Regardless of the field, measurements are essential for the validation of theories and for making well-founded decisions. A criterion for the validity and comparability of measured values is their uncertainty. […]
Drägerwerk, short Dräger, is a leading company in the fields of both medical and safety technology. Based in Lübeck, the company has employees and customers around the globe and is […]
Building acoustics auralization is used to assess the perceptual aspects of sound transmission in built environments to provide the guidelines for architectural constructions and to evaluate the noise effects on […]
First part describes the new building acoustics and psychoacoustics laboratories launched in 2020. Second part is the overview the important recent publications, which deal with, e.g., room acoustics in open-plan […]
Open-plan offices have been popular for their significant advantages such as economical savings and flexible layout design. However, according to several questionnaire studies, noise, and in particular, irrelevant speech has […]
Dieser Vortrag beschäftigt sich mit der Ersatzschaltbildmodellierung des Knochenschalls. Die Knochenleitung beschreibt die Übertragung von Schall als Schwingungen im Schädel Knochen und dem umgebenden Weichteilgewebe zum Innenohr. Es gibt fünf […]
People perceive most events with several senses at the same time. In everyday life, these different sensations coincide in time and space to form one coherent percept. However, in online […]
In recent years, the use of virtual reality in research has greatly increased due to its ability to recreate complicated and realistic circumstances in a well-controlled laboratory environment. In this […]
Over the last few years, virtual reality (VR) has emerged as a new technology that is allowing scientific research to investigate topics from another perspective. This is due to the […]
This paper describes the results of a subjective evaluation of classroom auralizations with different levels of detail(LOD) by a listening test. Computer Modeling of the classroom with different LOD and […]
Conventional acoustic simulations are based on CAD models. The creation of the 3D model requires modeling expertise and time. Additionally, the variety of model strategies makes this process difficult to […]
Lärm wird nicht nur oft als störend empfunden, sondern kann sich negativ auf unsere physische und psychische Gesundheit auswirken. Während Umgebungsgeräusche vor 200 und mehr Jahren noch ausschließlich natürlichen Ursprungs […]
The internship was completed at Pixargus GmbH, a small company in Würselen, Germany. The presentation will provide an insight into the work areas of the internship and the company itself. […]
The frequent issue of noise-induced hearing loss (NIHL), especially in the army, has encouraged the research and development of hearing protection devices (HPDs). HPD research and development in the area […]
Auralization is a technique which allows the rendering of realistic 3D audio based on virtual spatial scenes. Certain sound propagation parameters (or so-called auralization parameters) such as propagation delay, atmospheric […]
For Concert Halls, most people agree that the acoustic quality is a quintessential element of the success of the project, and often the acoustics is considered as being more important […]
Auralisation describes the process of generating and presenting audible sound using computer programs and audio hardware. Since the result is perceived naturally by the human's auditory system, a demonstration by […]
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 […]
From the beginning of their auditory development, children are immediately confronted with the challenge of orienting themselves in complex acoustic situations. Whether a parent’s voice or a passing vehicle, it […]
