N2 - The aim of the modern communication technologies is an immersive experience. One of the applications that should provide the feeling of being together and sharing the same environment during the communication process is BEAMING. The goal of this paper is to improve audible spatial impression utilizing correct acoustical properties of the specific environments. Binaural room impulse response (BRIR) synthesis represents one of the main tasks in the binaural auralization. When the BRIRs are simulated, high order reflections (reverberation tail) are usually modeled statistically because of the high density of reflections. That can lead to metallic and unnatural sound. Also, room-specific sound envelopment feeling is lost. This paper investigates the possibility of using measured reverberation tail instead of the modeled one in BRIRs synthesis. Three cases are observed. In the first one, BRIRs measurement in a real room is performed. In the second one, synthesized BRIRs are used. BRIRs synthesis is realized using the image-source method for the early reflections and the artificial reverberation algorithm for the reverberation tail. The third case combines modeled early reflections from the second case and measured late reverberation from the first one. All three cases are evaluated and compared objectively based on the obtained room acoustic parameters as well as subjectively by listening tests.
