Soundproofing device for a high school demonstrative project

[phyte_0450]

Hello to all. I am a 4th year High School student.

For my demonstrative project I was planning to make some kind of soudproofing device. Does anybody know how to make an effective one and what materials to use?

Or does anybody have any other suggestions for a demonstrative project? I have around 2 weeks to do it. Thanks for any help.
