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

[@hendrong]

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.

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.

[@drizzlingrose]

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?

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

[@barrybend7189]

Cj Rainbolt actually in complete silence our brains literally imagine sounds much like someone getting phantom pains from losing an appendage.

[@danilooliveira6580]

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.

[@EGeorgev]

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.

[@loganballard1224]

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.

[@humblesoldier5474]

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.

[@wocxdid8068]

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

[@cheetahrat88]

Watchmiker that's seriously amazing.

[@bernat_CustardCream]

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.

[@josephmorse3089]

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.

Human voices can hit incredible pitches in the right circumstances, and it's a build in defense mechanism we still use.

[@WisdomCritFail]

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.

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.

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.

[@Thane36425]

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?

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.

[@windhelmguard5295]

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.

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).

[@very_clever_name1636]

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-

[@ProducerJS]

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.

[@BadGladeCrazy]

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.

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.

EMBRACE IT -- KH

[@thebagelbomb]

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.)

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.

[@seanpeery7780]

15:23 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.

[@joshsnyder4868]

Sean Peery I think you missed his point on "100x quieter".

[@MrJimmyd500]

actually when a sound increases by 10 Db, the 'loudness' doubles. So -80 would be 2^8 or 256 times quieter

[@danilooliveira6580]

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)

[@MrJimmyd500]

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

[@joshsnyder4868]

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.

[@SeantheBawse]

@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?

[@vertex546]

Mom worked 2-3 jobs when I was growing up so she was always sleeping when she was home. In order for her to get some sleep so we could eat, I grew up trying to be as quiet as I could be when she was napping. After a while, you really do start to get used to hearing your own heartbeat, or your joints grinding.

[@brandoncain4419]

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.

[@andrewjames4346]

What's quieter? A vacume like space or an anechoic chamber and how would we measure that?

[@theldraspneumonoultramicro405]

the vacume of space wins hands down because there is no medium for sound to travel thru, if you where able to percieve light as sound, such as radiowaves for example, (you can convert light into information and that information into sound) then it would be very loud and it would sound absolutely horrifying. here is how our planets and the sun sounds like: kzbin.info/www/bejne/f4KvZmabhpWWhKM (actualy, there is, but the density is so extremly low that it may just as well not even be there at all)

[@drops2cents260]

@A Moore > What's quieter? A vacume like space or an anechoic chamber Err... you actually mixed up two different things there. In an anechoic chamber, sound can still be produced and transmitted by pressure waves, i.e. air molecules pushing each other and thus transmitting said pressure waves. It's just that many of those molecules and pressure waves are "caught" by the material and shape of the wall panels in an anechoic chamber and thus can't travel around very much. So while you don't hear (much) an echo in these chambers, you still _will_ hear sounds, although they would sound strangely muffled because they lack the echo we usually hear and thus have grown accustomed to. Space vacuum is a complete different story, because it is so empty that there aren't enough molecules to transmit sound by pushing each other, and thus there's literally "nothing there" to transmit pressure waves. So you _can_ make sounds in vacuum, but they just aren't able to _propagate_ because there's no "means of transport" for sounds. And that's why in space, literally no one can hear you scream.

[@drops2cents260]

@Paul Hernandez No, dude. Actually, it's really dumb to only ridicule such a questions as being "dumb" without also providing an answer. Because if the question really is so "dumb", you shouldn't have had any problems to give a correct answer and an explanation, innit?

[@Rhekon]

How does absolute pitch work? How can some people be tone deaf and others can readily identify pitches from whatever culture their music belongs to? Also how loud is the sound of a TV turning on while muted?

[@barrybend7189]

William White brain glitch. Nuff said.

[@Sheol02]

The TV question - it depends on a particular TV. Also, muting it doesn't necessarily does anything to the turning on sound. If it does, then there won't be any sound except for the sounds electronics make. It's like if you don't speak, you're "muted", but it doesn't cancel out all the other sounds you're making.

[@BobBobson]

Tone deaf. Not death. And it's the same as vision. Some people see the whole world as a blur without corrective lenses, others have amazing eyesight. It's all about the specific genetic mutations that created you. Humans exist on a spectrum. Height, weight, speed, strength, vision, hearing, etc. They function on a higher level of signal processing. It's not that they get extra information, they just process it differently. For someone with AP identifying tones is like identifying colors for most of us. Once they can put some sort of identifier to the tone (A-sharp) they can identify it easily, or reproduce it on an instrument, like how you can see the color blue, say it's blue, or point out the blue spot on the color wheel.

[@Rhekon]

Bob Bobson corrected. I usually don't make mistakes like that lmao

[@adamloos1388]

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.

[@KiithnarasAshaa]

Fun story: The complex shapes of your ear pinnae actually help localize the verticality of sounds for people. This is clearly less than desirable for avian creatures, as those pinnae would create drag, catch all the sound of the wind rushing past, and create sound of their own as they fly through the air. This is also why mammals with articulating ears, e.g. dogs and horses, change the angles of their relatively simple ear shapes as well as tilt their heads when hearing sounds.

[@upwiggins]

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

[@saablazer1658]

I agree.

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.

When I work in the Patient Office, one of my jobs was to file papers into completed patient applications. All of these files were in shelves stacked 7 feet high and at least a hundred feet long and they were on both sides of me. If the person next to you said something you could not hear them. If they yelled at you may be able to hear them, and if you did it sounded like Daffy Duck whispering. To communicate we carried note pads and wrote notes, learned some sign language, tap shoulder to get attention or stomp our feet. We could feel the vibrations in the floor. The admin people would use air horn to signal for breaks, lunch, closing time and emergencies. This sounded like a truck horn sounded a couple of mile away.

[@HoneyBoom]

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

[@vedranjakelic8880]

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.

[@TheVooDooCritic]

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

[@green0one]

of course if the monster got into your silent house it would find you much easier.

[@MrWardonis]

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.

[@rudyerickson3830]

[@davalious5107]

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.

[@jeffgrencik7213]

i hear ...no pun, some people don't have that ever present ringing in their ears, i envy them.

[@JammyBriton]

Everything emits and/or reflects infrared rays, some equipment can pick these up to form an image

[@OddBunsen]

The reason you feel that a stove is hot without touching it is because of a type of light we can't see called 'infrared'. That light is what heat vision cameras see.

Thank you for all the fascinating information...riveting,plus big lols

[@AmyraCarter]

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.

[@pulseweld]

how can that be the quietest place I would imagine the millions of dust mites to be very talkative

[@jimhsan1]

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.

[@3Bixby]

How have I only just now stumbled across this beautiful science man??

[@FlagCutie]

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.

[@tonyman1106]

they could have some type of noise damping technology to prevent this i mean they are aliens

[@idahocartwrights]

Jess_Marie_G You're close to right, I can't think of anything else to say without getting into spoilers.

[@Tylerohwhat]

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!

[@Sableagle]

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. Never light a major outdoor firework display in a confined space. kzbin.info/www/bejne/r6axZaufp9ubfrs 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.

[@RonnocFroop]

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.

[@Sunny_Haven]

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.

[@Anurahm_Kycor]

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.

[@Sunny_Haven]

Nathan Cochran Actually, no, I haven't seen "A Quiet Place". Would you recommend it?

[@Anurahm_Kycor]

@@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.

[@UnforgivingDeath]

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.

[@ck7512]

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.
