades as a way to disable them and permanently damage their hearing.
Logan Ballard unless these aliens have 3D hearing, and can tell the difference among the background like our eyes can tell the difference in visible light to let us see. Yes, a portable sound system should work as either decoys, or concealment.
Also flash bangs, and stun grenades should be overwhelming for these aliens. Not only do they have visual overload, but they would literally have the hearing equivalent of what happens to our eyes if not out right damage them.
Wouldn't that be fun if we could use high pitched noise to annoy the crap out of them or make them go crazy? I think we could easily outmatch these aliens.
If a creature had better hearing than us and was hunting us there is no way we could be quiet enough to hide from them. You could only hope to drown out our own noises with the noises of things they are not interested in, in the same way you can't hear someone talking in a noisy place.
It could be used as bait maybe. If electricity could kill them, use the sound to draw them in to traps to fry them. Likewise mines or if they were susceptible, poisoned food. Of course if they were reasonably intelligent, they might learn to avoid these things. Then it would be a matter of would they leave this area alone or be attracted to it and work their way through by weight of numbers overwhelming the defenses until some got through?
Kinda like Kyle Reese from the Terminator did in the factory, when he turned on every machine he could.
but remember there are still thousnds of things making noise like trees water rocks etc etc so they have to listen to spacific sound like crying or shouting and running
or els they would attack everything and smash their faces on everything
There flying is dead silent
Owl: REEEeeeeeeeee
A few years ago, my hearing was tested by an ENT (ear, nose and throat doctor.) I was able to easily and consistently hear sounds at 0 dB. I CAN hear a watch at over a meter away. I can hear a clock tick through a wall. It’s not easy having hypersensitive hearing. Sounds most people take for granted can be uncomfortable, or even painful, for me.
If these aliens are so sensitive to noise then surely you would not even need to be noisier outside as the human body makes all sorts of noises (as you mentioned about your teeth) so as with some animals they should be able to even hear your heart beating. So the scene where the alien was in the bathroom she would be alien food because not only would her heart be beating it would be even louder due to it beating faster, so much so the alien could possible hear it rushing through your body. Also the longer you hold your breath the more your body has to work again increasing the sound. Ohh yeah so my point is if an alien is in the room or close by it would not matter how quiet you are, you are gonna be eaten.
instead of being quite make really loud noise would fucked the alien ears since they are very sensitive? like play really loud music? lol
EpicWins its time for linkin park song or korn XD
No offense, but how about you guys watch the damned movie before commenting? Seriously if a predator has evolved adapted and, most importantly, THRIVED upon hunting via sound, then this creature will know how to protect it. If i'd be mean, i'd suggest that if you have eyes, why aren't you staring at the sun?
TheKueiJin then its more weakness than it should be just turn on multiple speaker on your surroundings set it up force them to close their damn "ear" they won't hear you plus if their way closing their not instantaneous, doesn't surprise gunshot make them deaf? ( if the way they hear is like toph form airbender i give up.)
that is what i have been thinking too, with all the loud machines running in cities, car horns, car engines, planes taking off and landing, construction work going on, dogs barking, trains, trucks, busses, there is no way these things would know where they are without at least one additional sense to complement their hearing abillity.
no creature on this earth functions entirely on one sense, even the most specialized still have another sense that kinda still works well enough to function as a backup when the main one fails for any reason.
So I watched the Ant Man Footnotes and then this episode on Tuesday - woke up at 4 AM from a nightmare where an angry woman quantum tunneled through my front door because I was making too much noise... So, thanks for that... :P
I love the on-site stuff! Great episode :)
This was a really cool video, Kyle. I really enjoyed the field trip! Love the work you guys do, keep it up!
Omg I'm so Happy i stumbled upon this channel. You are awesome!
You also don't realize how quite the world could be until you get tinitus and loose that quiet forever.
Protect your ears ;)
Didnt realise i had tinitus till i experienced ambient silence. That was shit.
I've had it for as long as I can remember, so I don't know what I'm missing
@@anonimase4315 same
Yeah same I've always thought silence was that ringing my whole life
Damn, I wish they thought of anechoic chamber like homes in the movie.
