I thought this video was very fun and strange. I never new that younger ears were the best at hearing but I did know that older ears did not hear as well as younger ears. I could hear all the way up to the last frequency my mother could only hear to the third frequency. In conclusion this video was very helpful in learning abou the human body and how much it can take.
I honestly knew that younger ears were better for hearing. Watching this video made it clear and helpful to clarify that younger ear can hear better. Same as Emily I can hear to the last frequency and my mom can hear to the third. That's why when metal scratches metal it really hurts my ears. In conclusion this video was pretty useful.
I thought that this was a really cool video. I knew that younger ears worked better than most older ears, but I never knew why. I really enjoyed this video because it had lots of visual aids which always help me understand more. I think that this video could have gone into more depth. I could hear all of the beeps and my sister could hear all of them too. My parents could only hear up to the 4 th frequency. I loved hearing and watching the video because I felt like it taught me a lot and was very fun and interesting to watch. I would rate this article/ video about a 9/10 star rating because I felt like it could have been a little bit longer and more descriptive.
I enjoyed this video, but it kind of stated the obvious. Everyone knows that younger ears can hear better than older ears. However, it was interesting to find out that there are such things as hair cells that pick up different frequencies to send to your brain. I also didn't know that when you get older, your exposure to sound can brake those cells. My dad was able to hear until 16,000 HZ and my mom was strangely able to hear everything except for 15,000 HZ. I thought it was very cool that you got to test out how old your ear was. Still, I wish that the video was longer and had a bit more information. Overall I give this video a 4 out of 5 stars.
I thought that this article was very interesting. I had already known that the older you get the harder it is to hear high pitches. I never new that it was because your hair cells inside your ear were braking down. The only thing that I wish the video would have done is explain it more. I still have a lot of questions from that video. Overall this was a 7 out of 10 star video only because it didn't go into more depth about the subject.
I really loved this video. Since I am always watching ASAPScience this was really fun for me. I loved testing all the frequencies. I knew that once you get older it gets harder to hear those sounds, so that wasn't a big surprise for me. I really liked this so I would probably rate it a 8/10 because I really enjoyed everything about the video. Thanks to Abby for providing this awesome video!
I knew that younger ears were better at hearing than older ears. This video was very interesting, and it helped me discover the limits of people's ears. Same as Bianca and Alec, I think the video could have been in more in depth about why younger people hear better than older people instead of just having the hearing test. I would like to know a bit more about the science of why this occurs. Overall I rate this 7.5 out of 10.
This is a cool video. For the hearing test, sadly, I stopped hearing after 15,000 hertz. However, on the next one, it was almost as if I could hear the very beginning of the sound and not the rest, as if I could "feel" the sound but not hear it. Also, did anyone else hear the clicking sound that constantly appeared throughout the video? I have taken hearing tests similar to this one before, but this one was better because none of the other ones actually told me why I couldn't hear some of the sounds. It's good to finally hear about how this works. In addition, I think that maybe the environment you live in and things you do affect your hearing. For example, I stopped hearing after "under age 40." This might have to do with the fact that I have two screaming little brothers and have been playing loud piano for 3 1/2 years. The extra noise may have damaged my hair cells early. Lastly, I remembered that dogs hear at higher pitches, so I played the video for my dog to hear. Sadly, he didn't react much, but it's always good to see what happens! Overall I give the video 8.5 out of 10 stars.
Lilah, I had the same problem as you. If you can't hear the sound, it means that your headphones can't support those frequencies. If you heard the clicking sound, however, you still can hear the frequencies, even if you don't have the right headphones. So if you heard a clicking sound for the whole thing, you're good to go. I like this video a lot, but just like Lilah, I could not hear 16000 hertz or higher, but I could still here a clicking sound. If you have good quality headphones, I recommend using them because the school headphones do not support frequences of 16000 hertz or higher. Other than the problems with headphones, this video was really cool, even if it did state the obvious. It was interesting to learn how as your ear gets older you cannot hear higher pitches.
This was a really cool video, although I did have some problems with the test portion of it. Like Lilah, I only heard the clicking for the last few frequencies. I would have loved to have gotten more accurate results by using better quality headphones, which I don't own. The reason I know that my results weren't accurate is because I also had both my parents listen to it and both their results were the same as mine. But I also wonder if the video was wrong in the ages it was giving. Because my parents could both hear up until under 40 and might have been able to hear for longer if the sound quality was better. I rate this video a 7/10 because I think it could have been more accurate in the ages it gave.
