$\star \text{ }\underline{\text{Boundary Element Analysis (BEA)}} $ $\rightarrow$ It is used to predict noise characteristics on various mechanical systems. $\rightarrow$ When coupled with FEA, BEA is very useful in determining the acoustical effects of structural design modification. $\phantom{\text{CFD softwares}}$ $\text{BEA softwares}$ 1. Scuff EM $\phantom{\text{CFD softwares}}$ $\text{Why should BEA be used?}$ $\rightarrow$ It allows the customer to predict the acoustical performance of your concept before production. $\rightarrow$ This allows for design modifications to improve the overall acoustic characteristics without costly laboratory testing and various prototypes from having to be fabricated. $\rightarrow$ BEA is used to predict and optimize the noise, vibration, and harshness (NVH) characteristics os various structures from small components to full size powertrain systems and interior vehicle cabs. $\phantom{\text{CFD softwares}}$ $\text{BEA capabilities}$ $\star$ sound pressure analysis $\star$ sound intensity analysis $\star$ sound power predictions $\star$ radiation efficiency analysis
