- With exciting 3-D animation and a dramatic classical sound track, this 7-min. video takes us on a trip through the ear to vividly explain how we hear. Auditory Transduction is definitely best of breed on the topic. Brandon Pletsch has given permission to 3M to post this video on our web site and CZcams.

Almost everyone's talking about how great is the explanation... What about asking ourselves how could this all came together by chance?!
It's really fascinating and mind-blowing engineering. Think about it people
The creator. Who else !
small incremental change over billions of years. it didnt show up directly for human, even small rat like mammals had same structure millions of years back as seen through fossils.
No one claims it comes together by chance except those who do not understand science.
Exactly, it's fascinating how everything works so well together, there is so much that most people are ignorant of when it's already happening inside their bodies, it's just a miracle by itself that we as humans exist, God bless
Agreed. If they found a tin bucket on Mars, no one woud say: This bucket created itself over the last billions of Years. It just needed time. Now imagine a inner ear, creating itself over time. Insanity . Still: This video is very well explained.
I must say that this is the BEST educational video I've ever seen during my med school years! Thanks a ton!

i dont mean to be so off topic but does someone know a tool to get back into an Instagram account?
I somehow forgot my login password. I appreciate any tricks you can give me
yes i think so

I'm so thankful to the people who made it. The vestibular system is hard to understand only by the text, so this animation was very helpful to me. Keep going, fellows!
4 years at med school and this is the best educational video I have ever seen
Please add captions so everyone can access the info and understand the auditory system.
This is the best explanation of the auditory system I've ever seen. Isn't this yet another stunning example of the complexity and beauty of the human body?
Eric Olivier And dogs! And cats! And elephants, bats, whales, mice, etc....all the same, just as complex and dynamic. Quite neat!
And it all came together by "dumb luck," right?
@@imjustpassinthru7779 nahh iteration upon iteration of selective fitness! I like the idea of intelligent design but i realized that's b/c everyting else that didn't work up to survival par just didn't make the selective cut (and i believe the same could be said for astronomical bodies as well)
@@kyuhnfukaikage1283 Evolution's trial and error over an unfathomable amount of time sure can accomplish amazing things!
@@imjustpassinthru7779 allah god Almighty created us
I cannot believe that this video is 14 years old yet so good. This has helped me in med school and this person will probably never know it. But thank you anyways!
This is an incredible video, very helpful for anyone studying the anatomy and physiology of psychoacoustics. Would have been better if it had a more in depth explanation of the hair cells, but still a great video! Thank you!
Wow, full satisfaction, everything crystal clear !
This is the most well thought out and executed video on any anatomy subject I have ever seen. I just wish all anatomy subjects were created in this format.
Thanks to all the people who did the hard work of figuring this stuff out! Science is the way, the truth and the light.
+Chris Davaz just out of curiosity.. when you say Science is the way.. how do you account for the supreme intricacy of something as simple as the human ear.. that is.. are you of those who hold the opinion that such creation is merely chance and not a willful supernatural force i.e. God?
+Omar Ibrahim I think you are presenting a false dichotomy. The intricate "design" is the result of the laws of nature. I don't believe in the "supernatural", either something is real, and hence part of nature, or it is not. Whatever people don't understand they have historically attributed to "supernatural" forces (i.e., "God", "spirits", etc).
+Chris Davaz riposte! not sure what you mean by false dichotomy but I think I agree with everything you said, even though I believe in God.. I'm not actually sure what "supernatural" means either.. because to me god is still real and "natural" in some senses.. in any case, to me God is always the singular source of "the laws of nature" but I think there are certain cases where these "laws", as some people believe them, are equivalent to what I believe is God.. in other words, "the laws" as some people (maybe yourself) think of them are supernatural or eternal and our differences in belief become only semantic.. in another sense, we can say the laws of nature allow for many things, such as this paragraph I've written or the capacity for humans to build motor vehicles and global communications.. such things though, however intricate and complex they may be, are still ultimately insignificant when compared to the design and creation of something like the inner ear, or even the basic biology of a fly...
This is the BEST video on hearing, the graphics are awesome. I can understand the theory so much better.
Thank you all for so many positive comments on this video. I am glad we can provide it and pleased you are taking time to learn more about our amazing sense of audition. And I continue to forward on your many positive remarks to the creator of the film, Brandon Pletsch.
This animation of the ear is a work of art! Thank you. How wonderfully helpful.
Now if only you could make all of my textbook this interactive and awesome!!!
The best video I've ever seen , explaining gradually the function of ear! Congratulations to the designers!
Thank you for the kind remarks. I am glad you found the video helpful. And we can take no credit. The creator was Brandon Pletsch and he gave us permission to post it on our website.
