Abstract—In this paper, a new algorithm of Smart Acoustic Room (SAR) system is prensented for partitioning room acoustically. That is, in different places of the room, one can hear to the desired signal. This is realized by robust estimation algorithm for well control of room acoustic impulse responses. Therefore, unwanted music or speech signal is canceled, while, at the same place, the desired signal (the desired music or speech) could be heard. And also, the application of smart acoustic room system for car hand-free telephone is preseted. By using this new structure, echo and backgroud music in the car will be canceled. In other words, people at far-end will not hear the background sound and echo signal from the near-end room. The computer simulation and experiment results support the theoretical findings and verify the robustness of the proposed algorithms.

Index Terms—Acoustic impulse response, Smart Acoustic Room (SAR) system, Hand-free telephone.
