Oh jeeze, this is one of the most confusing Youtube videos I've ever seen, that being said, I didn't think that much math went into sound, as a matter of fact, I didn't think that much of sound at all. If splitting sounds in have creates different notes and such, I wonder if the same can be said about human speech, and as well as if a human can sound like an instrument. Hmm... it also makes me wonder about bird calls...
I had to watch it twice. It makes more sense the second time around. Either way it is very interesting. Great Post Joshua! Have you ever pulled different size rubber bands and plucked them? It is easy to imagine then.
well she's ridiculously smart...but from what I understood from the video, the sequence of events that she was describing of how the sound gets to our ears, at around 3:00-3:50, it kind of reminded me of arithmentic sequences of how each "wave of sound" (I guess you could say) has a distinct pattern of how one vibration amplifies the next sequences of vibrations through the hairs of our ears.... I think what she was saying is that our ears can recognize distinctive sounds because of the level of vibrations that are created at the different tensions but when they are all overlapping they each wave length gets recognized by our brain and makes one single note.... I tried haha this is pretty complicated. (This is what I meant by arithmetic sequences: http://www.mathguide.com/lessons/SequenceArithmetic.html )
Jessica Revolorio pd6: Wow, that was a lot to take in! But I came to understand that the ear works in such a magnifisant way! It is a very delicate and detailed senory organ. Sound travels through the air as air pressure makes vibrations. The whole process allows the brain to translate the signals to be able to hear, who would have ever thought. And I think its amazing how time travels in 340 meters per seconds and it allows the ear to be capable of putting every single vibration to make it possible to hear one sound.
Have you ever thought of how you can tell where a noise comes from? For example, if you close your eyes and someone is off to the left of you and speaking, how does your brain know the noise is coming from the left? both ears heat the noise, so how does your brain know?
this is very cool but its very looooooooong video! lol Its so fascinating to see how we hear relates to math. i didn't even think math had anything to do with the way we hear things! The strings part in the beginning kind of remind me of a line on a graph or like a lab we did in physics. wow, everything is connected in some way or another. weirddddddd. Every time she made the string on the viola smaller the string made a different noise each time.
dang musta took her a long time to do all this. someone needa a boyfriend. BUT ANYWAYS, its interesting how a simple thing like hearing can be broken down into many COMPLICATED steps, and can be eventually understood the systematics that go into how your brain translates the sound. like Joshua said, i dont think that much math goes into hearing, she just made it seem that way, like you can do with alomst anything.- destiny
To respond to the second question Mr. Frank posted, I think that the reason we can tell where a noise is coming from even if we did not see the source of it,depends on wherever the source of the noise is relative to us. For example, if your friend is standing to your side then the noise they make will seem louder on the ear of that side. Generally, human ears are curved forward so if a noise comes from behind you, then you will hear it softer as opposed to if it was directly infront of you, in which case it would seem louder.
-A cool fact: If you push your ear so that the opening is pointing toward the source of noise, then you will hear it louder.
-Apparently, some animals like wolves, have muscles that can move their ears, this is used to help hear prey.
Great post Dan. I have a question for you (or anybody). If you think it is just intensity of sound that allows you to determine the location of a sound (left or right), how would your brain determine distance away from you? In other words, if you close your eyes and have someone talking 25 feet behind you and to the right, how can you brain tell that they are to the right, and far away?
To answer Mr. Frank's question, your brain can tell that the person talking is far away and to the right because of the sound waves, it's like what Dan said about wolves and other animals moving their ears in the direction the sound is coming from.
I watched this video three times and still dont fully understand whatever she is talking about... she must go to private school. anyways i think that she was saying that we hear soundwaves in pitches. the higher the pitch the longer the sound wave is and when the soundwave enters our ears and it notices that it is longer it tells the brain that it is a higher pitch
Woah, that girl is extremely creative! I play the violin too so it was really cool to realize when i pluck my string, as fast as i pluck it in would duplicate the vibration. Another thing i found interesting was how the vibrations of the sound, are related to the graphs we do everyday in class. To answer Mr. Franks question I think that i agree with Aleena, your brain can tell if the sound is far away or close up, which remind me of the graphs we do everyday.
Very cool guys. I agree it has to do with the sound waves that allows us to tell where a sound is coming from, but what it is about the sound wave? Is it the amplitude (loudness that is), is it that frequency (pitch), is it time???
This video is so confusing ! Sound waves help you tell where a person is standing. If a person is standing to the left to you and is at a certain distance, it is easier to to hear them. But the farther they are away, it becomes harder but, with sound waves, it makes it easier.
A violin has four strings. The harder you pluck the string or play the instrument, the longer the sound of the note will last. So, even if you use different objects, there is always sound. It always travels by sound waves and vibrations and you always have to count the beats in order to know how fast or slow one person is playing.
Am I the only one who thinks when she's speaking, she kind of sounds weird?? Oh well, maybe it's because of my hearing.
I watched this video 4 times and I still don't understand it. The way she's explaining it is very odd, I don't know much about sounds and all that but this video isn't helping. What the video is stating is totally different from what I learned in middle school about sounds and hearing. I agree with Theresa, the farther a sound is from the ear, the lower it is, the closer it is to your ear, the louder it is. We are able to tell which side a sound is coming from depending on how close it is to us. I think Dan's example is a simple, yet good one. That's simply what I think about sounds, I don't see what Math has to do with it!!
Mr. Frank i think its the pitch. it depends how low or high the pitch is. if the pitch is high then your ears will automatically sense the direction the sound is coming from, i guess the vibrations also have a part of it. the more vibrations the sound makes the faster it gets to the person or the faster it travels.i also thought it was interesting that we only hear on pitch even thou there's many playing at once, like how music sounds better as a whole. i didn't get the math part but it does tie in with the graphs really interesting Mr. Frank ill have to watch it again

ReplyDeleteI believe that it is the amplitude that allows us to locate where the sound is coming from because as you get closer to a wound it gets louder.

Joy what do you mean this is different from what you learned in middle school. How so is it different and which ways it is similar?
ReplyDeleteAlso, look again for the math. It is definitely in there! The rest of the semester we will be studying functions that represent sound and light waves.
Who hasn't? I've only done it with rubber bands though... It's hard making music with it...