THIS IS THE ABSOLUTE BEST VIDEO. like the small details on why round window and what goes on and how the membrane acts w low pitch high pitch is something which they do not explain in textbooks and are just written like the apical portion senses low pitch and base senses high pitch. but never explained. and ROTE LEARNING IS JUST THE WORST. once you see how and why and what. its engraved, no matter what, the conceptual clarity you get from just watching a 6 min video, it can never be removed. like how we forget whats taught in lectures and books. stuff like animations and pictures is something i personally cant. I LOVED THE WAY YOU SOLVED TEENSY DOUBTS LIKE WHY THE ROUND WINDOW and the cross section of cochlea. they just paste the picture of blah blah and write thats its ts or lateral without ever explaining it. and it angers me so so so much. tysm for the video
this is truly one of the best academic videos i've ever watched. i love the blend of art and science!
Can it get any more simpler than the way you presented it with this AMAZING video, accompanied with even more easy to understand pathway of sounds- one tiny section at a time? I am sure that even a kid would understand this university level material the way you presented it. A huge thanks to whoever involved with the production and publication of this video. Excellently done!
t a i’ll😂❤😂😂😂❤❤ 0:16 🎉
whats cool is that this is happening in your ear, but what is cooler is the fact that someone figured this out!
Incredible. Proof of design, especially the irreducibly complex ossicles and the oval window.
I can't believe someone actually made this. Thank you so much. For once I know which is which
My professor spent an hour and a half explaining what this video conveyed in 6 minutes, and you did it better than he did
Wonderful video. The music used to accompany this video about how we hear was written by Beethoven: a composer who had famously lost his own hearing.
This video is by far the best educational video I've ever seen. It really helped me understand the auditory pathway when studying for my MCAT. Absolutely incredible! Thank you
Excellent presentation! Thanks.
Amazing and stunning video with beautiful details!! Thanks for making it available.
C.R. Selvakumar Yes Indeed...
This is excellent. All healthcare professionals should watch this.
this helped me in A&P 4 years ago and now again for nursing school. thank you brandon for making this - many of us would be lost without you! (also, it's a beautiful video!)
Yes, as a physician, I concur with all the accolades about the quality of this excellent video. The song "Molto Vivace" that is the music, is Beethoven's Symphony No.9 in D-Minor, Op 125, the second movement (Molto Vivace). Enjoy! Oh, and Beethoven was deaf by the time he composed this work!
Thanks for the creators of this amazing 3D explanatory animation!
Absolute learning material! Thank you so much for your absolute presentation in 3-D animation.
THIS IS THE EASIEST WAY I HAVE EVER COME TO UNDERSTAND THE EAR ANATOMY. THANK YOU VERY MUCH FOR THIS VIDEO
Impressive! Thanks to Brandon Pletsch an Radius Digital Science.
this video was amazing! i've studied the ear so many times but never understood it to this extent until i watched this. thank you!
While the interjected loud music is super annoying, thanks for a yt that finally is able to show the 3d structures properly.
This is the state of the art explanation.
Thank you very much. I wish all knowledge could be transmiitted in such a way.
CONGRATULATIONS FOR THIS OUTSTANDING WORK!
Now this auditory system is what I call some really fine tuning of the human body. Great video.
Awesome and crystal clear, thanks for helping me reviewing ear physiology!
This is absolutely amazing, thank you so much for sharing this!
This was a super helpful video. It made it easier to visualize what was happening and the paths sound takes through the ear.
Amazing , it went straight to the point , used amazing animations , everything was perfect. Thank you!
This was absolutely the best. Helped me understand the inner ear so much more. Great video.
I watched this in 1st year for biophysics, and now I'm watching it for 5th year ENT :) The best presentation on this topic. Thank you!
I don't know what your actual intention of posting this video was but I can say that as a medical student this has helped clarify so much for me in the anatomy/physiology f the ear thank you so very much.
This is the best video so far that I have viewed. Thank you for the wonderful music and great views! I now have a better understanding for my midterm.
The stapes has a muscle attachment to limit the amount of travel to avoid over rebounding effect. A marvelous miniature device that is very effective within its appreciable considerably large ranges.
The BEST of all video education on how we hear. Thanks
made visualizing and understanding so much easier! thank you so much and please make more videos!! currently in medical school and could definitely use great instructional videos like this!
Unbelievably awesome!! Just what I needed to prepare for my A&P test! Thank you so much for sharing this!
thank you so much for this video! I'm studying for my phonetics exam (linguistics degree) and now this phenomenon has become so much clearer.
Fantastic video. It really helped me out with my upcoming A&P quiz. Thanks!
OMG...This video is made by a genius..Best educational video I've ever seen
Sooooooooooo beautifully illustrated and very creative. Thank you sooooo much!!!
truly Amazing thank you for this beautiful video ❤💚👍
like previous reviews said, this is excellent. Thank you!
I've been looking for animations for my physiology class and this was the most informative&helpful. Thank you so much. Also, the graphics were amazing!
HOLY MOLY I THINK I JUST HAD AN EARGASM. Excellent video! Thank you!
ㅈ한글로해석해주시면 좋게습니다
Beautiful. Thanks!
Thank you so much! This was exactly, I mean EXACTLY what I was looking for!
Exactly what I was looking for! seriously great job!
Excellent!!!! Beautifully done
I used to watch this several times as a kid‼️
super helpful!! my professor showed this in class and i searched all over youtube for it. so glad i found it!
