SUMMARY:Merino-Martinez: Acoustic imaging in aeroacoustic applications
DESCRIPTION:Aircraft and wind turbine noise emissions are increasingly important issues for society due to the noise annoyance and negative health effects in local communities\, as well as for the industry due to operational limitations imposed by noise regulations. The field of aeroacoustics aims at understanding the noise generation mechanisms behind these emissions and\, ultimately\, device noise reduction strategies to mitigate them. Microphone arrays and acoustic imaging methods have become the standard approach in experimental aeroacoustic research. In a nutshell\, by using multiple synchronized microphones and analysing their respective signals and their time delays\, we can apply acoustic imaging methods to visualize sound and identify and study all the noise sources present in complex systems\, such as aircraft\, wind turbines\, drones\, etc. This talk will discuss the basics of signal processing required for understanding acoustic imaging algorithms. The main limitations of this approach\, such as limited spatial resolution or the presence of sidelobes (spurious sound sources) will be explained\, as well as advanced techniques to mitigate them. A wide variety of experimental applications\, including wind-tunnel measurements and field experiments with full-scale aircraft and wind turbines will be presented. \nMelden Sie sich hier an um Einladungen zu den Kolloquium-Vorträgen per E-Mail zu erhalten.\nRegister here to receive the invitations to colloquium talks via e-mail. \nZoom-Meeting-ID: 954 4073 3814\nPasswort: 450783

SUMMARY:Lautenbach: The acoustical design process of a classical concert hall
DESCRIPTION:In this talk we will follow the acoustical investigations in the design process of a classical concert hall\, from the first talk with the client\, listening to several halls\, setting the goals\, acoustic modelling: computational and with a scale model\, the interaction with the architect\, construction and HVAC engineers\, to the measurements and first rehearsals of the finished hall. Of course\, we will also compare the outcome of the hall to the goals and the models. The new Casals Forum of the Kronberg Academy is in this talk the underlying hall that will be used as an example. This hall is very interesting due to its non-conventional shape\, there is no other hall like it. \nThis talk is part of the PAADtalks! series. \nMelden Sie sich hier an um Einladungen zu den Kolloquium-Vorträgen per E-Mail zu erhalten.\nRegister here to receive the invitations to colloquium talks via e-mail. \nZoom-Meeting-ID: 954 4073 3814\nPasswort: 450783

SUMMARY:Li: Short-term memory performance under audio-visual mismatch of lip-movements
DESCRIPTION: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\, sound as auditory information is received and remembered along with coherent visual cues\, such as lip-movement. However\, due to the instability of the network in video-calls or due to the quality of the VR scene design\, there can be a mismatch between auditory and visual content\, i.e.\, the lip movement and the heard voice. It is possible that this audio-visual mismatch impedes memory performance.\nThe aim of this thesis is to evaluate the effect of audio-visual mismatch regarding the lip movement and the spoken word on short-term memory by means of a serial recall listening experiment and to analyze the results with regard to known short-term memory mechanisms. Furthermore\, it is investigated whether the real lip movements and the lip movements of the virtual people affect the results in a different way. The results can help for future development of VR scenes.\nThe lecture will be given in German. \nMelden Sie sich hier an um Einladungen zu den Kolloquium-Vorträgen per E-Mail zu erhalten.\nRegister here to receive the invitations to colloquium talks via e-mail. \nZoom-Meeting-ID: 954 4073 3814\nPasswort: 450783

SUMMARY:Infantes: Development of a methodology for architectural reconstructions using point clouds including data capture and management
DESCRIPTION:Point Clouds has been used in architectural representation and digital reconstruction\, usually are called Digital Twins. These models should offer measurement accuracy and complete compatibility in all phases of architectural design and simulation. The standards of data treatment and the pipework available are licensed by software companies unable to offer the control of the information neither to be flexible in all cases\, especially in historical buildings and singular analysis projects. Digital Twins are used in multiple architectural studies\, some examples are structural analysis\, historical documentation\, heritage studies\, thermal analysis\, topography\, urban management and landscape. The usage of different software from different companies generates one-way pipeline file formats that lakes compatibility in multidisciplinary studies. In order to achieve full compatibility between multiple studies\, available data has to be converted or modified in several different ways depending on the software used. \nTo achieve our goals\, the methodology developed must be flexible in all its phases and be able to be tuned to generate the best possible model. Traditional data management pipelines require adapted data capture to the type of file needed and the program used. Our work has been focused to adapt all data capture techniques using open-source technology to achieve a unified and flexible methodology by using own automatized modular scripts. We also achieve full data control by modifying data structures\, calibrating optics or re-writing file formats with data replacement. To fulfill all needs and optimize data capture we ensure cross-compatibility between all forms of raw data without information loss either when using software from companies as Autodesk\, Adobe\, Bentley\, PolyWorks\, etc. \nSome of the type of procedures included in our methodology are: Fully controlled scan alignment\, point cloud management and processing\, Photogrammetry (also from video)\, TLS\, Drone mapping\, Reality-to-BIM\, 3D meshes with controlled accuracy textures and topographical/GIS compatibility. All of the procedures are currently being used in real cases scenarios. \nThe presentation will be focused in explaining this methodology step by step through a series of real projects where our methods have been applied and cross-compatibility is achieved. \n  \nMelden Sie sich hier an um Einladungen zu den Kolloquium-Vorträgen per E-Mail zu erhalten.\nRegister here to receive the invitations to colloquium talks via e-mail. \nZoom-Meeting-ID: 698 1044 5314\nPasswort: 622534
