Science – Sound Insulator Investigation

 

In Science today, we were investigating which materials make the best sound insulators.

 

Miss Felton had a problem. She couldn’t sleep because her neighbour’s snoring was keeping her awake. So 4F wanted to help her to get a good night’s sleep by making her some sound blocking ear muffs.

We discussed how we would make the test fair to get the most accurate results and we decided that we would keep the volume of the sound the same for every test, we would make sure that the material covered the ear and also that the thickness of the material was kept the same.

Next we made predictions about which material we thought would make the best sound insulator. What was your prediction and can you explain why?

Do you think bubble wrap is a good sound insulator? Why?

Do you think that tin foil is a good sound insulator? Why?

Do you think cotton wool is a good sound insulator? Why?

Do you think sponge is a good sound insulator? Why?

Do you think paper is a good sound insulator? Why?

 

Fingers crossed that we can find the best sound insulator so that Miss Felton can sleep peacefully!

    I predict that bubble wrap will make the best sound insulator. I think this because I think that the air will stop some of the vibrations entering the ear.

  2. Grace says:

    I predict that paper will insulate best because if it’s in layers it’s harder and stronger than any of the other materials

  3. Dubai says:

    I think umm the sponges are the best because the sponges have only tiny holes not big holes so I think is the best :)

    • zarah says:

      I think the spong because if you fold it. It looks like it can keep away sound.
      I think the paper will be the worst because it seems to be fike so the sound will come into my ear.

  4. Rovaughn says:

    I prudict that plain paper is the best sound isolator beacuse when u put paper on yours ear the air dos’nt escape from ur ears.

    .

  5. Paul says:

    I think that the sponge would work best because it has holes with dead ends so it bounces off.

  6. Honey says:

    I think it is sponges because the bottom part is rough either way it is it will always reach the rough part Is thick so it will block the vibrations coming through your ear

  7. Hannah says:

    I think that the best sound insulated because it is the most thick therefore insulating more sound.

  8. Jayden says:

    I predict that the sponge is the strongest insulator . Because it looks the thikessest thing there(hopefully I’m right)

  9. Emmanuel says:

    I think that the sponge will because it’s really big and soft and no vibrations will be able to get through the ear

  10. Naomi moses says:

    I think the best insulator material is the washing sponge because the sponge has more layers so most of the vibrations don’t interfere with you ears

  11. Enyi says:

    I think that the sponge will be the strongest insulator because at the bottom there is this strong green stuff that you can not tear so I think that will block out the sound

  12. Jamai says:

    I predict that the cotton balls are the best sound insulator because they have a thick layers and it is very strong to.

  13. Priscilla says:

    I predict that the sponge will ok because it has a big block of protection on the sides. It also has a thick layer to keep the sound of the vibrations out.

  14. Adeeb says:

    I think that the tin foil is the best sound insulator because if you turn it into a ball you can fit it in your ear and the tin foil has no holes so when the vibaration try to get in there will be no space

  15. Lucie Carnoy says:

    I predict that the cotton wool balls will work out the best way because they have no holes.

  16. Anastasia AM says:

    I predict that the best insulater because it is the most thick therefore insulating more sound & I think the best meterial is sponge.

  17. Priscilla says:

    Sorry I meant the sponge will work.

  18. Cheick says:

    I predict that the sponge will be the strongest beacuase it big

  19. Bryan says:

    I predcict cotten wool would be the not the sterongest sound insulator becaues holes are in side so the vibrations will get through to the ear.

  20. Tamanah says:

    I predict that paper will make the best sound insulator.l think this because the vibrations would not go in your ear.

  21. Dubai says:

    I fink they will all work asept for the paper one 😀 and I think the 1 that will work the best will be the sponges

  22. Rovaughn says:

    The worst insulat is the bubble wrap because when u lay on the right or left u can pop all of them in one second and u would hear the snoring again.

    The sponge is okay beacuse it’s soft but it’s not that strong because it’s a sponge and u wash the plates with them.

  23. Hannah says:

    I think the worst sound insulater is the paper because it is so thin.

  24. Adeeb says:

    I think that the worst sound insulator will be the sponges cause it has holes that will let the vibaration go through:)

  25. Honey Williams jones says:

    I don’t think that the bubble wrap would work because it makes a loud sound it self

  26. Jayden says:

    I predict that bubble rap is the wores insulator. Because it looks thin✌✌✌

  27. Anastasia AM says:

    I think the worst insulater is going to be paper because it’s far too thin

  28. Tianna Collins ❤️ says:

    I think that the cotton wool will be the best thing out of all of them

  29. Priscilla says:

    I don’t think the bubble wrap will work because if you turn around and lay on it the bubble wrap I’ll start to pop and make a lot of noise.

  30. Jamai says:

    The worst sound insulator to me is the bubble wrap because it is so thin

  31. Enyi and Grace says:

    Grace thinks that the sponge will be the worst because it is soooooooooooooooooooooooooooooooo soft and spongy (it’s in the name) it will work against it. Enyi thinks that the bubble wrap won’t work becuase it is so thin

  32. Andy says:

    I predict that the paper or cotton wool the paper because it is stronger and if we fold it it will be thicker and stronger⚽️ I don’t know I think hopefully I’m right hhhhhhhhmmmmmm

    So what was the best?
