Ultrasonic Metal Welding (USMW) is a technique used for numerous industrial applications. However, the welding process is in fact poorly known, leading to unexplained variations of strength. This presentation will […]
Theoretischen Modellen für das Schallfeld über porösen Absorbern liegt in der Regel die Annahme einer mindestens in einer Dimension unendlich ausgedehnten Materialschicht zugrunde. In der praktischen Anwendung, zum Beispiel bei […]
The measurement of the absorption coefficient in reverberation chambers according to the international standard ISO-354 shows a poor reproducibility between laboratories. One reason is the non-uniform distribution of absorption due […]
Sophia Psarra The Bartlett School of Architecture University College London Venice with its many islands in the lagoon is a city that has throughout history hosted many diverse innovations. From […]
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, […]
Thanks to modern auralization methods, simulated aircraft flyovers can be experienced in virtual environments. Listening to such an auralization provides a more sophisticated impression of annoyance of aircraft noise in […]
As a basis for potential sound perception studies in outdoor environments, the PAAD group is developing a 3D model of the adjacent outdoor area to the institute. The original request […]
Noise can cause stress, which leads to measurable physical reactions as well as it can impair intentional switching of auditory selective attention (ASA). In children, this can reduce the learning […]
Jian Kang Bartlett School of Environment, Energy and Resources University College London This talk explores putting soundscape into the intentional design process, by proposing a soundscape design framework for urban […]
Soundscape studies are showing the importance and the benefits regarding the sonic the environment in our daily lives. The soundscape paradigm shift highlights not just negative aspects, common on environmental […]
Ultrasonic Metal Welding (USMW) is solid-state bonding process where two metal pieces are joined by the application of ultrasonic vibrations. This thesis focuses on the study of the sonotrode during […]
The absorption coefficient is a central parameter in the room acoustic design process. It can be measured in an impedance tube for normal sound incidence or in the reverberation chamber […]
Huawei is founded in 1987 in Shenzhen, China. Huawei is a leading global provider of information and communications technology (ICT) infrastructure and smart devices. Starting from the 1st of Sep […]
Aachen based, KLANG:technologies produces Hard- and Software to deliver immersive, three dimensional in-ear monitor mixes for musicians. This is achieved using binaural technologies. The focus is to give the musician […]
Over the past few decades, research began to focus increasingly on the use of spherical microphone arrays to study the spatial properties of acoustic wave fields. To estimate the plane […]
In virtual audio, sound sources need to be modeled as realistically as possible to achieve a sense of immersion in the scene. The human auditory system performs an analysis of […]
Bone conduction has a big impact on the perception of the human being. Even though headphones are used by a billion of people around the world, it was yet not […]
From October 2019 to March 2020, I worked as an intern at Device Vodafone GTM Department in Düsseldorf Huawei. Huawei Technologies Co., Ltd., whose headquarter is located in Shen Zhen […]
In this thesis, the mutual information and interaction between different objective distance metrics for HRTF comparison were analyzed and evaluated. For this purpose, tools such as correlation analysis, principal component […]
Ultrasonic metal welding (USMW) is a kind of solid-state bonding technique for connecting similar or dissimilar metals using extremely fast frequency oscillations (ultrasonic frequencies). However, some details of vibration during […]
