Description

Technical Field

[0001] The utility model relates to the technical field of composite sound insulation structures, and more specifically, to a non-fibrous material composite sound insulation structure. Background Technique

[0002] In order to implement environmental protection requirements, noise can be reduced. There are many ways to reduce noise, and the non-fibrous material composite sound insulation structure is one of the ways to reduce noise and isolate sound.

[0003] After retrieval, a broadband composite sound insulation structure with the existing publication number CN219143788U includes a first sound insulation mechanism and a second sound insulation mechanism. The first sound insulation mechanism and the second sound insulation mechanism are arranged opposite to each other and a closed air layer is formed between them. Through the settings of the first sound insulation mechanism, the second sound insulation mechanism and the air layer, effective reduction and suppression effects can be achieved on broadband noises such as high-frequency, medium-frequency and low-frequency noises. By setting the first sound insulation board and the second sound insulation board, the pollution of the external environment to the first sound insulation layer and the second sound insulation layer can be reduced while reducing noise.

[0004] For common non-fibrous material composite sound insulation structures, when sound insulation treatment is carried out, the sound cannot be effectively reduced step by step, thus reducing the sound insulation performance. Therefore, we propose a non-fibrous material composite sound insulation structure to solve the above existing problems. Content of the Utility Model
