Abstract :
In this paper, the smart acoustic room (SAR) system is presented 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, we apply the SAR system into the double-talk echo canceling. The computer simulation results support the theoretical findings and verify the robustness of the proposed algorithms.
