SOUND ABSORBING SANDWICH PLATE Russian patent published in 2019 - IPC G10K11/168 B32B7/02 E04F13/08 E04B1/86 B60R13/08 

FIELD: physics.

SUBSTANCE: invention relates to materials for sound and heat insulation and relates to a sound absorbing sandwich plate. Said plate for attachment to structural component (40) has first layer (12) and second layer (22) associated with first layer (12), moreover, first layer (12) is located on the side of second layer (22) opposite to structural component (40), on the plane along second layer (22) at least one fastener (30) is provided, which has a plurality of engaging elements (38), which can engage with second layer (22), moreover, second layer (22) with the help of fasteners (30) is attached to surface (42) of structural component (40), moreover, first layer (12) has a higher specific gravity and / or a higher density compared to second layer (22).

EFFECT: invention provides for the creation of a plate with effective thermal insulation in combination with high performance relating to sound insulation or noise absorption.
