Design and modeling of a periodic single-phase sandwich panel for acoustic insulation applications

Sandwich and composite panels are widely used in acoustic applications due to their sound insulation abilities that surpass mass-law partitions in medium-to-high frequency zones. The design of acoustic panels is based on the control of the resonance-dominated region of the sound transmission loss curve, which is a key component. With respect to conventional single-layer designs, such devices usually exhibit acoustic inability and poor insulation performance within a given frequency range. We want to introduce an innovative twist to the sandwich partition model in the present essay. By adopting a regular repeat of a properly planned unit cell, a novel single-phase sandwich panel is realized. A series of parametric tests has been published to demonstrate how the topology of the unit cell influences the panel's noise reduction capability. Industrial and production considerations are also taken into account during the manufacturing process to ensure the solution is commercially valid with a circular economy emphasis.
