Ultrasonic metal welding is a solid-state bonding process in which metal workpieces are exposed to high-frequency vibrations. It is an effective joining technology with a wide range of industrial applications […]

Ultrasonic Metal Welding (USMW) is a quite important welding technique, because of the relative low heat this welding process generate, it is used in numerous industrial applications. However, this welding […]

The IHTA park is used as a case study for a lot of the institute´s research on auralisation and visualisation of urban scenes. An audio-visual model of the park already […]

Die Hörbarmachung urbaner Lärmszenarien mittels Außenlärm-Auralisationen ist neben geeigneten Modellen zur Simulation von Schallausbreitung- und empfängern angewiesen auf Modelle von bewegten Quellen wie beispielsweise PKW. In dieser Arbeit wird die […]

Auditory selective attention (ASA) is a common phenomenon which describes the ability to intentionally focus on a specific source of sound while ignoring other irrelevant sounds. Since in real life […]

In tropical countries, air conditioning systems are widely used to improve indoor climate. In many cases, natural ventilation can also provide thermal comfort for users with less energy consumption and […]

The simulation of audio-visual performance is despite technological advancements still a challenging task which usually requires researchers to simplify problems in order to reduce computational complexity, sacrificing both auditory and […]

Angetrieben durch die Reduzierung von Lärmbelastung und Simulation von Schallausbreitung kann akustische virtuelle Realität (AVR) zur Durchführung von Untersuchungen eingesetzt werden. Zunächst wird bildbasierte photogrammetrische Software verwendet, mit der ein […]

The term irrelevant sound effect (ISE) refers to a significant reduction in the immediate serial recall of lists of presented items, usually digits or letters, when irrelevant auditory sound is […]

Für die möglichst präzise Auralisation von virtuellen Umgebungen ist die Kenntnis des genauen Schallfeldes der akustischen Szene notwendig. Einen Anteil zum diffusen Schall liefert dabei die Streuung an unebenen Oberflächen. […]

A previous study showed that background noises and background speech deteriorate children’s listening comprehension, as children lack the ability to neglect irrelevant sounds. A classroomlike atmosphere is required for an […]

Head-related transfer functions (HRTFs) describe the filter process of the incident sound caused by reflection, refraction, diffraction and interference with the ear for a random source position in space to […]

Auditory selective attention (ASA) refers to the mental ability to resist distractors and to focus on a specific sound in a complex acoustic environment. Revealing the factors that affect people’s […]

This study investigates the impact of air diffuser noise on human well-being, which is relevant due to its widespread use in residential and commercial buildings. The objective is to determine […]

The acoustic propagation of sound in the open field or in the interior can be calculated efficiently and in high quality by geometric simulation methods. However, for correct simulations, accurate […]

Nowadays, more and more conversations are conducted via technical aids, such as computers or mobile phones. In technology, there can be connection or processing problems that lead to disturbances in […]

In modern life, the proportion of computer-mediated conversations is gradually increasing, e.g., lectures via zoom, or virtual reality (VR). In real-life, information is perceived multi-modal: in addition to visual information, […]

Audio-visual experiences of modeled spaces play a key role when studying the human perception of the built environment, and the results should give us an intuitive sense of the real […]

Every day we are exposed to background noise with a multitude of simultaneous noises from different origin, for example on the bus, at work, or at a party. Nevertheless, we […]

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 […]
