Analyzing Hearing Aid Receivers with Lumped-Parameter Modeling

March 17, 2017

Modeling complete hearing aid systems is extremely computationally expensive. Enter lumped-parameter modeling, which enables you to couple a system component to a test setup for validation.

Using the Discontinuous Galerkin Method to Model Linear Ultrasound

January 26, 2017

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.

Keynote Video: Locating Leaks in Pipe Networks with a Simulation App

January 16, 2017

Sebastien Perrier of Echologics discusses a simulation application used to locate leaks in underground pipe networks in his keynote presentation at the COMSOL Conference 2016 Boston.

How to Model an Anechoic Coating

January 5, 2017

Modeling an anechoic coating involves finding the smallest unit cell, truncating the geometry, and analyzing the wave diffration. The COMSOL® software includes predefined interfaces to do so.

Using the Domain Decomposition Solver for Thermoviscous Acoustics

November 25, 2016

Learn how to use the Domain Decomposition solver, a memory-efficient iterative algorithm with inherent parallelism on the geometric level, in COMSOL Multiphysics®.

How to Use Acoustic Topology Optimization in Your Simulation Studies

November 3, 2016

Today, guest blogger René Christensen of GN Hearing discusses the importance of acoustic topology optimization and how to apply it in COMSOL Multiphysics. Topology optimization is a powerful tool that enables engineers to find optimal solutions to problems related to their applications. Here, we’ll take a closer look at topology optimization as it relates to acoustics and how we optimally distribute acoustic media to obtain a desired response. Several examples will further illustrate the potential of this optimization technique.

Optimizing a Tunable Organ Pipe for Ocean Acoustic Tomography

November 1, 2016

Read about a scientist from Teledyne Marine Systems who used simulation to improve a tunable organ pipe design and then compared the results to experimental tests.

Efficiently Calculating the Acoustic Transfer Impedance of a Perforate

September 29, 2016

Learn how to efficiently calculate the acoustic transfer impedance of a perforate in COMSOL Multiphysics®. (Hint: It involves applying a semitransparent boundary to the model.)
