Acoustic Absorption of a New Class of Alumina Foams with Various High-Porosity Levels

Recently, a new class of ceramic foams with porosity levels up to 90% has been developed as a result of the association of the gelcasting process and aeration of the ceramic suspension. This paper presents and discusses original results advertising sound absorbing capabilities of such foams. The a...