I love the movie A Quiet Place, I also love the videos you made that refer to sound. This one, the Thunderclap, and Black Bolt. I've been too a bunch of metal concerts and you're right those are loud.
12:52 Kyle, we don't live on the same continent. We're more than 30 km away. And I hear you perfectly
Not sure if this has been mentioned yet, but here are a few quotes that may handle elevation and front/back localizations.
The shape of the outer ear (pinna) that transforms the frequency characteristic of incoming sound. In terms of directional hearing it is thought that sounds coming from above lead to a different head transfer function than sounds from below. This means that localization can only be accomplished when the sound has a particular familiar characteristic that is slightly disturbed in the frequency domain when encountered at different angles of elevation (Hofman & Van Opstal, 2003).
Front-back localization is thought to be mediated by processes similarly to elevation cues. Spectral modifications work like filters and are derived from the reflections of sound caused by the shape and size of the head, neck, shoulders, torso, and especially, by the pinnae (Zhang & Hartmann, 2010).
Depends on the person listening really, to me it would sound like an endless ringing since i have Tinnitus...wish i didn't thought, makes falling asleep allot harder unless i have some white noise...or an awesome podcast that doesn't use jumpscares like Because Science so i can dooze off, keep the awesome work Kyle.
your voice sounded so good while you were in that room. it was so much more peaceful to listen to, it actually made me feel noticeably calmer and more relaxed :)
I Love the sense of humor of this channel. 2nd video ive seen so far. stuff i watch in the middle of the night when i cant sleep haha

“Adorable little hooty bois” I love it 😂
I was hoping for an ASMR Because Science.
Nin10 honestly what is the appeal with that shit
some sounds give some people a tingling sensation like having a lover whisper into your ears, their breath tickling your skin...or, if you're closing your eyes, the sounds of a time long ago to your parents in the kitchen cooking something, and it strangely triggers your sense of smell and you smell the food while listening to the pots and pans, the sizzling, etc. ...it's kinda like that. =/
Mike Hunt I've had times when I felt tingles when people whispered into my ears in a quiet environment.
Obviously
my thoughts exactly :D
Mat pat shouted you out on film theory
Nathan Sim I think mat pat has mentioned because science a few times
Thank you for all the fascinating information...riveting,plus big lols
You're channel is such a awesome place. I love the humor and the science. I mean just look at your Mini-Thor hair. It has to be creating the science.
HOOTIE BOYS
Smarter Every day have a really interesting video about the shape of the human ear and the effect it has on dimensional positioning of the human hearing.
I've helped build anechoic chambers for research. Ther'e also a real electrical problem, fans and light bulbs tend to make 60 cycle noise that is easily picked up by instruments you might use. *Sleeping* in one of these, which I've done, can be disturbing as you drop off, but also tends to lead to oversleeping.
For me to like a CZcams channel, I usually see about 5 episodes. Kyle, it only took me one episode to hit the subscribe button. Your personality is awesome, bro :)
But you don't actually want to be in the quietest place on Earth, you want to be in the loudest place on Earth so you can act normally and not be heard by the monsters as you'll be overpowered sound-wise by the natural noises :o
The God Emperor this vid isn't about the movie the quiet place
@@christiandejesus8789 ya think?
But they would also always be close to your location as they are attracted to sound
Are we sure about that? They sure seemed to not care about the waterfall far as we saw.
The God Emperor. Actually, that might not work because for this to work you need sound cloaking, in which where one sound is louder that another that vibrate at the same frequencies, and if you were to act normally, depending on the sound, you could still be detectable with how precise the hearing of the monsters braised on the movie because the different frequencies, and all your body functions of actions might have different frequencies than one another, enough to not be cloaked
-wow I just wasted way to much time on this-
Does the db scale go down forever, or is absolute zero sound some finite number?
Lazor basically, is it like temperature where 0 K is well defined but impossible, or does it go off to negative infinity?
The smallest volume possible may be the smallest unit of energy moving a single particle, or something like that.
How about google that question instead of asking random people in a youtube comment?
