Different materials can be used to absorb sound. The best absorbers are materials like wool or styrofoam; stone slabs do not absorb sound very well. When a house or apartment is being built, carpets are laid on the floor, ceilings have a layer of styrofoam, or sound-absorbent tiles made of compressed cardboard are used.

Information and ideas:
With the help of the experimentation instructions, the students should find out for themselves in an experiment which materials are most suitable for sound absorption. They can work through a list of materials and should come up with their own ideas of insulating materials.
