| Abstract: |
| The sound insulation analysis model is presented in terms of sound insulation theory and practical engineering for the sound insulation problem of flying thin shell with complicated configration and special organization. It is compared with the measurement of the simulated shell by calculation. The results showed that the presented sound insulation analytic method and the model are correct and feasible The calculation can be used to evaluate the sound insulation ability for flying structure. |
