Research on the Design of Sound Insulation Performance of Isolating-sound and decoupled tile Based on Local Resonance Membrane Material

Abstract: In order to enhance the acoustic stealth performance of the underwater vehicle, we combine the resonance sound absorption and vibration suppression performance of the sound-absorption coating and the low frequency sound insulation performance of the local resonance membrane material, a new type of isolating-sound and decoupled tile with low-frequency sound insulation, sound absorption and vibration suppression performance is designed, and an acoustic enclosure composed of isolating-sound and decoupled tile is … Show more

“…is is because MMH improves the compatibility in polymer matrix and can effectively improve the tensile strength of PS composite. Similar to tensile strength, the change trend of elongation at break with the increase of MH is the same as that of tensile strength, reaching the maximum value of 87% in PS-MMH-3, indicating that PS-MMH-3 has high extensibility and can be used in building materials [4,19].…”

“…At present, the insulation board is not suitable for the insulation of irregular building parts, and its application is limited due to complex construction and high comprehensive cost. However, as a new type of building material, the thermal insulation masonry mortar or block has the advantages of light weight, low thermal conductivity, low comprehensive cost, low water absorption, and convenient construction, which can overcome many shortcomings of thermal insulation board [4]. It can be seen from Figure 1 that the real significance of wall material innovation is to realize the direct self-insulation of building masonry mortar or block as soon as possible.…”
