Ventilation system noise calculation method, system and device and storage medium

The invention belongs to the technical field of ship design, and provides a ventilation system noise calculation method, system and device and a storage medium, an established ventilation system model is obtained, system model parameters are input into the ventilation system model, a mathematical model of the ventilation system model is established, the mathematical model is solved to obtain pressure drop data and noise data, and the noise data is calculated. Adjusting the parameters of the ventilation system model and repeating the steps until the pressure drop data of the ventilation system model meets the pressure drop balance condition, and outputting the noise data of the ventilation system model meeting the pressure drop balance condition, thereby effectively avoiding the problem of repeated modeling in the noise calculation of the ship ventilation system, and improving the noise calculation accuracy. Data transmission between the CAD design model and the CAE calculation model is reduced, and the design