Broken Wave I did. I couldn't find an answer.
considering sound is effectively kinetic energy in air, and having 0 kinetic energy would mean having no sound at al,. I guess an empty space at 0 K would probably also be absolute 0 for sound

7:30 I was just waiting for an anechoic chamber to show up. Thumbs up earned!
You: *tells us to put on headphones*
also you, later: *makes chewing and other mouth noises that drive people crazy*
Well played. You win this round..
Just a quick thought, wouldn't the use of sound masking be just as effective as making your home sound proof? If you could generate pink or white noise that is played in all directions which is at higher decibel levels than regular household activities, it would theoretically make the audible perception of said activities impossible to anyone or anything that was not close enough! It would be like creating an audible barrier around any given area! Think about trying to hear the conversation between two people three rows in front of you at a concert, it's impossible unless you're close enough.
That's a really good idea but wouldn't work in the context of the movie as they're smart enough to figure out something is up. It would lead to everyone of them in the area sticking around until they made it stop.
But what if you made, say, an entire city as loud as possible? then one family making noise would be hard to find.
the thing is that it couldn't even get that far, a species that rellies entirely on one single sense could never hope to defeat a species that is perfectly capable of disrupting that sense.
I've seen various youtubers going to such chambers but your video was my favourite
BAM -- KH
Vsauce Michael here
Was in a room like that. The place tested sound emissions for new vehicles. it was a 50' x 50' room and it is very crazy thing you don't realize how much sound there is in our lives till there is virtually no sound. the coolest thing about the place was that one of engineers that worked there put me in the opposite corner than he was in faced each other and he whispered... it was like he was right next to me because of all the echoes from his voice were gone and I just heard the straight sound waves from his voice. it was truly an amazing thing to witness, but I did see how it could be very unsettling.
Congrats bro...i like your videos....teaching with more leisure and casual way 🙌
I know it's figured out at the end of the movie that a certain sound wave will hurt the monsters but i dont think they didn't give Humanity enough credit we would have easily figured out that these creatures have God like hearing and we would have made a device that spits out sound constantly to distract damage or make the monsters run away. The collective Humanity would have figured this out. The only way I can see this not happening if they literally wiped us out overnight and in the movie It's implied that it took some time for the majority of humanity to be killed
I agree.
Spoiler warning please
So the only survivors would be people in mosh pits 🤘🏻😎🤘🏻
i have two words for that.
automatic rifles.
if you ever had the displeasure of being anywhere near one you know why no species tha trelies on sound could ever best humanity, not with the weapons we use in war.
to give you some perspective we have been able to create weapons that emit pressure waves so powerful that they could be measured after circling the earth twice.

“A Quiet Place” is actually an amazing movie. Also, for a movie about silence it’s awfully loud.
I've been in that anechoic chamber before on a tour. It was interesting to say the least. They didn't have the plywood on the floor when I was in there though, that adds a point of reflection.

Can you talk about how slip space works from halo
Thanks to you you I watched "A quiet Place" yesterday.
I havn't heard of this movie til you mentioned it.
I was impressed, indeed! What a well-made film!
And you were at Orfield with the wood floor in. When they take that out it's a spring floor with even more sound wedges below.
Kyle, the Human ear is designed to understand verticality, the upper and lower lobe are designed to reflect sounds above and below into the ear at different wavelengths and the ear can tell the difference.
Wardonis life noggin?
If someone wanted to escape super sensitive aliens they could just go live in a busy city. That way they could camouflage themselves with sound. Also, that way they would have self defence. Because of the noise from the city the aliens would probably become deaf. Maybe not fully deaf, but at least their hearing would get a lot closer to that of a human and they couldnt find you. In the worst case for them, they might even die - that depends on their sensitivity.
Vedran Jakelic yeah but if we’re talking in the concept of the movie, only few people were left on earth. Thus, not any big cities
It's amazing how echos in a room distort sound. Sound deadening walls help; but the best quality hands down is from miking close (10 to 20 in) to every musical instrument. That means booms, cables, etc. EVERYWHERE, yet with a dozen or more instruments you hear every note from everybody all the time. eerie, almost, but GREAT. Type in "youtube/orchestral/active/NEETs", it's a mind blowing improvement even with crappy built-in speakers.