Although I though this video was fun, especially because of the stop motion animation, I did not think it taught me anything. Firstly, it was only a minute and a half, and that is never enough time to describe anything. You could get more deep information by just looking it up. Also, I definitely agree with Bianca, this is just stating the obvious. Yes, it was nice to find out why though. I did wonder, why are they called hair cells? It turns out, under a microscope, it actually looks as though there are mini hairs on the cell. Lastly, it seems as though this experiment could have been better conducted. I wasn't wearing headphones, and I couldn't hear anything under 40. That poses kind of a problem. I would also love to see the placebo effect being used during an experiment like this, where people said they heard something, but nothing is playing.
I think this video is extraordinarily interesting. Although I knew that old age impairs a person’s ability to hear high frequencies, I was not previously aware of why. After watching this video, I formulated a few questions. First, I want to research more about the mechanics of the human ear, and how we understand and process sound. Additionally, I would like to research what frequency ranges humans can typically hear between. Lastly, I know that some animals can hear much higher and lower frequencies than people. I would like to what know animals they are. Overall, though this video is pretty short, and doesn’t go into too much depth, I still think it is very interesting and engaging. I thoroughly enjoyed watching it.
After further research in the hearing process, I have found the answers to the questions I posed earlier. First, I have now really grasped how amazing the human ear is. The hearing process is truly extraordinary and exceptional. Our ears can be categorized into three sections, the outer ear, the middle ear, and the inner ear. The ear canal and the eardrum make up the outer ear. Sound goes through the ear canal and hits the eardrum, which makes the eardrum vibrate. Three small bones, known as ossicles, are located in the middle ear. The middle ear is basically a space that is located behind the eardrum. These bones are “connected to the eardrum” as well as to an “opening in the inner ear.” When the eardrum is vibrating, it forces the ossicles to vibrate as well, which then makes fluid move in the inner ear. Because there is movement of fluid in the ear, small structures named hair cells are moved and changed slightly. The movement triggers electric signals that go from the inner ear through the auditory nerve and to the brain. The brain is then able to “interpret the electric signals as sound.” As for the range of frequencies humans can hear, there appears to be a discrepancy with different sources reporting different ranges. However, most sources I reviewed agreed that a human can hear about 20 Hz to 20,000 Hz. On the other hand, one source claimed humans can hear 64 Hz to 23,000 Hz, but I have not found additional sources in agreement with this claim. It is my belief that the range of 20 Hz to 20,000 Hz is the most accurate for the range of frequencies a human can hear, as, like I stated above, the majority of the websites I visited contend that this is the range. Additionally, one source stated that humans ordinarily have conversations that range between 1,000 Hz to 5,000 Hz. As a result, the website believes that humans can, for the most part, easily hear frequencies between those two numbers. Similar to the information about the range of human hearing, a number of inconsistent claims exist about the rang of frequencies animals can hear. However, multiple sources agree that dogs, horses, bats, and dolphins have a good range of frequencies that they can hear. Dogs can hear around 40 Hz to 60,000 Hz, but the range can change if the age and breed of the dog is known. Along with that, bats have exceptional hearing, but websites have contradicting information about just how high of a frequency they can hear. One website claims that bats can hear up to 150,000 Hz, while another says 100,000 Hz, and another says 110,000 Hz, and another claims 120,00 Hz is the highest frequency they can hear. The truth is, it is high, and it is around those number, but the real and exact number is not easy to ascertain, and may depend on the species of bat. Additionally, one website believes the lowest frequency bats can hear is 1,000 Hz, while another thinks it is 2,000 Hz. Dolphins are another very controversial animal in terms of the range of frequencies it can hear. Three sources believe that 1,000 Hz is the lowest frequency dolphins can hear, but other sources have different ideas. One source contends that the lowest frequency dolphins can hear is actually 8,000 Hz, but since multiple sources believe it is 1,000 Hz, that number seems most probable. Additionally, some sources think dolphins can hear up to 150,000 Hz, while another thinks 164,000 Hz, while a different source believes 200,000 Hz. As for horses, yet again different sources make different claims. One source claims horses can hear 14 Hz, to 25,000 Hz. An alternative source believes horses can only hear 31 Hz to 40,000 Hz. Overall, I really enjoyed learning about the human ear, and the range of frequencies humans and animals can hear. The video is very interesting, and I also loved reading about information from my own research as well.
I found this article to be fascinating. I already knew that the younger ear was better than the older one because old people can't hear as well as they used to, but I could hear all the beeps even though I wasn't supposed to. Would babies be able to hear everything including really high pitched sequences
This video was really interesting. I didn't know you could determine the age of a person's ears by turning the pitch higher and higher. I could only hear the first three pitches, but I could hear any more. It is really fascinating that some people can hear the sound and some people can't. When I watched this video, I brought the connection to dog whistles because when a person blows a dog whistle they can't hear it, but a dog can. It is because dogs have good ears and the frequency is higher so humans can't hear it. It is also amazing hair helps us hear sound. So, when the hair gets run down we have older ears. I would give this article a 7/10 because it taught me a few new facts, but I wish it gave me more information.
