Institute of Communication Acoustics

Auditory communication and processing of acoustic signals occupies a dominant position in information science and technology; mobile communications, broadcasting services, hearing aids, and sound reinforcement systems being well known examples of its application areas. Furthermore, acoustic signal processing for man-machine communication is of great importance, e.g. in automatic speech recognition, dictation, and speech dialog systems, and for access control. Current research aims at making several modes of human-machine interaction (auditive, visual, tactile) concurrently available and integrated into novel applications.

The information technology aspects of communication acoustics rest on four pillars:

  • physical acoustics,
  • human perception (e.g. psychoacoustics),
  • digital signal processing and
  • machine learning

whereby the interactions between these areas are especially appealing. The Institute of Communication Acoustics embodies these topics in research and education. Our activities are channeled into the following research groups:

  • Speech and Audio Signal Processing
  • Cognitive Signal Processing
  • Adaptive Systems for Signal Processing
  • Engineering Models of Auditory Perception

The Institute is equipped with a high speed computer network, workstations and real-time signal processing systems. Furthermore, we possess equipment and rooms for acoustic measurement.