Auditory Transduction Notes:
Outer Ear:
- Sound waves enter the ear and travel through the external auditory canal.
- Sound waves meet the tympanic membrane (eardrum) inside the ear.
- The tympanic membrane vibrates in response to sound, with pitch affecting the vibration rate and amplitude affecting the intensity of vibration.
Middle Ear:
- Three auditory ossicles (malleus, incus, and stapes) articulate with the tympanic membrane.
- These ossicles transmit frequency and amplitude information to the inner ear.
- The ossicles pivot together on an axis, held in place by ligaments (anterior malleoligament and posterior incudal ligament).
- Vibrations from the ossicles are transferred to the footplate of the stapes.
- The stapes moves like a piston, transmitting vibrations into the bony labyrinth.
Round Window and Cochlea:
- The bony labyrinth is filled with paralymph, and its flexibility allows vibrations to enter through the round window.
- The cochlea, a spiral portion of the bony labyrinth, contains the corridor leading to the round window.
- Vibrations return through the cochlea's spiral system to meet the round window.
- The ascending passage for vibrations is called the scalar vestibuli, and the descending passage is called the scalar tympani.
- Between them lies the cochlear duct, filled with endolymph and separated by Reissner's and Basler membranes.
Inner Ear (Cochlea):
- These membranes (Reissner's and Basler) are flexible and transmit vibrations back down to the scalar tympani.
- The organ of Corti is situated on the basilar membrane.
- The basilar membrane vibrates selectively, with lower frequencies vibrating closer to the apex and higher frequencies closer to the base of the cochlea, following tonotopic organization.
- The organ of Corti sends nerve impulses to the brain via the cochlear nerve.
- Specialized hair cells within the organ of Corti generate nerve impulses.
- Hair cells are covered by the tectoral membrane, and bending of hairs against it triggers the cells to fire.
Auditory Perception:
- The entire sequence of events, from sound waves entering the ear to the generation of nerve impulses in the organ of Corti, is responsible for our acoustic perception of the world.
Hope this helps!!!
You made me understand this in less than 10 minutes, my exams are tomorrow and luckily I understood everything because of you, thank you so much
This made so much more sense then how my teacher explained this in class! THANK YOU!
This is such an amazing video with incredible animations. Thank you very much
Amazing job on this video. Very helpful with understanding the process of the inner ear.
Thanks for posting! This has been a great help clarifying my notes for my A&P course.
This is a superb video! Thanks so much!
Excellent video!!
And great explanation :)
Thanks for sharing.
one of the best things i have ever seen.Thank you.
Thank you. I am studying medicine, and I have been struggling to understand the actually anatomy of the cochlea. Finally I understand. Finally!!!
Fantastic video. Can't wait to show it to my class. Thank you!
wow. the most beautiful video ive ever seen. imagining the liquid inside the scala, im speechless thank you so much for this video!
this is amazing. the most concise and easy to understand explanation of sound that I have ever seen. Thank you.
THIS WAS AMAZING clarified everything for me even though i'm studying veterinary medicine! Thank you so much, the visuals are fantastic.
Absolutely brilliant animation!
It is--literally-- an awesome video! Thank you...
This is so wonderful!! Thank you so much for sharing such a helpful and understandable video!
That was amazing! Thank you so much :) Please continue to produce more incredible work; you're so talented.
Very very VERY good explanation. I have read all sorts of explanations about this, and the details just never stuck with me, and turns out what I was missins was a 3D view of it all. Particularly the bit about the round window. Without actually seeing it there, I wasn't able to understand its function.
Great vid, really.
Wonderful job! God bless you
This is really the best video on this topic what I have seen so far on CZcams! Thanks : )
As the narrator indicates the tympanic muscle was removed to allow better visualization of the remaining structures in the middle ear. The tympanic muscle is thought to tighten the ossicular chain to limit the sound transmission to the inner ear. The purpose of this is protection. The muscle appears to act against impulsive sounds and also potentially to reduce the influence of our hearing of our own voice when we speak.
siick video! This is the finest graphical explanation of hearing.
This is an excellent video. Extremely well-done. Thank you very much for the effort you put into making it. Wow. If you know of others who have put similar effort into making videos explaining the function of other intricate human body systems (e.g. vision, olfaction, digestion/absorption, etc.) I would appreciate you sharing them with me. Really, this is terrific.
Excellent cut of the Cochlea with hairs that generate electricity for the mind.
That was great animation and explanation, thank you!!!
wonderful animation with great details thx for making it available
This is fab I have a exam on the ear tomorrow an this really helped me understand the inner ear and made it a lot clearer than simply reding about it!
This was very helpful! Best video! thank you!
Great video with a high level of detail.
Congrats on one of the best anatomy viceos ive ever seen
Im taking a music cognition course and this helped so much thank you!!!!
Couldn't really understand the anatomy of the ear, but this video helped me a lot. Thank you for sharing this awsome animation with us. Great job! :)
Thank you so much! Awesome video 👋🏻👌🏻
now this is amazing... thank you so much! you really helped me understand the ear, this is so much better than my life science notes!
