Introduction
After having chosen to study foams, and focused on their acoustic properties, we looked for experiments in order to characterize them.
As the ENSIACET is not equipped to do acoustic measurments, we first contacted the acoustic laboratory called P.H.A.S.E (Physique de l’Homme Appliquée à Son Environnement) to help us, but they never answered.
Then, we asked the IUT of applied physics and insturmentation of Paul Sabatier University in Toulouse which gave us a positive answer. Thanks to the teacher responsible for the acoustic lecture, we got the chance to realise tow acoustic experiments on our foams. Hence, we were able to determine and compare their absorption coefficients.