This is my favorite channel to go to about science (duh because well science) and it's about stuff that may seem interesting as well
of course if the monster got into your silent house it would find you much easier.
how can that be the quietest place I would imagine the millions of dust mites to be very talkative
Yes, they talk to me ALL THE TIME, dust mites are very opinionated and sometimes even a little rude.
@@ryanhansen9779 maybe try doubling your meds
@@pulseweld haha. Have a great Tuesday.
Atop Mount Evans in Colorado on a calm day it was quiet enough for me to hear my heart beat which I found fascinating.
Things like this that have higher hearing thresholds are easier to distract with *_sound traps_* like automated percussion machines rigged to go off when tripped by some trigger or multiple triggers or you know, whatever works.
Also, higher hearing thresholds lead to issues with certain equilibrium problems like vertigo. Loud, consistent sounds assailing the ears all at once can lead to dizziness and even to vertigo. I'd be attempting to use this higher hearing threshold against them.
On the subject on surviving against aliens, wouldn't it be easier (both to do and to live in) to go to a place where a lot of noise is made naturally (like a river)? If you did so, then the aliens would know to ignore any noises coming from that area (unless they are complete idiots who will continue to go there no matter what, but at that point, how are they even a threat?), and you would be able to make as much noise as you want.
This would be way easier than trying to find a really quiet place and trying to maintain a really quiet lifestyle.
Hank Whittaker have you seen the movie? They do this at one point, (go near a large waterfall in order to communicate) I don't know why they didn't build their shelter near it, but the concept was there. And it did work.
Nathan Cochran Actually, no, I haven't seen "A Quiet Place". Would you recommend it?
@@Sunny_Haven I would. But I do have 3 warnings. 1.) there are maybe 15-20 lines spoken outloud in the movie. 2.) most of the movie is subtitled sign language because a better half of the movie is shot from the perspective of a deaf girl (who is actually deaf so A+ for casting) 3.) sound is the most important part of this movie so I would recommend good headphones if applicable.
I think it’s because they’d get so used to the waterfall that they wouldn’t be able to hear the aliens if they did happen to be wandering nearby. That or get used to a normal lifestyle up to the point they’d forget about being quiet when scavenging for food. Also, the spray from the waterfall would dampen the house and cause it to deteriorate.
The movie was really dumb imo. It would take humanity 5 seconds to find a counter measure. If it hunts by sound blow out its ear drums invasion over. I did like them looking at sign language as effective, since some of my family is deaf it was a neat idea and should be more explored in scifi and horror films.

Actually, at -80db it would not be 100 times quieter. The difference in sound 1 and sound 2 is measured logarithmically. So if we assume we heard a 1db sound from you, the difference wouldn't be 100 times quieter, it would be 100 MILLION (Dr. Evil Pinky) times quieter.
Update for critics: Specifically talking about the power pain of the decibels btw, -80db has a power gain of 1E-8 and 1db has a power gain of about ~1. ie 1 and 8 zero difference between the two. I chose 1db as a comparison to play up the 100 to 100 million, and making an observational joke on the over analytic nature of the show in general using the fact that decibels are logarithmic.
Sean Peery I think you missed his point on "100x quieter".
actually when a sound increases by 10 Db, the 'loudness' doubles. So -80 would be 2^8 or 256 times quieter
100x quieter because its 100x farther is also wrong. because sound waves follow the inverse square law. so a sound you hear 1m away from you, if you move 100m away from that sound source, it will actually sound 10000x quieter (ignoring echo and fluid dynamics)
Danilo Oliviera sure the amplitude or intensity would be 10000 times lower, but the volume we hear is not directly proportion to the intensity of the sound. We hear 'Loudness' Logarithmicly
ACTUALLY, the point he was making is the actual physical sound he was making while imitating a shrimp would be ~100x quieter, and then put into that scenario.
