Introduction
The project we have chosen to investigate is ‘What materials
block out sound effectively?’ We will try to find out which
material is the best sound insulator.
We got this idea with the help of our teacher, Mr.Tynan and we
have decided to do this project because we thought it would be
interesting and fun to do.
To investigate this, we will use a variety of materials such as
cotton and denim. We are also going to use a microphone (to
gather the sound), a Lab Quest (to measure the sound
differences on graphs) and also a 2 litre bottle to block the
sound occurring throughout the room.
We are hoping to find the best insulator, which we are
expecting to be egg carton, and good graphs to show the
results clearly.
Summary/Abstract
The name of our project is ‘What materials block sound
effectively.’ We were trying to investigate which material is the
best sound insulator.
The materials we decided to use were cotton, polycotton, egg
carton, denim and paper.
To investigate this we decided to connect a microphone to a
Lab Quest and place the microphone in the mouth of the
bottle. We then placed each material, one at a time, into the
bottle. Finally, we repeated the same phone alarm for each
material and recorded each sound difference on a graph.
After carrying out this experiment, we have learned that denim
is the best sound insulator out of the five materials we
investigated on.
Experimental Procedure
We connected a microphone to a Lab Quest.
Then we placed each material (one at a time) in
the bottle and placed the microphone in the
mouth of the bottle.
We used a phone to repeat the same sound
through each material as the Lab Quest was
recording the sound difference on a graph.
Results
No Insulator CONTROL = 3.060

Are investigation showed
that out of the five
materials we have tested.
Denim is the Best sound
insulator.
Conclusion
After carrying out this project, we have
discovered that Denim is the best sound
insulator and the egg carton was the
worst.
