The mid-frequency noise in a tractor cab is predicted, the FE-SEA hybrid model of tractor cab is established, the cab structure modal density, internal loss factor and coupling loss factor are obtained by theoretical calculation and test method, and the finite element-statistical energy analysis is simulated after loading vibration and noise excitation. Comparing the cab acoustic pressure level obtained by the simulation with the measured data, the analysis and comparison show that the result of the model using FE-SEA hybrid method in the mid-band is highly fitting with the test value, and the prediction absolute error is less than 2dB, which can be used for further analysis.
