Abstract EN
We propose an alternative approach to the Balanced Model Truncation method (standard method).
This approach reduces substantially the order of minimum-phase inverse filters for equalizing room acoustics.
This method is based on a property of the filter z transform function, which modifies the corresponding FIR coefficients before the application of the standard technique to the modified FIR coefficients filter version.
In the standard technique, the Hankel singular values plot is the chief guide for a user for the selection of a reduced filter order.
Results for minimum-phase inverse filter corresponding to partial equalization of measured acoustic impulse response show the superiority of the proposed method over the standard technique, in terms of reduced filters order selection.
