COMSOL Day: Acoustics
See what is possible with multiphysics simulation
Join us for a full-day online event with a special focus on acoustics. You will have the opportunity to meet with COMSOL technical staff and customers from around the world, engage in product demonstrations, and gain insight into upcoming projects and focuses within acoustics research and industry.
Topics include the analysis of loudspeakers, ultrasound and non-destructive testing (NDT), microacoustics, room acoustics, vibrations, as well as convected acoustics. We will also address topics like optimization, meshing, and solving of large acoustic models. During the presentations you will be encouraged to ask questions. Engineers from COMSOL will be able to answer and present best practices.
Feel free to invite your colleagues. View the schedule below and register for free today!
To start, we will briefly discuss the format of the day and go over the logistics for using GoToWebinar.
During this session, you will get an introduction to the latest news and trends in acoustics simulation. We will also briefly discuss some of the future developments and ideas for the Acoustics Module.
Acoustic propagation in structures with submillimeter physical features is common in the components of consumer products like mobile devices, protective grills of loudspeakers, hearing aids, and perforates used in mufflers and sound insulation. To model this accurately, you need to include thermoviscous losses in your definition of the physics. In this session, you will be introduced to modeling techniques used to capture these effects and how to model nonlinear effects in microacoustics systems.
In this session, we will introduce key features within COMSOL Multiphysics® and the Acoustics Module and discuss how to solve the acoustic wave equation in order to model sound generation, propagation, absorption, and attenuation. The key features will be demonstrated by building a simple model, from applying the physics and properties of the system to the different ways to postprocess the results.
Noise and vibration analysis covers areas from ground-borne noise and noise generated by machinery to the analysis of feedback in electroacoustics applications. The physics involved in such applications deal with the combined propagation and interaction of elastic waves in structures and pressure waves in fluids. In this session, you will learn how to model these phenomena through several examples and demonstrations.
The analysis of acoustic phenomena in the presence of background mean flow is often referred to as convected acoustics or flow-borne noise. Applications include jet engine noise, mufflers, and perforates, all including the presence of a background flow. This session will introduce the aeroacoustics capabilities of COMSOL Multiphysics® and demonstrate examples of convected acoustics.
Join us for a discussion with leading industry experts on how they are using simulation in general, and COMSOL Multiphysics® in particular, in the development of innovative audio products.

A large number of applications involve the modeling of ultrasonic wave propagation in fluids and solids. This includes nondestructive testing (NDT), flowmeters, and ultrasound equipment in medical processes. During this session, you will be introduced to strategies for modeling such phenomena in COMSOL Multiphysics®, from the behavior of piezoelectric transducers to the nonlinear propagation of finite-amplitude ultrasonic waves in fluids.
Acoustic propagation in rooms, halls, car cabins, and other enclosed yet definitive spaces falls within the field of room acoustics. In this session, you will learn how acoustic behavior and response from the features in a room can be modeled in COMSOL Multiphysics® using both ray tracing and full-wave models, in some cases combined with each other. This feature is useful when defining submodels of, for example, a treated wall or absorber, in order to compute the angle-dependent absorption, which is then used in a ray tracing model for the room as a whole.
The design and optimization of loudspeakers is a challenging multiphysics problem that requires various numerical approaches, depending on the accuracy required and the complexity of the system. This can range from lumped electroacoustics models in the frequency domain to nonlinear transient analyses of total harmonic distortion. In this session, you will receive insight into the modeling techniques available for loudspeaker simulations as well as appropriate postprocessing tools that provide you with a fully virtual testing environment.
When solving large acoustics models, it can be beneficial to tune the solvers by considering performance, stability, and memory consumption. A good strategy with respect to meshing and other modeling options is also important. This session will illustrate the process, from choosing one of the predefined solver suggestions in COMSOL Multiphysics® as a starting point to determining how the solver settings can be manipulated and tuned for robust modeling of acoustics phenomena.