I came up with a design for the quietest place on Earth (and possibly even some places in space): You get two, giant, hollow, metal balls, one smaller than the other, which you put inside the bigger one. The smaller one has permanent magnets attached all around it and the bigger one has electromagnets attached all around it (or they are just made of magnets, as long as the balls are airtight) Both balls have sealable doors. You walk into the bigger one and then the smaller one, then you close and seal the doors. From outside, someone starts up the electromagnets powerful enough to make the inner ball levitate inside the bigger one in every direction, so they no longer touch each other. Finally, someone starts a vacuum pump that's connected to the bigger ball and sucks out all the air in between each ball. There would be literally no way for outside sound to be heard in the smaller ball because there would be no matter for it to travel there through. As for inside sound, you could put those foam panels from the video in the smaller ball. Tada, ultimate quietness. (Note: this doesn't really take into account the specific needs for a human to live in this machine.)
Anechoic chambers work in an amazing way. The longer wavelengths with lower energy get absorbed into the cloth foam pieces whereas the shorter higher-energy wavelengths are destructively reverberated as they approach the wall. All of which deaden any sound perceivable by the human ear.
Also, hearing is the only sense that is 100% mechanical in nature. Sound makes bones move which make hairs move which trigger nerve response.
@BecauseScience Since the aliens sound threshold is so low, wouldn't average sounds for us hurt their ears like if we yelled through a megaphone to bust their drums or does it depend on their ear structure?
Does the energy sword in halo work similar to that of a lightsaber or completely different ?
I didn’t realize that there was an anechoic chamber here In Minneapolis. I have heard from others who have been inside other chambers that spending too much time can be maddening with nothing but the sounds of your body working. I think it likely depends on the person, some people love to be in quiet places and for others they hate it.
It’s not echoing.. echoing is sound traveling in the direction it comes from the source. You’re referring reverberation. The sound is redirected in a process known as reverb.
The way you described the quiet in that room and the way it amplified little noises sounds like something that's happened to me in the past. I would be sitting in a quiet room (typically the bathroom) at night and the quiet of the room made my ears start to (for lack of a better term) 'ring' and I would hear all the little noises like me bending my elbow or moving my jaw would.
i hear ...no pun, some people don't have that ever present ringing in their ears, i envy them.
Since those aliens hear way better than us, instead of being quiet, wouldn’t it make sense to make the loudest noise possible to explode their super eardrums?
Yeah those things must be baby thin.
Unless...
What if those ears are made of a super resillent material ?
teacher: ok class whats the sound do you hear in churches...
special ed kid: 10:14
I immediately think of sitting out in the woods sitting in a tree stand during a deer hunt. With no wind, it’s so quiet you could hear an ant fart at 100 yards.
Ok science girls and bois, here's my question. Because the aliens are so sesitive to noise, would there be a decible point where the survivors could weaponize the sound against them? If I'm going into spoilery territory feel free to tell to jus go watch thw movie.
they could have some type of noise damping technology to prevent this i mean they are aliens
Jess_Marie_G You're close to right, I can't think of anything else to say without getting into spoilers.
Definitely worth watching the movie for that answer. And because it's actually fantastic. I didn't think a movie with almost solely sign language would be so great. I watched the movie and I still had to do a bit of figuring out and looking. Let me know if you have any questions after you watch it!
I'd think they'd hate gunfire even if the shooter wasn't very good. 167 dB 5.56mm rifle muzzle blasts hurt our ears. A 35mm chain gun at 188 dB would be to their special ears what looking at the Sun through a rifle scope is to our eyes: permanently damaging.
Given a parabolic reflector to focus it, a stereo could become a very effective disabling weapon, but others would find it from other angles.
A radio-controlled car with an iPod taped to it could be used to lure them into a warehouse with a box of fireworks in it, and once they were inside an electric igniter setting off the display would be devastating.

Well, *unless* you're trying to use it against a tank zombie or an alien or a gang of child-molesters or something, never light a major outdoor firework display in a confined space.
I'm pretty sure that it's possible for them to also have a higher tolerance to loud sounds than us as well, though it's unlikely. I considered that as well.
How have I only just now stumbled across this beautiful science man??
my room is covered in posters and soundproofing so it has great acoustics for recording. i have to put music on when i sleep a lot of the time because i can actually hear my heart beat and all sorts of other things happening and it's so unsettling
Quietest place on earth:
Outer space.
Oh wait...
