| A slide from the PowerPoint presentation- |
Mr. Barbone, John's dad and professor of mechanical engineering at Boston University, spoke to us about acoustics, the science of sound.

Thank you so much, Mr. Barbone, for taking the time to share with us your favorite hobby, Acoustics, The Science of Sound. The sound made from the Tibetan singing bowl, an ultrasonic fogger, was really cool!

Dear Benji,
DeleteMost sound is created by something vibrating, yes. Even our speech. Speech is created by the vibration of your vocal cords. They're kind of like biological guitar strings sitting in your throat.
-Paul Barbone
Thank you a lot for the presentation.I thought acoustics were really cool.It was very interesting when you showed us how the music box vibrated to make music. Do most things make sounds by vibrating?

Thanks you, Mr.Barbone for coming to our classroom and teaching us about your career. I loved hearing to the singing bowl and the little music players that were handed out. I also thought that the slinky example was fun to watch. Thank you again for coming to our classroom and sharing your very cool job

Dear Mr. Barbone,
ReplyDeleteThank you so much for coming in and teaching us the different ways sound can be used! I think Acoustics are really interesting. I also thought it was really intriguing that sound can be seen, for example in the earthquake. I also thought the Tibetan bowl was really cool@

Can sound make killer radiation?
ReplyDelete__ Adir
Dear Adir,
DeleteYes, sound can be made powerful enough to destroy things. We use sound this way medically. Kidney stones, for instance, are little stones that sometimes form in people's kidneys. They can cause great pain, and can be very dangerous. The "old fashioned" way to cure a patient of kidney stones is to surgically remove the stone. (The patient is cut open, and the stone is removed.) Instead of cutting people open, however, we sometimes use a procedure called lithotripsy.
Lithotripsy (litho = stone; tripsy = pulverize) is a procedure in which a high powered sound wave is focused on the stone. The sound wave breaks up the stone into little pieces, right inside the body, without hurting the tissue in between the stone and the skin.

Thanks so much for coming to team 64! I thought your presentation was great. I especially loved the "dancing" water!

Mr.Barbone,
ReplyDeleteThank you VERY much for coming in to show team 6 4 your STEM related job! In your presentation the music box caught my eye because i never knew that the vibrations made the music?! I have one of thoes and never really knew how it worked but now I do. Another thing that I thought was interesting was the Tibetan Singing bowl because the way that you just rubbed the bars on the bowl made the water vibrate! What
is the purpose of the Tibetan Bowl? Where did you get the bowl? Thanks, Isabela P.
Dear Isabela,
DeleteThe Tibetan bowl was my favorite part of the presentation, too. I got it from a friend of mine. It's a kind of "singing bowl" which is used in some Buddhist practices. They are generally used to call people to prayer, or sometimes as part of the meditation ritual. You can read more here:

Thank you so much for coming into our class!I really liked how you used a slinky to demonstrate sound frequency, and how you made the presentation more interactive by passing around music boxes. Thanks again!

Thank you for coming to our classroom. Everything that you showed us was really interesting. I thought that the Tibetan sing bowl was fascinating.

Thank you so much for coming! I thought it was interesting when you told us how an organ pipe worked, I have always wondered. I thought the singing bowl was cool too. Thanks again!

Thanks so much for coming! I thought that the things you taught us were really facinating! Thanks again!

Wow this was an interesting lesson about acoustics. But I wonder if sound involves energy and how much energy. Curran.c
ReplyDeleteDear Curran,
DeleteI'm glad you liked the presentation. I had fun putting it together.
Yes, sound involves energy. Very loud sounds actually require very little energy to create. A 707 at full throttle (one of the noisiest passenger jets ever!) emits only enough sound energy to cook an egg.
Nevertheless, sound can be used to transmit energy from one place to another. There is a recent invention that uses ultrasound to remotely charge wireless devices. The idea is that the sound waves can harmlessly fill a room. Since they are ultrasound waves, people can't hear them. We can make our devices (e.g. cell phones) hear them though, and design them to suck the energy out of the sound waves to recharge their batteries. No cables! Isn't that cool?

Thanks for coming to our class!! The lesson was very interesting. I never knew that you can use sound to make heat and heat to make sound. I also liked the Tibetan singing bowl.
ReplyDeleteThank you again,
Maya
Thanks so much for coming, I had a blast. I really enjoyed it. It was very fun
ReplyDeleteThanks,

Thank you so much for coming in and teaching us something new I thought the dancing bowl was really cool and interesting. I wish we had more time.

Thanks Mr.Barbone for coming to our class and teaching us about acoustics. Your demonstration with the singing bowl was so interesting!! Also your explanation about the organ pipe was fascinating!! Thanks again!
ReplyDeleteNoy
Thanks for the great presentation. I liked every part about it. If I had to choose my favorite part I'd say the Tibetan Singing Bowl.
ReplyDelete-David
Thank you so much for coming to our classroom to talk about Acoustics! I enjoyed your presentation and I liked the singing bowl. I also thought that the thing with the water was pretty cool.
ReplyDeleteThanks!

Thank you for coming, I enjoyed it a lot. I really liked the tibetan singing bowl, the sound it made was very cool.

Thank you Mr. Barbone for coming to our class and talking to us about acoustics! I enjoyed every part of the presentation, especially the musci box and the singing bowl.

Dear Mr.Barbone,
ReplyDeleteThanks so much for coming in to teach us about your job. I thought the dancing water bowl was really cool! I also thought that how you could see with sound, and that sound could make light was awesome!
Thanks,
Emma
thanks for coming to our class but i have a question how does a machine make a certain sound
ReplyDeleteEthan S
Thank you for coming into our school to teach us as team6-4 about acoustics . I love playing with the music box.

Dear Ms. Sullivan and Team 64:
ReplyDeleteThank you for hosting me in your class on Monday. I had a great time and wish we had more time to talk about acoustics, and mechanical engineering more generally.
Sincerely,
-Paul Barbone
Thank you so much for visiting our classroom to talk about Mechanical Engineering Mr. Barbone! I really liked your demonstration with the singing bowl and the music box. I learned that you can not only hear sound, but see sound. your presentation was very interesting and I learned many new things. Thanks again!!!!!!
ReplyDeleteSincerely,
Yordi
dear mr. barbone,
ReplyDeleteI loved your presentation! My favorite part of your presentation is the music box that you passed around! I couldnt believe that when it was in the air it made a lower sound then when it vibrated on the desk. another thing i was interested in was the tibetan singing bowl! I loved how loud its noise was and i was amazed at how it made the sound by rubbing your hand on its sides! I found out that it also works on a glass rim!
thank you again for taking the time out of your day to come and teach us new amazing things!
sincerely,
Jennifer Lipof
Thank you Mr. Barbone! That PowerPoint you showed us was very interesting! I loved the picture of the dancer in motion! That's so cool and I want to draw something like that! The Tibetan singing bowl was really coo too! Thanks again!

thank you for teaching me about sound i really wanted to know how sound went threw walls thank you so much

Thank yout for coming in to teach us about sounds. It was very intresting, I can't believe that ultrasound can be used to power electricity. Thanks again.
ReplyDeleteKaren
Thank You for coming into our class, i really enjoyed watching the singing bowl and ultrasonic fogger. It was also cool to see the oscilloscope
