The aim of auralization in room acoustics is to make the acoustics of a room audible. That is to say the result of an auralization is an aural impression of a source playing inside an existing or non-existing room. Kleiner et al. defined the term auralization as follows [Kleiner, 1993]: “Auralization is the process of rendering audible, by physical or mathematical modeling, the sound field of a source in a space, in such a way as to simulate the binaural listening experience at a given position in the modeled space.” The motivation is obvious: instead of describing the acoustic properties of a room by abstract numerical quantities it is possible to directly listen to the sound, which makes the results of room acoustics design more concrete. Another advantage is that people who are no experts in room acoustics can get an impression of different steps of a concert hall. A more general definition of auralization is given by [Vorl¨ nder, 2008]: “Auralization is the a technique of creating audible sound files from numerical (simulated, measured, or synthesized) data.”

As in 2011 the Acoustics and Audio Group moved from the Institute of Broadband Communications (IBK) to the Signal Processing and Speech Communications Laboratory (SPSC), the puplishing location of this thesis also was transfered from the IBK to the SPSC-website.
