This paper deals with an investigation on a multilayer panel suitable for noise insulation and absorption joined with electromagnetic and thermal insulation properties. Two nickel-based materials were studied: sinterized nickel (SN) and green nickel-copper (GNC); they are characterized by high acoustic insulation and electromagnetic shield properties. SN and GNC layers were coupled to low density polyethylene foam layers (LDP) in order to improve thermal and acoustic abatement performances. Acoustic absorption and transmission loss were measured for different configurations based on the investigated materials. Measurements were carried out by impedance tube method. Results show that the best performing panel is the one constituted by SN and LDP layers.

Abstract

This paper deals with an investigation on a multilayer panel suitable for noise insulation and absorption joined with electromagnetic and thermal insulation properties. Two nickel-based materials were studied: sinterized nickel (SN) and green nickel-copper (GNC); they are characterized by high acoustic insulation and electromagnetic shield properties. SN and GNC layers were coupled to low density polyethylene foam layers (LDP) in order to improve thermal and acoustic abatement performances. Acoustic absorption and transmission loss were measured for different configurations based on the investigated materials. Measurements were carried out by impedance tube method. Results show that the best performing panel is the one constituted by SN and LDP layers.
