Thermal and Sound Insulation Properties of Organic Biocomposite Mixtures. [PDF]
Polymers (Basel)Sustainable building materials with excellent thermal stability and sound insulation are crucial for eco-friendly construction. This study investigates biocomposites made from cellulose pulp reinforced with beeswax, fir resin, and natural fillers like horsetail, rice flour, and fir needles. Eight formulations were obtained, and their thermal resistance,

Sound insulation properties of a spherical structure of subwavelength size [PDF]
AIP Advances, 2019 Because of the limited sound insulation provided by a single material, it is common to use multiple layers of materials to improve the effects of sound insulation, but multiple materials increase the size of the model.

Sound insulation properties of sandwich panels
IOP Conference Series: Materials Science and Engineering, 2020 Abstract The sound transmission via building enclosures of finite dimensions has a resonant and inertial components. The resonant transmission of sound takes place in the mode of self-induced vibrations depending on the degree of self-coordination of its own wave field with sound fields present in the air on both sides of the enclosure ...

Research on the Sound Insulation Properties of Membrane-type Acoustic Metamaterials [PDF]
E3S Web of Conferences, 2021 Low- and medium-frequency noise from ship cabins is difficult to control effectively. Excessive noise can seriously affect the acoustic stealth performance of ships. A novel membrane-type acoustic metamaterial is proposed in this paper with light weight and good sound insulation performance at low frequencies.
