What is it about?
Here is presents an acoustic material for broadband and low-frequency sound absorption based on Cantor fractal geometry. An theoretical fractal porosity was established to better described the behavior of the absorber proposed. The results of experimental tests confirmed that the fractal absorber has broadband sound absorption and presented good agreement with the theoretical and numerical models.

Why is it important?
Because this work contributes to the understanding of the use of Cantor fractal porosity in the proposal of new absorber that allow low-frequency broadband absorption.
