Modal equalization of low-frequency room modes has recently been proposed as a method to improve sound reproduction in spaces where modal decay time is too long. Modal equalization is achieved by signal processing reducing the pole radii of problematic modes in the overall transfer function. In this paper, we compare the performance of two proposed methods for designing modal equalizers. Comparison includes a preliminary subjective listening test indicating a possible marginal improvement by modal equalization over conventional magnitude equalization.
