Room transfer functions and osund field control

摘要

Active contorl requreis etimating transfer funcitons (TFs) and hteir inverse TFs in the acoustic systmes to be controlled.Acoustic systems like rooms have ocmplicated TFs,which are characteized by myriad poles and zeros.THis article describes statistical properties of distrivbutions of the poles and zeros in TFs,and mentions the inverse filtering of TFs in a sound field.
