cal acoustic methods, the finite element method (FEM) offers an advantageous combination of modeling flexibility, computational efficiency and results accuracy. Acoustical FEM can be easily coupled with structural FEM, which is already well-known to most structural analysts. The acoustical and structural coupling in the

2019-10-24 · FEM can be used to study the acoustic behavior of MEMS devices. However, using FEM simulations for the calculations of the total response of the system is computationally expensive, time consuming, and inconvenient. Hence, analytical formulas are desirable to use in calculations for optimizing the MEMS.

The field of acoustics has been no exception. Currently, the standard finite element method (FEM) is still the most reliable and widely-used numerical tool in simulating acoustic scatting with many meaningful investigations can be found in literature reviews,,. Finite element method 2 Acoustic wave equation in 1D How do we solve a time-dependent problem such as the acoustic wave equation? where v is the wave speed. using the same ideas as before we multiply this equation with .
