The invention discloses a traffic noise dynamic simulation method and device for a roundabout and a storage medium, and the method comprises the steps: constructing a cellular automaton traffic flow model and a vehicle noise emission probability model of a two-lane roundabout, the cellular automaton traffic flow model is used for simulating the traffic condition of the roundabout, and the vehicle noise emission probability model is used for generating a vehicle noise emission probability model of the two-lane roundabout; the vehicle noise emission probability model is used for calculating real-time noise emission information of each vehicle; integrating the vehicle noise emission probability model into a cellular automaton traffic flow model, and dynamically simulating traffic noise of the roundabout; and determining a noise index according to the dynamic simulation result of the traffic noise. The method improves the calculation speed, reduces the complexity, and can be widely applied to the technical field of data processing.
