Randomized trial analyzes sound absorption in porous materials, suggesting edge conditions improve performance.

This research aims to explore how different edge conditions impact acoustic wave propagation in porous media.
Employed mode-matching technique for analyzing acoustic wave propagation.
Investigated three edge conditions: zero-displacement, zero-gradient, and spring-like.
Evaluated three porous materials: A-glass, E-glass, and basalt wool for their acoustic performance.
A-glass showed the best sound absorption performance across all edge conditions.
A-glass achieved greater transmission loss over the entire frequency range with significant improvements.
Spring-like edge connections enhanced acoustic performance by increasing sound attenuation.
