Mika: Filter creation for partially absorbing surfaces in the Image Edge Model

IHTA Seminarraum (60 Persons) and Zoom-Meeting (Hybrid) Kopernikusstr. 5, Aachen, Deutschland

The generation and propagation of noise is an ongoing research topic that affects everyone. Urban environments in particular suffer from high levels of noise pollution, which can negatively impact the […]

Fang: Validation of free-field sound scattering simulations

IHTA Seminarraum (60 Persons) and Zoom-Meeting (Hybrid) Kopernikusstr. 5, Aachen, Deutschland

The scattering coefficient is a crucial parameter in acoustics, as it plays a significant role in characterizing the scattering of sound waves from surfaces and materials. In this study, we […]

Vos: Overview of drone noise related topics

IHTA Seminarraum (60 Persons) and Zoom-Meeting (Hybrid) Kopernikusstr. 5, Aachen, Deutschland

There is a shift going on from manned aviation to unmanned aviation where drones, mainly DJIs are being used for social public purposes. The drones are easily distinguishable from other […]

Schröder: Parameterstudie zur Laufzeit von Virtual Acoustics

IHTA Seminarraum (60 Persons) and Zoom-Meeting (Hybrid) Kopernikusstr. 5, Aachen, Deutschland

Die Berechnungszeit eines Audioblocks ist für Echtzeit-Auralisationen von entschei- dender Bedeutung, da sie die realisierbare Latenz nach unten begrenzt. Diese Arbeit untersucht die Auswirkung verschiedener Konfigurationsparameter auf die Laufzeit der […]

Zhang: Analysis of standard scattering coefficient measurements

IHTA Seminarraum (60 Persons) and Zoom-Meeting (Hybrid) Kopernikusstr. 5, Aachen, Deutschland

The acoustic scattering of surfaces is very important in all aspects of room acoustics like in concert halls and reverberation rooms. The sound propagation can be calculated effectively and in […]

Bender: A study on voice quality and vocal fatigue of lecturers in lecture halls

IHTA Seminarraum (60 Persons) and Zoom-Meeting (Hybrid) Kopernikusstr. 5, Aachen, Deutschland

Voice disorders are more prevalent in occupational voice users, such as lecturers in universities. This thesis examines if a relationship between room acoustic properties of lecture halls and voice quality […]

Käppel: Untersuchungen zu Wiedergabeverfahren für irreguläre Lautsprecherarrays im Nahfeld

IHTA Seminarraum (60 Persons) and Zoom-Meeting (Hybrid) Kopernikusstr. 5, Aachen, Deutschland

Ambisonics ist ein weitverbreitetes Audiowiedergabeformat zur lautsprecherbasierten Reproduktion räumlicher Schallfelder. Klassische Ambisonics-Decoder basieren auf der Annahme ebener Wellen. Damit eine Fernfeldnäherung ebener Wellen für die Lautsprecher zulässig ist, müssen diese […]

Selvi: Industrial Internship at HEAD Acoustics GmbH

IHTA Seminarraum (60 Persons) and Zoom-Meeting (Hybrid) Kopernikusstr. 5, Aachen, Deutschland

This presentation is about the industrial internship completed at HEAD acoustics GmbH in the department Sound Perception & Assessment. Two major tasks are presented. First of these is about the […]

Kamps: Synthesis of aircraft sound emission for auralization

IHTA Seminarraum (60 Persons) and Zoom-Meeting (Hybrid) Kopernikusstr. 5, Aachen, Deutschland

Aircraft sound emissions are often associated with health risks for humans. Consequently, reducing the noise levels has been a research goal for many years. However, a simple level reduction does […]

Zhu: Emulation of RRAM crossbar array on FPGA Platform

IHTA Seminarraum (60 Persons) and Zoom-Meeting (Hybrid) Kopernikusstr. 5, Aachen, Deutschland

RRAMs (Resistive Random Access Memory) have resistive switching characteristics and show potential for fast speeds, high energy efficiency, and three-dimensional stacking. We aim to overcome the limitations of traditional von […]

Liu: Enhancing Tonality Prediction Using Neural Network

IHTA Seminarraum (60 Persons) and Zoom-Meeting (Hybrid) Kopernikusstr. 5, Aachen, Deutschland

This presentation is about my industrial internship tasks at HEAD acoustics GmbH in the Sound Vibration Perception (SVP) department, with a focus on the development and utilization of a neural […]

Katz: Experimental virtual archaeological-acoustics – Bringing auditory experience into social science and architectural research and design

IHTA Seminarraum (60 Persons) and Zoom-Meeting (Hybrid) Kopernikusstr. 5, Aachen, Deutschland

Research in historical musical acoustics has traditionally emphasized instrument fabrication, material choices, and construction impact. Similarly, musicological, theatrical, and religious studies have delved into various aspects of historical contexts. However, […]
