Research Topics

Fraunhofer IDMT has long-standing experience and extensive know-how in audio signal processing and sound field reproduction as well as psycho- and electroacoustics. We are proud to say that we are among the worldwide leaders in research and development regarding spatial sound reproduction. For our achievements in research and development regarding solutions based on Wave Field Synthesis (WFS) technology, our acousticians in 2003 received the Thuringian Award for Applied Research. In 2010, Fraunhofer IDMT won the Thuringian Innovation Award for the development of a flat-panel loudspeaker.

Fraunhofer IDMT is a member of a number of boards (both national, European, and world-wide) regarding standardization and technology development.
