| Abstract: | In a different way from large space such as concert hall, we experience the sound coloring of the reproduced sound in the automotive space. It comes from the well-separated acoustic modes in the low frequency range up to the relatively high crossover frequency. The unwanted sound coloring can be reduced by equalization. But this is not a simple matter because the binaural responses are different in each single person and drivers are likely to move their head during driving. In this paper, we introduce a novel approach for the equalization of the low frequency response to compensate the coloring based on minimum phase inversion. We compare the proposed approach with the conventional least square based inversion and show the superiority of this approach with the experimental results. We also confirm that from the results of listening test. | ||
