[0002] A shipping container is a set of tools that can carry packaged or unpackaged goods for transportation and is easy to load and unload using mechanical equipment. A container generator room is a modular power solution that uses a standardized container as a carrier and integrates a diesel generator set, auxiliary system and intelligent control module, combining high efficiency and environmental adaptability.

[0003] The high temperatures generated by the operation of equipment inside container generator rooms necessitate opening windows on the container surface for heat dissipation. However, this compromises the overall sound insulation of the container, increases noise in the windowed areas, and consequently affects the noise reduction and sound attenuation effects of surrounding container generator rooms.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This application achieves noise reduction by setting up a vacuum area around the ventilation duct to block part of the sound wave propagation medium.

[0022] Air enters the housing 1 through the ventilation duct 4 at the air inlet 2, and the air inside the housing 1 is discharged through the ventilation duct 4 at the air outlet 3. When the sound passes through the ventilation duct 4, it will be silenced by the honeycomb panel 7 area. After the silencing is completed, it will be silenced again by the S-shaped cavity composed of various silencing baffles 6.

[0031] The staggered arrangement of rock wool boards and sound-absorbing boards can cover the gaps between adjacent sound-absorbing boards, thereby improving the sound insulation or sound absorption effect of rock wool layer 10 and composite sound-absorbing layer 11;

[0032] The rock wool layer 10 is made of rock wool, and the composite sound-absorbing layer 11 is a composite material that combines multiple layers of materials, including calcium silicate board, glass wool, and damping sound insulation board, to achieve noise reduction.
