Description

Technical Field

[0002] Traditional diesel generator room sound absorption structures mainly use two types: porous sound absorption panels and resonant sound absorption panels. Porous sound absorption panels are made of glass fiber, polyester fiber, mineral wool and other materials. They mainly absorb sound by converting sound energy into heat energy when sound waves propagate in the internal pores of the material and encountering friction and resistance. Resonant sound absorption structures, on the other hand, use specially designed resonant cavities to make sound waves resonate at a specific frequency, converting sound energy into mechanical energy to achieve the effect of sound absorption.

[0003] However, due to the poor durability of porous sound-absorbing panels and resonant sound-absorbing panels, the sound absorption performance is not ideal and long-lasting. Utility Model Content

[0054] Of course, in other embodiments, the cross-sections of the groove 31 and the protrusion 32 may also be rectangular or other special shapes.

[0055] In one embodiment, the number of calcium silicate boards 1 is two, and the two calcium silicate boards 1 are stacked together in sequence along the thickness direction of the sound-absorbing and sound-insulating integrated structure.
