Numerical Methodology to Obtain the Sound Absorption of Materials by Inserting the Acoustic Impedance

Numerical Methodology to Obtain the Sound Absorption of Materials by Inserting the Acoustic Impedance

Numerical models allow structural characteristics to be obtained by solving mathematical formulations. The sound absorption capacity of a material can be acquired by numerically simulating an impedance tube and using the method governed by ISO 10534-2. This study presents a procedure of obtaining so...
