The invention relates to a vehicle cab sound quality evaluation method of a PSO optimization delay operator model, the PSO algorithm with the global optimization capability is adopted, so that the initial weight and the threshold value of the PSO algorithm optimization network are within a small range at the beginning, the subsequent training cost is reduced, and the function of improving the evaluation precision of the sound quality is achieved. A sound quality prediction model containing the delay operator has the advantages that the convergence speed is high, the training time is short, historical learning samples can be effectively utilized, the accuracy of the evaluation model is high, and the occurrence of local minimum values can be effectively inhibited. According to the method, the problems that the training time complexity of a traditional sound quality evaluation model is large, and the sound quality prediction precision is low due to the fact that a certain minimum value cannot be automatically fo
