This internship centered on the board design and software development of electronic systems for testing robotics developed at Redwire Space Europe. Hardware developed for space applications has strict requirements due to its high cost and the inability to perform repairs in space. Incomplete or faulty on-ground testing has been shown to significantly increase project risks, […]

Die individuelle head-related transfer function (HRTF) ist essenziell für die räumliche Audiowiedergabe. Die individuelle Messung der HRTF ist aufwendig, deshalb liegt eine breite Auswahl an Schätzverfahren vor. Diese können ohne Hörversuch jedoch nicht eindeutig hinsichtlich ihrer Qualität bewertet werden. Zur Einordnung von acht HRTF-Schätzverfahren hinsichtlich der Lokalisierungsgenauigkeit wurde deshalb in Vorarbeit ein Hörexperiment durchgeführt. Im […]

Kollmorgen entwickelt und produziert die Steuerungselektronik für Aufzugsanlagen. In einem 20min Vortrag werden folgende Themen vorgestellt: - Motivation für ein Praktikum bei Kollmorgen - Die Aufzug-Branche und die Rolle von Steuerungsherstellern darin - Ablauf des Praktikums - Die Arbeit als […]

In my internship, I investigated the intelligibility of speech in noise for hearing aid wearers. As communication takes place on a daily basis, good understanding of conversation partners, especially in a noisy environment, is crucial for everyday social life. During the internship with the R&D Sound and Audiology department at WS Audiology in Erlangen, I […]

In diesem Vortrag wird ein 6-monatiges Industriepraktikum in der Engineering Services Abteilung der HEAD acoustics GmbH vorgestellt. Während des Praktikums wurde eine Vielzahl an Projekten in den Themengebieten Active Sound Design (ASD), Psychoakustik und allgemeine akustische Messungen im Auftrag von Kunden oder für die firmeneigene Entwicklung bearbeitet, von denen die relevantesten präsentiert werden. Hierzu zählen […]

Im Rahmen des 18-wöchiges Industriepraktikum bei der Delphin Technology AG, einem mittelständischen Unternehmen im Bereich der industriellen Mess- und Prüftechnik, konnten praxisnahe Erfahrungen in verschiedenen Bereichen in der Entwicklung von modenen Messsystem gesammelt werden. Ziel des Praktikums war die praxisnahe Anwendung und Vertiefung theoretischer Kenntnisse aus dem Studium sowie die Gewinnung umfassender Einblicke in die […]

During my internship at HEAD acoustics, I mainly worked on signal processing for physiological measurements. In hearing tests and driving simulations in virtual reality, various physiological parameters are recorded over time in order to quantify the influence of acoustic stimuli on the test subject instead of relying solely on the subsequent questioning of the test […]

This presentation summarizes the work I carried out during my 18-week internship at the Hearing Aid Business Unit of Shanghai United Imaging Microelectronics Technology Co., Ltd. My tasks included various standardized measurements such as electroacoustic testing according to GB/T and IEC standards, as well as directivity, reliability, and battery voltage testing. The main focus of […]

The internship at KARL STORZ SE & Co. KG contributed to the optimization of a hardware system used in electrosurgical applications. The project focused on improving power transmission efficiency and system reliability through experimental measurements and circuit simulations. Various diagnostic methods, including impedance analysis, infrared thermography, and high-frequency signal evaluation, were applied to identify and […]

This presentation details an internship conducted at the Kärcher Sound Lab focused on minimizing structure-borne noise. The central project involved the design, construction, and validation of a custom test rig for the dynamic characterization of viscoelastic damping elements. The resulting method allowed for measurement of frequency-dependent material properties and decoupling performance. The test rig was […]

This presentation will report on an acoustical engineering internship that was completed with and supervised by the American acoustical consulting and engineering company Brooks Acoustics Corporation (BAC) in Pompano Beach, Florida. Since 1992, the BAC team has contributed to over 1,100 national and international projects and actively participates in the academic, standards and professional communities […]

There are several standardized methods for characterizing the reflection properties of materials, such as the classic reverberation chamber method and the impedance tube method. For practical application, some alternative in-situ methods have been developed in recent years. However, all these methods to determine the reflection factor can lack robustness and reliability. In this report, a […]

During the internship at GoerTek Inc., the focus was primarily on the analysis and optimization of acoustic systems for “True Wireless Stereo Earbuds”, so-called TWS devices. The main responsibilities included conducting both subjective and objective tests based on acoustic performance, evaluating products through metrics such as frequency response curves, distortion curves, and manual listening tests. […]

Active Noise Cancellation (ANC) and Talk-Through (TT) modes are common features in modern headsets. ANC typically provides enough attenuation that background noise becomes difficult to characterise. In this internship, several warning signals, such as passing cars and shouted speech, were recorded and used as background noise, and multiple headsets with ANC and TT were evaluated […]
