Advancements in Acoustic Topology Optimization
The design of products in the audio industry is to a large extent done via a combination of prior knowledge and trial-and-error. Such an approach will sometimes be seen described as an ‘optimization’ of said products, but we will here focus on the formal mathematical approach of ... Read More
Evaluation of the Ray-Tracing and Pressure Acoustic Solvers for Audio Simulations in a Vehicle
For automotive applications, acoustical simulation methods are used to optimize the position and orientation of the loudspeakers to get the best audio system performance. The goal of the presented paper is to evaluate the accuracy of the Pressure Acoustics interface (Finite Element, wave ... Read More
Acoustic-Mechanic Modeling of Polydimethylsiloxane in the MHz Regime for Metamaterials Applications
Polydimethylsiloxane (PDMS) is a biocompatible material widely used in biomedical applications such as implantable sensors. A realistic modeling of PDMS in acoustic-mechanic simulation is useful especially for medical applications which use ultrasonic waves as interrogation source. ... Read More
Acoustic Propagation Model in 3D of Dolphin Echolocation Formation Inside Head Tissues
Introduction The echolocation signals of dolphins consist of forward-projected sound pulses that reflect off objects and are used to probe underwater surroundings. Despite rigorous studies of dolphin echolocation, there remain questions about how echolocation sounds are produced and ... Read More

The COMSOL® app library of the Technical University of Munich is a collection of applications for simulating acoustic phenomena. They are used in the teaching of acoustics to visually represent fundamental vibrational aspects and provide learners with a visual understanding. In the ... Read More
Modeling of Acoustically Induced Rapid Mixing Processes in Microchannels Using Acoustic Streaming
Technical advancements in miniaturization in the last decades have, among others, brought forth the technology of so called “Lab-on-a-Chip” (LOC) systems. These systems provide the possibility to automate and accelerate certain laboratory processes, e.g., biomedical diagnostics, on the ... Read More
Complete Design of a High Power Ultrasonic Flow-Cell Reactor with Special Air Cooling System
Ultrasonic flow-cell reactors are used for many industrial applications, where fluid substrate is sonicated in a small region, where very high ultrasonic acoustic power is present. The electromechanical transducer (converter) that drive the sonotrode inside the flow-cell is designed in ... Read More
Design of One-Dimensional Acoustic Meta-Filter with Multiple Resonators
New design structure for generating and tuning the multi-bands of negative modulus is presented by introducing metamaterial concept. To effectively achieve selective noise reduction and sound transmission, acoustic metamaterial consisted of arrayed multiple resonators with extended necks ... Read More
Simulation of a Hybrid (Active/Passive) Acoustic Measurement Room
The ideal way to measure the acoustic performance of heavy items such as vehicles or machines is in a semi-anechoic chamber, i.e. in an environment with no reflections except from the solid floor where the noise source is standing. To accurately measure low frequencies down to 20 Hz ... Read More
