| Abstract: | The panel acoustic contribution analysis method based on direct boundary element method is studied aiming at reducing the noise of closed tractor cab. Taking a tractor cab modal as example, the sound pressure level (SPL) at driver's right ear is determined and the panel acoustic contribution (PACA) to the field point is analyzed. The analysis result is explained using acoustic transfer vector (ATV) and structure vibration velocity result from previous analysis. Based on the analysis, structure modify target... |
