This presentation discusses the advantages and limitations of using Dynamic Time Warping (DTW) to quantify the similarity between measurements of different weldings. In this project, machine vibrations and airborne sound occurring during Ultrasonic sheet Metal Welding are […]
Large-scale microphone arrays allow for a detailed analysis of room acoustics and the identification of individual sound waves as they move about the room. Although these data help us to […]
This project is a cross-site investigation with the university of Oldenburg. 14 participants were measured at both sites in terms of HRTFs and HpTFs at two different positions: at the […]
According to ISO 345, the random-incidence sound absorption coefficient is measured in a reverberation room by determining the different reverberation times with and without the absorber inserted. The sound field […]
Poor acoustic conditions in educational institutions affect children. A noisy environment puts children under constant stress and impairs their performance. Most of the present research and standards concerning classroom acoustics […]
This talk will address the musical blind source separation problem: given multiple instrument tracks recorded together, how can each be isolated from the others given no additional knowledge about the […]
Already in ancient times, the goal existed to design appropriate environments to transport acoustic signals from a sound source to an audience. Strongly connected to this is the interest to […]
Auralizations of simulationed aircraft flyovers can be used to experience aircraft noise in virtual environments. Compared to averaged sound pressure levels or noise maps, listening to such an auralization provides […]
Das binaurale Hören und damit insbesondere die Fähigkeit, Schallquellen im Raum lokalisieren zu können, spielt eine bedeutende Rolle im alltäglichen Leben eines jeden Menschen. Genutzt wird dafür jeweils die eigene, […]
The goal of this thesis is building an extension that can reduce the interference of the noise in some precision measurement experiments, which means increasing the directivity of the microphone. […]
Im Rahmen dieser Bachelorarbeit werden Außenohrübertragungsfunktionen (head-related transfer functions, kurz HRTFs) basierend auf 3D-Modellen untersucht. Eine HRTF beschreibt den richtungsabhängigen Filterprozess, den ein Schallereignis ausgehend von einer Schallquelle bis zum […]
In January 2021, a junior research group will be born inside RWTH Aachen University. The Person-focused Analysis of Architectural Desgin group aims to elaborate an architectural design categorization based on […]
Ultrasonic metal welding (USMW) has received significant attention in recent years. It is particularly suitable for connecting electrotechnical components and has been widely used in various industrial applications. However, the […]
Binaural hearing is a complex process that is significantly influenced by physical attributes of the listener. These dependencies on the shape of the torso, head, but also the resonance properties […]
In order to provide a diagnosis about the urban sound environment, especially for traffic, sound classification using deep learning with convolutional neural networks has received increasing attention. There are already […]
Kommunikation im Alltag findet selten in einer ruhigen und nachhallarmen Umgebung statt. Tatsächlich spielt sich ein Großteil der Kommunikation und des Lernens in lauten, halligen und von Störgeräuschen geprägten Umgebungen […]
In Bildungseinrichtungen sind Kinder häufig inneren und äußeren Lärmeinflüssen ausgesetzt. Die externen Geräusche haben Lärm durch anliegende Straßen oder Spielplätze oder gegebenenfalls durch Flugzeuge zur Ursache. Auf der anderen Seite […]
The façade sound insulation is important in perspective that the growing traffic noise is causing annoyance in daily life activities in residential dwellings as well in worksites. The available façade […]
In recent times, measurement systems for acquiring individual head-related transfer functions (HRTFs) by inserting microphones at the entrances of both ear canals and recording the emitted sound signals of loudspeaker […]
The impulse response of a room describes the acoustic transmission path between a given source and receiver. One way to acquired an impulse response is by using simulations of a […]
