If a tree falls in the forest and nobody is there to hear it, does it make a sound?
As far as I understand it SOUND has multiple usages. 1) The action or thing that creates audible sound waves putting it out into the world 2) The sense of hearing that noise and transferring it into a recognizable 'sound'.
So yes it makes a sound (1) .. shame no one heard it (2).
It makes a sound. Isn't that just logic? If we were to video tape this on mute or something and watched it later would it count?
OKAY LOOK, 7TH GRADE BIOLOGY TEACHER. The definition of a sound is SO NOT when the sound wave hits the eardrum and is registered by the brain as a sound. IT MAKES A SOUND BECAUSE IF SOMEONE WERE TO BE IN THAT FOREST THEY WOULD HEAR IT. Sorry. Still pissed because I missed that on a test.
Idk, I remember watching a show that explained someone or something has to be there observing the tree falling to actually be able to hear the sound produced by the tree falling..
Ironic because I was just having a discussion with my sister about this
As far as I'm concerned, if I didn't see it or hear it, it didn't happen. That's how I get through life.
Coincidentally, that's also how I get through presidential elections.
No durr it makes a sound
Sound is the interpretation of waves through the air by humans and other beings. If no one is there to hear it, it cannot be classified as noise.
I can't believe this many people are wrong; the answer is NO! I learned this in physics
Unless it hits a mime!!!
if someone posts a dumb question will it get more votes and comments than a real one
Lol. Geez. Ppl. All this is now, is you are all saying exactly the same things over and Over and over and over nd ver and Over and over and over
That's like saying no sound is made when any object falls, or lightning strikes, or volcano erupts, or river runs, just because a human isn't there to hear it. Wow.
For God's sake, people, OF COURSE IT DOES!
There are sound waves produced. It makes a sound.
If a tree falls in the forest does anyone really care?
My father, who was born in Louisiana 1920, was punished in first grade for arguing with a teacher when she said the answer was "no."
everybody should stop arguing because nobody will ever know.
Uhhh I'm pretty sure that scientific instruments can detect sound waves and no human needs to be there.
Well if it doesn't, then I guess before animals came around there was no such thing as sound.
I can't believe this debate is still going on.
Now that's a lot of blue
If a bear goes poo poo in the woods, does it still stink? Riddle me that America.
No because sound is a conception of the mind and if nobody perceives it to be heard then its not a sound.
Sound is a physical thing. It has nothing to do with the mind.
Ah that is where you are wrong, waves are a physical thing sound is perceived in the mind when the eardrums receive the waves
The field of audiology would disagree.
The field of physics and psychology would disagree
There are probably animals in the woods hearing this sound so yes it does. To think just because humans might not hear the tree fall does not mean it doesn't make a sound, an other arrogant human misconception.
You think physics defines waves as perceived by humans?
Physics says that sound is in waves and psychology says that the mind perceives sound.
And that is not the question, no one is around.
Psychology does not define sound as only perceived.
It defines sound as a wave that is received by the ear and then into the cerebral cortex to be perceived to what the sound was.
Sound waves stimulate the eardrum, which stimulates the bones on the ear to vibrate.This is picked up by tiny hair cells in the cochlea which stimulates your auditory nerve that sends a signal to your brain that a sound is present. Your brain identifies the sound.The brain doesn't create the sound.
Quantum mechanics humanity's best description of the physical world says no if no consciousness is around to experience the tree falling and the corresponding sound it doesn't exist.
No, because quantum mechanics applies to quantum scales.
Yes. Makes a crkkk bkkk sound and no one will hear it. Easy as that.
Dumbest. Question. Ever.
If a tree falls in the forest, and nobody hears it, does a hipster record it as his ringtone?
Just got home from physics; to confirm what most of us already know, if a tree falls in a forest and nobody is their to hear it, it still produces a sound.
Physics laws are part of our interpretation of reality. They aren't independent from the mind; take the refinements performed from Newtonian to quantum physics as evidence. One needs an observer to give meaning to reality.
Yes, it does make a sound, regardless if anyone is there to hear it
Hey guys I'm baaaaaack lol
RJ was looking for you awhile ago.
Whoops lol. I was a little late. It's PugS lol. Not pigs.
A NOISE has to be HEARD in order to be considered a SOUND. Dumb a$$e$
Actually, sound is vibrations that travel through the air even with out a person present. P.S. Your the A$$
one time I peed in the woods no one was around, did anyone see it
Sound is the perception of the mind. There is no sound if a person/animal is not around to translate the air waves and interpret them as sound. So if a tree falls in the woods with no one around, it does not make a sound.
Sound existed on earth long before anyone to hear it. Nature is not silent.
Sound is a pressure wave in a conductive medium such as air or water. No observer is required for it to exist.
Basic physics people.
Its a pressure wave picked up by peoples ears.
Pressure wave that can be picked up by people's ears.
I disagree. Sound is sound regardless of animal interpretation Pops!
Noise by definition audio heard
Sound, not noise
I know they're usually synonymous, but details count here.
To those who discount the need for an observer: We must all be surrounded by an infinite amount of various sensations that we don't know about because we only have five senses. That tree is making "glorbles"! I just can't "glorf" it!
