Full Acoustic Room Impulse Response of a Small Smart Speaker

July 7, 2023

The acoustic response of a small smart speaker can be modeled using the built-in hybrid FEM–ray coupling functionality in the COMSOL Multiphysics® software. Learn more here.

The Octave Band Plot for Acoustics Simulation

September 9, 2022

The Octave Band plot provides an easy and flexible way to represent any frequency response, transfer function, sensitivity curve, transmission loss, or insertion loss in your acoustics analyses.

Modeling Sound Transmission Loss Through a Concrete Wall

October 7, 2020

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

May 28, 2020

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

August 30, 2019

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

April 25, 2019

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

April 5, 2019

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

March 19, 2018

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).
