Modeling Sound Transmission Loss Through a Concrete Wall
The sound loss transmission (STL) through a building component is the logarithmic ratio between the total incident power on the structure relative to the total transmitted power.
Introduction to the Elastic Waves, Time Explicit Interface
From nondestructive testing to seismic wave propagation in soil and rock, there are many application areas that involve the propagation of elastic waves in solids and vibrations in structures.
How to Use Solver Suggestions in Acoustics Modeling
When you model large, industry-scale acoustics, ever find it challenging to efficiently solve the problem with the hardware at hand? Enter the solver suggestions in COMSOL Multiphysics®.
Using the Port Boundary Condition in Acoustic Waveguide Models
By combining several Port boundary conditions, you can easily compute the transmission and insertion loss in exhaust and muffler systems. See more benefits of this feature for acoustics modeling.
Fine-Tuning the Design of Piezoelectric Transducers with Simulation
A variety of use cases and a variety of physics: Piezoelectric transducer designs need to account for electric currents, pressure acoustics, stress-strain, and acoustic-structure interaction.
How to Use the Boundary Element Method in Acoustics Modeling
Learn advantages and strategies for using the boundary element method (BEM) for acoustics modeling. Plus, we go over a hybrid approach that combines BEM with the finite element method (FEM).
Modeling Aeroacoustics with the Linearized Navier-Stokes Equations
Get a comprehensive introduction to aeroacoustics modeling, as well as the linearized Navier–Stokes equations and how to implement them in COMSOL Multiphysics®.
Using the Discontinuous Galerkin Method to Model Linear Ultrasound
You can easily model acoustically large problems, like linear ultrasound, with a predefined physics interface that uses a memory-efficient approach called the discontinuous Galerkin method.
