Modification of the size and shape of an auditorily perceived space is studied with multiple reverberation enhancement systems. A setup consisting of a microphone and an array of loudspeakers on each wall was installed in an acoustically dry room. Acoustic response was generated with a time-variant reverberation algorithm which prevents the acoustic feedback. A subjective test with ten subjects indicated that by applying different reverberation time in different directions the perceived shape and size of the space can be changed. The prototyped system has potential applications in live performances and in education.
