Multiscale and Multiphysics Modeling of an Adaptive Material for Sound Absorption

T. G. Zielinski [1], K. C. Opiela [1],
[1] Institute of Fundamental Technological Research of the Polish Academy of Sciences, Warsaw, Poland

A concept of an adaptive sound absorbing material is proposed and investigated numerically using the COMSOL Multiphysics® Software suitable for the required advanced dual-scale modelling which involves solution of various problems of physics at the microscopic and macroscopic levels. A ... Read More

Structural Mechanics, Acoustics Module - Numerical Study of Loudspeaker Diaphragm Geometry

A. Mageswaran [1],
[1] DTU-Technical University of Denmark, Denmark

The study of loudspeaker diaphragm geometry is aimed to focus on how does the distribution of mass in the radial direction changes the ‘dynamic and acoustic response’ of the diaphragm. The geometry is subjected to concentrating the mass by changing the shape of our interest in a 2D ... Read More

Photoacoustic Modeling Using Amplitude Mode Expansion Method in a Multi-Scale T-cell Resonator

S. El-Busaidy [1], B. Baumann [1], M. Wolff [1], L. Duggen [2],
[1] Hamburg University of Applied Sciences, Germany
[2] University of Southern Denmark, Denmark

The photoacoustic (PA) effect consisting of the generation of an acoustic signal based on the absorption of light has already demonstrated its potential for various spectroscopic applications for both gaseous and solid samples. The signal produced during photoacoustic spectroscopy (PAS) ... Read More

Simulation-Led Design to Optimize Innovative Acoustic Phantom and Ice Catheter Calibration Method

E. Adawi [1],
[1] Biosense Webster, Inc., Kibbutz Shefayim, Israel

Intracardiac Echocardiography (ICE) ultrasound imaging of cardiac cavities is a known diagnostic and monitoring technique, used during interventional cardiology and electrophysiology procedures. The SOUNDSTAR® Catheter, manufactured by Biosense Webster, Inc., enables locating the ... Read More

Iterative Electric Potential Adjustment of Damaged Naval Vessels Using the Onboard ICCP-System

C. Thiel [1], K. Neumann [1], C. Broecheler [1], F. Ludwar [2], A. Rennings [1], J. Doose [2], D. Erni [1],
[1] General and Theoretical Electrical Engineering (ATE), University of Duisburg-Essen, and CENIDE – Center for Nanointegration Duisburg-Essen, Duisburg, Germany
[2] Technical Center for Ships and Naval Weapons, Naval Technology and Research (WTD 71), Eckernförde, Germany

Naval vessels involuntary communicate with their surrounding environment via different signatures, which can be separated in acoustic, electric, magnetic, seismic and pressure signatures. The electric signature, also known as Underwater Electric Potential (UEP)-Signature is mainly caused ... Read More

Reducing Loudspeaker Systems Panel Vibrations

D. Cinanni [1],
[1] ASK Industries Spa, subject to direction and coordination of JVCKENWOOD Corporation, Italy

One of the main design questions in loudspeaker enclosures concern vibrations reduction. An ideal cabinet would be infinitely rigid, so a section of an engineer work is focused on this goal. Solutions depend by loudspeaker system audio field: Line Arrays, Automotive environments or hi ... Read More

Empirical Verification of COMSOL® - Simulation of Resonance Frequency of an Archimedean Spiral Coil

M. P. Adams [1], K. P. Koch [1],
[1] Hochschule Trier, Trier, Rhineland Palatinate, Germany

An simple analytical model for the calculation of the resonance frequency of coils typical consists of a network of inductance, capacitance and resistance. Calculating these three parameters based on spatial geometry is not easy in most cases. The finite element method as used in COMSOL ... Read More

Modeling of Airborne Transmission in Floor System Including Flanking Transmission

D. Bard [1], M. Kuster [1],
[1] Kuster + Partner AG, Switzerland

Predicting vibroacoustic performance in buildings in terms of sound insulation is a challenging task. As of today, no widespread standardised accurate method for predicting either impact or airborne sound insulation has been established. Rather, several software relying in the analytical ...

Acoustic Modeling of a “Minute Repeater”

S. Charron [1],
[1] Intermezzi ingénierie acoustique, Paris, France

The project was ordered by a Swiss watchmaker. The aim was to modelize and optimize the acoustic of a minute repeater on one of the high range item made by the watchmaker. Therefore we based our work on a simplified geometry made by Creo. The mesh model includes the gongs, the bottom ... Read More

Acoustic metamaterial: from conception to auralization

C. Lagarrigue, D. Lecoq
Metacoustic - www.metacoustic.com, Le Mans, France

Metamaterials have become a very hot topic in scientific publications, especially in Acoustics. In 2018, nearly 3,000 publications can be already found about acoustic metamaterials (source: Google Scholar). But how many industrial applications? Not that much because they are often ... Read More
