The ITA-Toolbox COMSOL interface

01. Juni 2021 | von

Acoustic simulations become a more and more important toolset for industry and research. For a few years now, our institute uses COMSOL Multiphysics for numerical simulations, e.g. FEM and BEM, in various fields of acoustics. For proper processing of simulation results, we usually rely on MATLAB and the ITA-Toolbox. Although COMSOL provides a MATLAB interface (LiveLink), using this for advanced processing is not straightforward. With this in mind, a user-friendly interface between the ITA-Toolbox and COMSOL was designed.

Key features

  • Starting the COMSOL server and connecting Matlab
  • A rich class structure representing a COMSOL model and its model nodes (geometry, physics, …)
  • Evaluation of FEM / BEM results at arbitrary points using the itaResult format without writing the results to hard disk
  • Quickly applying complex-valued, frequency-dependent data to COMSOL model (itaResult -> COMSOL interpolation)

Class structure of the ITA-Toolbox COMSOL interface

The class structure makes the usage of this interface intuitive and easily extendable. Similar to the actual COMSOL model, the itaComsolModel class contains nodes representing the geometry, physics, study and so on. Each node comes with functions to interact with the respective node. However, the current toolset also allows applying significant changes your model using a single line of Matlab code. For example, the user can apply a user-defined impedance to a pre-defined boundary selection or create a monopole source with a user-defined frequency response. In this case, multiple of those nodes are modified (e.g. geometry and physics).

If you are interested, the interface is part of the ITA-Toolbox, that can be downloaded or cloned from our Git repository. The related files can be found in the folder “ITA-Toolbox\applications\SoundFieldSimulation\Comsol\”. This also contains a set of small demos for getting started.

Promotionsprüfung Dipl.-Ing. Lukas Aspöck

17. Juli 2020 | von

Am 10. Juli 2020 hat Herr Lukas Aspöck seine mündliche Promotionsprüfung erfolgreich abgeschlossen.

Herr Aspöck promovierte über das Thema:
„Validation of room acoustic simulation models“

Abstract:

Already in ancient times, the goal existed to design appropriate environments to transport acoustic signals from a sound source to an audience. Strongly connected to this is the interest to understand room acoustic effects and, in the best case, to accurately predict them. This is of particular relevance today in prestigious projects such as the construction of concert halls, but is also of great importance in everyday life, for example in public buildings. Room acoustic simulations based on the concepts of geometric acoustics have been developed for such purposes for more than 50 years and have been extensively investigated. However, there is still insufficient knowledge about the uncertainty and validity of the results of the room acoustic simulations used today. In addition, many highly simplified simulation models are often used without questioning the validity of the results.

In order to offer developers and researchers a possibility to comprehensively validate the results of their room acoustic simulation, a database with eleven different acoustic scenes was developed, documented and published. The scenes cover both simple environments, where individual acoustic effects such as reflection or diffraction are isolated, and complex spatial situations such as a concert hall. In addition to a detailed description and the definition of input data, acoustic measurements were carried out for all scenes, which serve as reference for the simulations.

Furthermore, a study is presented which was designed following the concept of three previously conducted round robin experiments. Here, the simulation results of up to six participants, who were not informed about measurement results in advance, are compared with each other and with the results of the corresponding measurements. The evaluation of the results for the simple scenes reveals various weaknesses of the geometric acoustics, but in the case of the complex scenes it nonetheless shows acceptable results in the medium frequency range. In further investigations it was determined how much room acoustic simulation results deviate from measurements if the user knows the measurement results beforehand and input data of the simulation is adjusted manually or systematically. From these results it can be concluded which deviations from actual, measured values can be expected in the room acoustic simulation of both unknown and known rooms. Furthermore, this work provides a basis for improvements in the field of geometrical acoustics simulation models and with respect to the determination and selection of correct input data for the simulation.

Promotionsprüfung Josefa Oberem, M.Sc.

27. Januar 2020 | von

Am 24. Januar 2020 hat FrauJosefa Oberem, M.Sc, ihre mündliche Promotionsprüfung erfolgreich abgeschlossen.

Frau Oberem promovierte über das Thema:
„Examining auditory selective attention: From dichotic towards realistic environments“

Abstract:

The aim of the present thesis is to examine the cognitive control mechanisms underlying auditory selective attention by considering the influence of variables that increase the complexity of an auditory scene. Therefore, technical aspects such as dynamic binaural hearing, room acoustics and head movements as well as those that influence the efficiency of cognitive processing are taken into account. Step-wise a well-established dichotic-listening paradigm is extended into a “realistic” spatial listening paradigm.
Conducted empirical surveys are based on a dichotic-listening paradigm examining the intentional switching of auditory selective attention. Spoken phrases are simultaneously presented by two speakers to participants from two of eight azimuthal positions. The stimuli are phrases that consist of a single digit (1 to 9, excluding 5), in some experiments followed by either the German direction “UP” or “DOWN”. A visual cue indicates the target’s spatial position, prior to auditory stimulus onset. Afterwards, participants are asked to identify whether the target number is arithmetically smaller or greater than five and to categorize the direction. Reaction time and accuracy are performance measures. Differences of performance measures between the repetition of the target’s spatial position and the related switch (switch costs) describe the loss of efficiency associated with redirecting attention from one target’s location to another. To examine whether the irrelevant auditory information is decoded, interference in the processing of task-relevant and task-irrelevant information is created in the paradigm.
To study the binaural effects in the intentional switching of auditory selective attention, the dichotic-listening paradigm is gradually extended towards a binaural-listening paradigm representing complex dynamic acoustic scenes in the present thesis. In order to realize the extension of the paradigm towards a realistic scene various technical methods and tools need to be applied. As the listening paradigm is step-wise broadened towards realistic scenes the technical methods and tools are assessed with respect to the collected empirical results.
Using the binaural-listening paradigm, the ability to intentionally switch auditory selective attention is tested when applying different methods of spatial reproduction. Essential differences between real sources, an individual and a non-individual binaural synthesis reproduced with headphones as well as a binaural synthesis based on Cross-Talk Cancellation are found. This indicates how the loss of individual information reduces the ability to inhibit irrelevant information. Differences in performance measures occur also with regard to the target’s spatial position. Reliable findings on the spatial localization ability are confirmed applying the listening paradigm on the intentional switching of auditory selective attention. As a step towards multi-talker scenarios in realistic environments participants are tested in differently reverberating environments. Switch costs are highly affected by reverberation and the inhibition is also impaired by to be unattended information. Age-related effects are also found when applying the binaural-listening paradigm, indicating difficulties for elderly to suppress processing the distractor’s speech.
