[0016] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0017] like Figure 1 and Figure 2 As shown, the utility model proposes a sound-absorbing ventilation device for a marine engineering living cabin, comprising a ventilation pipe 1, a sound-absorbing structure 2 and an echo structure 3, the sound-absorbing structure 2 is arranged on the ventilation pipe 1, the echo structure 3 is arranged on the sound-absorbing structure 2, the sound-absorbing structure 2 comprises a sound-absorbing panel 4, an air flow channel 6 and a sound-absorbing hole 7, the sound-absorbing panel 4 is arranged on the inner wall of the ventilation pipe 1, the interior of the ventilation pipe 1 is covered with the sound-absorbing panel 4, the air flow channel 6 is arranged on the inner wall of the sound-absorbing panel 4, and the sound-absorbing hole 7 runs through the air flow channel 6.

[0018] like Figure 2 and Figure 3As shown, the echo structure 3 includes an echo board 8, an echo bowl 9, a fixing seat 10, an echo bowl 11 and an echo board 12.
