PRESENTATION OUTLINE

FIRST WE THOUGHT OUT THE QUESTION.

Make a box that will reduce the sound for your IPhone.
We started off with buying a pair of shoes,-
-and using the box it came with.
Limitations: least amount of mass, must fit on a-
-pice of paper, and must have good sound reduction.

THE GATHERING OF THE INFORMATION

We looked up sound proof items.
We found carpets are decent at sound blocking.
We added a second layer into the box for less sound.
The information is from www.wikipedia.com

ALTERNATE IDEAS

Idea 1: Put sand into the box
Idea 2: Put water into the box
Idea 3: Put sand with water into the box and duct tape it
Idea 4: Use carpets and other light, sound resistant items

PROS

Idea 1: The sand would be great with sound reduction.
Idea 2: it would also reduce sound.
Idea 3: the mixture would make it to a mud-
-like substance, blocking the sound.
Idea 4: it fairly increases the mass.

CONS

Idea 1: the sand would increase the mass
Idea 2: the water would seep through the box
Item 3: the sand/water would be too much mass
Idea 4: the mass is reasonable and the sound-
-would be fairly quiet

THE SOLUTION

We went with the carpets
It is light and doesn't have much mass
It is good at being sound resistant

THIS IS THE PROTOTYPE

Our results were: out: 22.9
In: 34.6
Diffrance: -11.7
Mass: 1470 grams
Efficiency: -0.007959183673469
