The act of hearing is something the whole body has to work on; even the skin. When people saw a video where somebody was saying "ga" but the audio was playing "ba," people thought they heard a completely different sound—"da." Then when they mixed audio with a sense of airflow, researchers have found that our perception of certain sounds relies slightly on being able to feel these sounds. When people say the letter “p”, “t”, and “k” a puff of air is produced that most people do not even notice. This feeling of puff helps the person distinguish “p”, “t”, and “k” from other letters. Why skin contributes to hearing could be because the largest organ in the body is covered with mechanoreceptors. These receptors in skin cells that are similar to the ones in ears respond to the pressure created by airflow.
This article doesn’t necessarily affect humanity. But, it effects life in general. I think this because before, nobody knew that skin had a lot to do with hearing. Little did people know, the puff sound that comes out of our mouth helps our ears distinguish letters.
I thought this article was very interesting. But, one thing I would change about this article was that some parts became very confusing. When it came to the part about “p”, “t”, and “k” I sort of lost track on what they were trying to say. Therefore, I hope I explained it a little better. I also thought they could have shortened this up because there was a lot of useless information.

Nell's article summary was very well written and I specifically liked how she chose an article that was a little tough to understand and managed to process that article and turn it into an understandable form. I also liked how she talked about the skin receptors in the skin cells that act like ears. This was a new fact that i really enjoyed learning. I also liked how Nell distinguished which specific letters produce the "puff" of air that is normally not noticed. Next time i say a word with the letters "p", "t", or "k" in it i will be sure to try and see if i create the puff. I think that the only down side to this article was that Nell stated that this article doesn't effect humanity. Well, it certainly does because it brings to people's attention more knowledge about the human body. From this article I learned a great deal and Nell did an amazing job at writing her article. Lastly all that Nell would have to do to improve her article is to double check her spelling. For example she said "affect" where she should have said "effect". Just a few minor spellings mistakes but overall a job well done!!

I thought Nells article was really well organized. she got to the point and made it very easy to understand this article. To make this review better Nell just could have spell checked. I also don't agree with her when she said this doesn't effect humanity. I think that it effects humanity in a way that people can be more informed about the way that the human body works. There are just a few spelling and grammar mistakes but overall she did a nice job. I was impressed by Nells choice of article topic. I thought it was an interesting topic to cover and one that i would never have expected.
ReplyDeleteThis review was well written and covers an inquisitive topic. Three things i Liked were that nell made everything understandable with " marks so we understood what she is trying to pronounce. Another thing that was great was how interesting she made the review for the reader. She really pulled the key points out of the article. Thirdly, this is a very relavent topic as we are always trying to learn about skin AND human nature, and this is a topic where they collide. One thing that needs improving is Nell saying how it doesn't effect humanity, but in my opinion thats false since everything we learn about ourselves affects us. I learned alot about speech and an odd use of our skin! Declan Considine
ReplyDeleteNell, I thought you did a very good job with your review. Your article choice was very interesting and I enjoyed reading your review. You did a great job at making it just the right length, not too short and not too long. You also made it pretty clear to understand, which was a relief. There were a couple of things you could have done better though. One you could have made your summary of the article a bit shorter because truthfully we just want the gist and not much more. Another thing that you could have done to improve your article is that you could have checked your grammar a bit better because I think in like your second sentence you said “saw” when I think it should have been see. I learned a lot from your article and one of the things I learned was that we can hear with our skin, and that there are special puffs of air for certain letters and words that we can feel. In summary you did a fabulous job with your review well done.
ReplyDeleteNell did a great job doing this review. I liked how she chose an interesting topic so it brought me in. I also liked how she used the "puff" noise so that we understood what she was talking about. She could have wrote less about the unnecessary elements we as readers do not care about. I thought this was very interesting and entertaining to learn about because would have never thought about it before this article. GOOD JOB NELL
ReplyDeleteThis was a great article review! Nell did a great job making the article, short, concise and to the point. Both the review and the article were not to scientific, so they were both easy to read and comprehend. Though the review was for the most part great there are a few things that needed to be worked on. I thought that Nell got into the phonetics meaning the "k" "t" sounds which i don't think needed to be included in the reivew. Also i have noticed a lot of spelling and grammar mistakes.I found this article very amusing and something that i wouldn't typically think about. Nice Job NEll!
ReplyDeleteI read Nell’s article called, “People Hear with Their Skin, As Well as Their Ears.” Nell’s article was very well written and I enjoyed learning about this, because I didn’t think it was possible to hear with skin. I enjoyed how Nell put the words she was trying to pronounce in quotations so we could understand what specific word or letter she was talking about. Nell’s article was a good length, not too short but not too long.
ReplyDeleteOne thing she could have done better though was to shorten it just a bit by getting rid of the unnecessary components of the article that wasn’t very important. Cutting it down will make it easier to understand. Another thing she could have done better was to check spelling and grammar because I noticed mistakes throughout the summary.
I found this article very entertaining, and I will surely notice next time I make a noise that could allow my skin to hear!
This was a good article review by Nell. She explained clearly made the point about how your skin really does help you hear as well as your ears. Her examples were good, about the people listening to the video and the "puff" noises. Also, I will now take more notice if I make the "puff" sound the next time I say a word with the letters "p, t, or k" in them. Although this was a great review, the grammar could have been improved. Secondly, I am slightly confused about how the "puff" sound makes you hear better. Other than that, this was an interesting article review about a topic I never would have thought about!
