Methods for noise reduction at a smart gas field station, Internet of Things (IoT) systems, and storage media are provided. The method may include obtaining relevant data of a target field station, the relevant data including at least one of operating data of the target field station, noise data of the target field station, and a pressure regulation parameter of an associated field station; predicting, based on the relevant data, noise enhancement data of the target field station for at least one future period; and determining a noise reduction control parameter based on the noise enhancement data and the pressure regulation parameter. The IoT system may include a smart gas user platform, a smart gas service platform, a smart gas safety management platform, a smart gas pipeline network equipment sensing network platform, and a smart gas pipeline network equipment object platform.
