What is Insertion Loss in Sonic Crystals about?

This paper investigates the insertion loss of sonic crystals made with multi resonant shells, specifically focusing on combinations of coaxial resonant shells with slits and perforations. The study reveals that these configurations can create additional bandgaps and enhance low-frequency noise attenuation through dipolar resonance effects. Simulations and experimental validations demonstrate the effectiveness of these multi resonant scatterers in improving sound attenuation properties.
