An aluminum (Al) honeycomb was used to protect the insulation materials\' structural integrity and ensure the homogeneous distribution of sound waves.
This paper reports a significant improvement of the sound absorption in a broad frequency range when one of the surface sheets of honeycomb panels is micro-perforated.
Lin et al. [20] developed a sandwich panel composed of 7D polyethylene terephthalate (PET), thermoplastic polyurethane (TPU) honeycomb meshes and
The effect of dislocation arrangement and diatom mud coating on the sound absorption performance of low-frequency noise of sandwich panels is analysed
Abstrac The purpose of the research is to assess the sound absorption performance (SAP) of acoustic metamaterials made of double-layer Nomex honeycomb structures in
The micro-perforated honeycomb sandwich panel has poor sound absorption frequency at medium and low frequencies. In this paper, a dislocation honeycomb structure with
Based on these findings, we designed a novel aluminum-rubber composite structure possessing enhanced low-frequency absorption, high resistance to
An aluminum (Al) honeycomb was used to protect the insulation materials\' structural integrity and ensure the homogeneous distribution of sound waves.
As part of a complete range of aluminium honeycomb lightweight panels, AYRES offer comprehensive acoustic solutions which combine sound absorption with attractive
This paper demonstrates a design of a composite honeycomb metasurface panel that can achieve 90% sound absorption from 600 to 1000 Hz with a
An aluminum (Al) honeycomb was used to protect the insulation materials\' structural integrity and ensure the homogeneous distribution of sound waves. The effect of density differences on sound insulation values was investigated. The mechanical properties of sandwich structures were determined using compression and three-point bending
This paper reports a significant improvement of sound absorption in a broad frequency range when one of surface sheets of honeycomb panels is micro-perforated. Acoustical analysis and test have been used to select
Lin et al. [20] developed a sandwich panel composed of 7D polyethylene terephthalate (PET), thermoplastic polyurethane (TPU) honeycomb meshes and polyurethane (PU) foam. The results show that sound absorption coefficient (SAC) of the sample in the frequency range of 2000–4000 Hz is greater than
The effect of dislocation arrangement and diatom mud coating on the sound absorption performance of low-frequency noise of sandwich panels is analysed from the parameters of
Abstrac The purpose of the research is to assess the sound absorption performance (SAP) of acoustic metamaterials made of double-layer Nomex honeycomb structures in which a micro-orifice corresponds to a honeycomb
The micro-perforated honeycomb sandwich panel has poor sound absorption frequency at medium and low frequencies. In this paper, a dislocation honeycomb structure with built-in diatom mud coating is designed, which can im-prove the acoustic performance of the sandwich structure at medium and low frequency
Based on these findings, we designed a novel aluminum-rubber composite structure possessing enhanced low-frequency absorption, high resistance to shear load, normal compression, and
An aluminum (Al) honeycomb was used to protect the insulation materials\' structural integrity and ensure the homogeneous distribution of sound waves. The effect of density
As part of a complete range of aluminium honeycomb lightweight panels, AYRES offer comprehensive acoustic solutions which combine sound absorption with attractive design options, in a fibre-free and lightweight
This paper demonstrates a design of a composite honeycomb metasurface panel that can achieve 90% sound absorption from 600 to 1000 Hz with a thickness less than 30 mm. The panel is comprised of periodically and horizontally arranged honeycomb “supercells” which consist of unit cells of different geometric parameters (pore
