Abstract
In room acoustics analytical formulas and computer simulations can be used to predict the acoustics of spaces, not only in terms of reverberation but other perceptual aspects, too, which are related to the perception of music or speech. In this context the room impulse response is the function of main interest. It can be measured by using sophisticated instrumentation and signal processing, or it can be simulated with computer models. In the process of auralization the data and signal processing enables one to listen into the simulated rooms in order to interpret the sound in the room aurally. In real-time implementation, this is a valuable extension of the technique of virtual reality.
