Michael Vorländer - Acoustic Virtual Reality for Perception Research

Date: 
Fri, 03/01/2013 - 1:15pm - 2:30pm
Location: 
Seminar Room
Event Type: 
Hearing Seminar
 

We've come a long way since the days when we thought that stereo speakers provided amazing sound playback.  We've out grown 5.1 and even more.

 

Just what does it take to accurately reproduce a sound field?  Which effects are important?  Why? When do the issues matter?

 

Michael Vorländer is an acoustics professor from Aachen Germany and is finishing up his visit at CCRMA.  We'll have a real-live discussion, with hyper-realistic 3-d audio, all in real time.

 

Who: Michael Vorländer (Aachen)

What:  Acoustic Virtual Reality for Perception Research

When: Friday March 1 at 1:15PM

Where: Seminar Room at CCRMA (The Knoll)

Why:  I want to know which parts of 3d sound matter

 

Bring your favorite 3d sound perceiver to CCRMA and we'll talk about what it takes to make it happy!

 

See you at CCRMA this coming Friday!

Acoustic Virtual Reality for Perception Research

The settings in sound fields used in hearing research, and in testing and fitting of hearing aids are usually simplified or reduced to fundamental physical fields, such as the free or the diffuse sound field. The concepts of such ideal conditions are easily introduced in theoretical and experimental investigations by using the direct-to-reverberant sound, for example. When it comes to real-world application of listening to music or speech, however, the field conditions are more complex with regard to specific stationary and transient properties in room transfer functions and the corresponding impulse responses and binaural parameters. In this presentation it is discussed how computer models can be used for the creation of complex virtual acoustic scenes in rooms. After an overview, the VR system developed at RWTH Aachen University and the acoustic CAVE technology are described in more detail, and demonstrated in videos and a real-time room auralization.

 

 

Biography

Michael Vorländer is Professor at RWTH Aachen University, Germany. After university education in physics and doctor degree (Aachen 1989 with a thesis in room acoustical computer simulation) he worked in various fields of acoustics. First research activities were focused on psychoacoustics, electroacoustics and of room and building acoustics. In 1995 he finished the qualification as university lecturer (habilitation, Dresden Technical University) with a thesis on reciprocity calibration of microphones. Since 1996 he is Professor and Director of the Institute of Technical Acoustics, ITA, at RWTH Aachen University. Michael Vorländer serves in several organizations. He was President of the European Acoustics Association, EAA, in the term 2004 – 2007 and now serves as President of the International Commission for Acoustics, ICA, for the term 2011-2013. He was awarded the Stephens Medal of the Institute of Acoustics, IoA, of United Kingdom in 2005, Fellow of the Acoustical Society of America in 2006, the Caracola of the Acoustical Society of Spain in 2009, and a Honorary membership of the Polish Acoustical Society in 2012. The research focus of ITA is auralization and acoustic virtual reality in its various applications in psychoacoustics, room and building acoustics, automotive and noise control.
