Abstract
The invention relates to simulation of sound fields in enclosures, for instance for application in listening tests, where test subjects assess the sound quality or other sound perception characteristics of the sound field. According to a specific embodiment, the system comprises a binaural synthesis portion which synthesizes sound for instance from a sound-reproduction equipment based on measured impulse responses of an actual room stored in a data base () and a binaural recording portion comprising a data basefor storing binaural recordings of other sound signals made in the room. Data from these databases are mixed () and reproduced by means of a headphone () provided with a head tracker () for tracking the movements of the listener's head. The invention furthermore comprises the use of cross-fading functions () to enable the dynamic listening conditions, where the movements of the listener's head are taken into account during the simulation process.
