Zusammenfassung:The research project “LIPS – Live Interactive PMSE Services” aims at enabling tele-conferencing and distributed music performances in a most natural and immersive way. To provide a most plausible acoustic environment for the distributed interacting participants the Institut für Kommunikationstechnik (IKT) is working on Immersively Connected Rooms, where two remote rooms interact as they were coupled through a virtual window building a virtually combined larger room.In this contribution the geometric acoustic simulation tool RAVEN was used to compute the sound field in the virtually combined room. By using the spatial audio reproduction techniques Higher-Order Ambisonics (HOA) and Vector-base Amplitude Panning (VBAP) auralizations of these sound fields were generated for a listening position in the room on this side of the virtual window, where the source was located on the other side. These auralizations were then played back through a 36.4 loudspeaker setup.To evaluate how well the auralized room acoustic corresponds to the simulated acoustic environment and how the reproduction room influences the auralization, a set of room acoustic parameters was obtained from simulated and measured room impulse responses, which were then compared to each other.
