| Abstract(in English) | Echo and, or howling suppression are quite important for acoustic public addressing (PA) systems.The authors investigate to stabilize PA systems by smoothing the transfer function(TF) including room acoustic properties.This article demonstrates that inverse filtering for the minimum-phase components of the TF is a powerful processing scheme for realizing stable PA systems.In particular,the experimental results and computer simulations promise that a smoothed inverse-filter is quite effective in spite of temporal variabilities in the TFs rather than the exact inverse filter. |
