ConclusionIn conclusion, this experiment showed the most effective of five selected materials at blocking out sound. The hypothesis predicted that the denser a material is, the more intensity is lost as sound passes through that material. Thus, the most intensity lost is with the metal, and the least with the wool. The results validated my hypothesis because metal lost the most intensity of a constant sound source and wool lost the least. Conclusively, the denser a material is, the greater sound intensity is lost as it passes through it. Metal is the most effective material at blocking sound followed by clay, wood, foam and wool. It is recommended that this experiment be replicated for further investigation.

The more packed the molecules are, the more intensity lost.