And you disprove your own point yet again.
The tree is still producing "Glorbles" regardless of your ability to perceive it.
We can't perceive Radiation. You going to say those don't exist?
Mit: Once again, the question was not,
"Was a vibratory wave produced?" Here's a radiation question for you: What color are gamma waves?
Sound is a wave.
Sound is indeed a (longitudinal) wave.
If a tree falls on Glenn beck in the forest, and no one is there to see it, would it still be funny?
Hahaha... Hell yes!!
So the sound produced by elephants that are below the range of human hearing isn't a sound? Sounds that birds make that are above the range of human hearing aren't sounds?
Simple science people. Give it a try, actual reality can be fun!
1 a : a particular auditory impression : tone
b : the sensation perceived by the sense of hearing
c : mechanical radiant energy that is transmitted by longitudinal pressure waves in a material medium (as air) and is the objective cause of hearing
So, no, sound is not just "the wave". An observer is required. All if the definitions (copied from Websters) involve hearing.
Um..... C) proves that sound exists independent of the human auditory system.
But that doesn't mean that they require hearing.
So a device that fires sound waves at a glass can only break it if someone is in the room?
Great logic. *face palm*
No, Rand, that's just a pressure wave, which is what sound is. Oh, wait...
No, c) does not prove that. It still references an objective cause of HEARING.
Of course the glass breaks. Tony didn't ask if energy was produced (yes) but if sound was produced (no). At least come up with some good objections.
C doesn't require a sound to be heard in order to exist, though.
C) states that its a cause of hearing, but nowhere in that definition is the observer required.
If you throw a rock at me, it will cause a lawsuit. The lawsuit wasn't necessary for you to throw the rock.
You could also use the scientific definition. Which doesn't need a receptor.
Sound, longitudinal wave phenomenon that consists of successive compressions and rarefractions of the medium through which it travels.
"It's just a pressure wave until you hear it." -many people
"Oh my god! What do you think sound is? It's a freaking pressure wave repeated at an interval!" -me
Actually sound is perceived by the observer. Without a mind there is no sound. Yes, I know that this depends upon your definition, but in my book a pressure wave by itself is not sound.
Then your book is wrong.
lfb. Give critical thinking and science a try sometime.
Rand: I've likely done more critical thinking in an afternoon than many have in their life. I'd "one up" the tree/sound discussion and say that the universe is based on perception. Read Bishop Berkeley and apply his thoughts to the Einstein-Podolsky-Rosen paper. Critical enough for ya?
Critical, but I disagree. Although I do agree with the theory that our existence is the reason that the universe can support life. Otherwise, we wouldn't be alive to ask why.
You're free to disagree (I don't think that it's our existence either, but I see your point), or even disagree with the "sound" question. But to suggest that I'm not thinking critically is presumptuous nonsense. The "no" answer to this question was one that I have after much critical thought.
And after seeing so many posts on this, I can see why you think that. In the end, it comes down to how you define sound: a physical phenomenon or a sensation.
Observation is not necessary for existence.
For example my car exists right now, even though I am not looking directly at it.
1111: Agreed, it depends on your definition.
If someone's deaf and can't hear doesn't mean that there is no noise going on around them.
According to quantum mechanics and the observer problem the correct answer is actually no.
Quantum mechanic apply ONLY to quantum scales.
And most things are made of things based in the quantum...could that still not be relevant?
Idk, im tired i dnt feel like thinking
Wasteland, because molecules in a macro scale situation constantly interact with other molecules, the same rules no longer apply.
Yes. By interacting with other particles, superposition is eliminated.
Does a bear poop in the woods?
This has been answered many times. The short answer is no.
Not the bear by my brother's house. It poops on his deck.
No. It is just a series of pressure waves untill it is detected by and auditory organ. Only then is it sound.
You really need to read this thread. That all depends on what definition off sound you use.
Yea, not a fan of the auditory organ requirement.
Neither is the field of audiology
If Richard Simmons is alone the woods is he still annoying? Of course.
Well of course it does!I mean seriously just because someone didnt HEAR it doesn't mean that it DIDN'T produce sound.like if u have ur headphones/earbuds on a really low volume so that u can only hear it when it's in ur ear. U take it out, put it back in. It still made sound wether audible or not.
I said no at first, but after reading some of the discussion and doing some wiki research, I have concluded that it is a yes. Sound still happens because it is the mechanical property of vibration. That tree is going to make the air vibrate along with itself. So sound definitely occurs.
Hahaha "wiki research"...that's like saying "chess athleticism."
But is vibrating air "sound" if it is not perceived? Isn't it just vibrating air? Otherwise you'd have to say that there is "sound" even if air is vibrating at an inaudible frequency.
1000+ comments..... Wow
Does a bear shit in th woods? yes it does.
Not if its in a zoo...
Not if its a city bear. We have plenty of those here.
thought sound was just the vibration... not the reception of the vibration... so yeah, if the tree fell and hit the ground, it made a sound.... some vibrations are not able to be picked up by a brain, but it still made a sound regardless... perception does not matter
Perception is the key. Tony isn't asking "did the air vibrate" but "was there a sound?" Sound requires perception by a mind.
