A soundproofing experiment

We wanted to see which materials were best at muffling sound. First we had to make sure our test was fair by making sure everything stayed the same apart from the materials being tested. We realised we had to keep the same sound source and remain the same distance from it. We used the same number of layers every time we wrapped the sound source.

 

 

We found that the cardboard and the fabric muffled the sound best.
