The present invention discloses a soundproof cabin of a turbine engine. The soundproof cabin is sleeved on the turbine engine. The soundproof cabin includes a cabin body, an intake noise reduction unit and a ventilation noise reduction unit, wherein the intake noise reduction unit and the ventilation noise reduction unit are disposed on the cabin body, the surrounding of which is filled with soundproof materials, the intake noise reduction unit is used to reduce the induction noise of the turbine engine, the ventilation noise reduction unit is used to reduce the noise of the ventilation system of the turbine engine. Beneficial effects: an intake noise reduction unit is disposed at an air inlet of the turbine engine to reduce the induction noise of the turbine engine; a ventilation noise reduction unit is disposed on the transmission direction of the turbine engine to reduce the ventilation and cooling noise of the turbine engine; the surrounding of the turbine engine is filled with soundproof materials to achieve the overall noise reduction around the turbine engine.
