People use speech to communicate, sharing information, knowledge, and stories, but the act of speaking and listening is no guarantee of a clear understanding. Schools are places where speaking and listening are primary methods of communication. In Brazil, it is a common practice to design a standard classroom and replicate it across the institution, be […]

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 show some recent work about studying the welding process based on measurements and the most recent model from the literature. From the literature model, a […]

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, in various fields of acoustics. For proper processing of simulation results, we usually rely on MATLAB and the ITA-Toolbox. Although COMSOL provides a MATLAB interface […]

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 real scenarios than reading averaged sound pressure levels or noise maps. For proper auralization results, translation and refraction due to wind and to inhomogeneity of […]

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 was to achieve an ecologically vaild representation of the outdoor environment, including different weather characterizations. In this presentation we will present the current state of […]

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 open public spaces, including four key components: characteristics of each sound source, acoustic effects of the space, social/demographic aspect of the users, and other aspects […]

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 for random incidence. To guarantee a standardized test environment for reverberation chambers, the international standard ISO 354 suggests a measurement procedure to increase the diffusivity […]

Yet, we know little about its pervasive and often hidden effects on our mental state and our brain. Despite growing interest in the neuroscience […]

In recent years, the use of techniques based on machine learning has increased and expanded to different areas. The increasing computing capacity and the availability of public datasets have allowed the development of these techniques, particularly deep learning, that today are considered the state of the art in topics such as pattern recognition, natural language […]

For more than 15 years the GPA has been working on the design and implementation of acoustic sensor arrays that by means of classical beamforming techniques allow to electronically position a beam in space. The evolution of acoustic array construction technologies will be analyzed from the analog field with conventional microphones, AD/DA converters and DSP […]

The building of a concert hall is a process of many aspects and stages - some of which have to do with acoustics. In this talk we will share insights from Müller-BBMs’ extensive experience in the topic by means of a project case study: Musikzentrum Bochum. The various acoustic planning stages within a given project […]

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 offices, office pods, perception of façade sound insulation, and wind turbine health effects. Third part gives an overview of current research projects, which deal with […]

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 than the architectural design. Yet it should be clear that architecture and acoustics are totally interwoven, and every architectural decision will have an acoustic effect […]

Implementing a Virtual Studio Technology (VST) host plugin with the auralization application Virtual Acoustics (VA) would allow VA to load and control the parameters of VST plugins as an input source to reproduce in a 3D scene. To approach this problem, I familiarized myself with Steinberg’s software, the VA platform, and subsequent software tools CMake, […]

Virtual Acoustics (VA) is a powerful framework for the auralization of virtual scenes and is developed at the Institute for Hearing Technology and Acoustics. It uses physics-based models for source, sound propagation and spatialization at the receiver and allows rendering scenes in real-time. Due to its modularity, VA can be applied to a variety of […]

Cathedrals are significant pieces of architecture, symbols of the European culture, whose grandiosity is the result not only of their extraordinary visual features, but also of their remarkable acoustic environment. This talk summarises the methodology utilised to analyse and preserve the acoustics of a sample of European cathedrals, which is based on the analysis of […]

Tateo Nakajima will give a talk that will present a selection of his projects and the evolution of his design practice, in light of the key influences that have shaped his work, current trends that he sees in the industry that impact his work. Tateo Nakajima was former Partner of Artec Consultants inc (NY), currently […]

Aalto Acoustics Lab (Espoo, Finland) is a collective of five professors working on different topics in audio and acoustics ranging from concert halls to acoustic materials and from virtual analog models to human superhearing. At the moment there are three post-docs and some 20 doctoral students working in the lab. This presentation will give an […]

I am a new doctoral candidate at the BMW Group & IHTA and I will give an overview of my past research. During my bachelor’s thesis at FAU in Erlangen, I worked on sound field synthesis in rooms with a loudspeaker array, employing a pressure matching approach in order to reproduce a desired sound field […]

A good part of the global burden of disease can be attributed to environmental factors, such as noise. With a high prevalence of mental health problems in lower socioeconomic groups it is important to understand how environmental exposures contribute to mental health. The focus of my research is on children as children are more vulnerable […]
