Research

Research at Audio Communication Group is dedicated to the communication of music and speech in acoustical or electro-acoustical systems. This includes topics such as electroacoustic recording, reproduction and playback technologies, realization of 3D virtual audio by means of binaural technology or sound field synthesis, technologies for the composition and realization of electroacoustic music and sound art, and empirical approaches to study the everyday reception of musical content via media. Typically, these are interdisciplinary studies reaching from humanities, cultural studies, across social sciences and psychology to computer science and engineering. 

Research Projects

ABC_DJ

How can brand attributes such as ‘sportiness’, ‘elegance’ or ‘reliability’ be represented by musical content and its acoustic features? To what extent does the cultural background of a listener influence the perception of these attributes?

Survey Music and Media

What are the dominating patterns of audio media usage in Germany and in which sense do they relate to societal and technological change?

Medium and Emotion

The technical reproduction of music alters the "language of emotions" in many respects – as a physical event and as a psychological phenomenon. Does it change its emotional effect as well?

3DMIN

The emergence of electronic sound synthesis not only gave birth to a vast repertoire of new musical sounds and techniques, yet it allowed performers to disconnect the aspects of sound production from its control.

The Acoustics of Historical Performance Venues for Music and Theatre

The project investigates today’s still preserved case studies of performative spaces in the Early Modern period and addresses the questions of their compatibility with the numerous innovative performative art forms, whose advent has been recognised as effective in Europe since the 1550s: i. e. early opera, chamber opera, concert (orchestra), singing voice, voice and other artificial sound.

Room Acoustics and the Performance of Music

The project investigates to what extent musicians adjust their way of playing to the room acoustical conditions of the performance space. The influence of room acoustical parameters on aspects of music performance such as tempo, loudness, dynamics and timbre is explored by means of virtual acoustical surroundings and computer based performance analysis.

The Concert Hall and its Mediatization

In how far does the experience of a live concert differ from listening to the recordings of (classical) music? This question is assessed here using an empirical qualitative and quantitative approach and while applying highly immersive and interactive audiovisual stimuli.

From Perception research to the aesthetics of experience: construction of “tonal” space by means of music and its technology

 A historical study that covers the discovery of spatial listening, its operationalization and the development of the first electroacoustic devices built for spatial compositions until aprox. 1985.

SEACEN

The design and the generation of virtual acoustic realities has become a central field of research, both as a basis for proprietary applications in media technology and virtual reality and as a research tool for other disciplines related to the generation, transmission, reproduction, and perception of sound.

Sound Field Synthesis for Line Source Arrays

Line Source Arrays are used for large-scale sound reinforcement (e.g. in arenas, stadiums, for open-air concerts) aiming at the synthesis of homogenous sound fields. The research objective is to find algorithms that are based on analytic sound field synthesis and that provide improved optimization strategies compared to purely numerical solutions. Subproblems may still be solved numerically if necessary.
