Bass enhancement for automobile multimedia system using active noise equalizer

The performance of audio bass reproduction in the automobile cabin is constrained by the space in the cabin itself. However, there is a rising demand for better multimedia experience in the automobile. In this paper we propose a novel system using a multi-frequency active noise equalizer to tune the engine noise. The simulation results show that this system automatically enhances the bass of audio by tuning the engine noise into a useful component of the bass reproduction in the cabin.
