I need an effective and interesting experiment on sound insulation?

Im in year 12 and have an assignment, in this assignment I need to undergo and investigation into a physics concept.

Therefore I am going to study sound insulation and to do this I have access to a sound sensor that records sound and then represents the data onto a computer.

I am thinking of doing an experiment along the lines of surrounding a speaker in 5 different materials and measure the level of sound produced outside the materials to find which material best insultes sound waves.

Can you please help/contribute ideas to make this experimental investigation effective, smart and interesting for its audience (my teacher).

Any sort of help is awsome
