How did we choose them ?

In order to see through our project about cellular materials, we first chose to adopt an approach focused on their acoustic properties.

For this, we bought sound insulating materials used in construction industry (polyurethane foams) and for human ear (earplug) in order to characterise them and to understand how they work.

Then, we decided to make the connection with natural cellular materials used in the same cases. Therefore, we studied cork.
