Abstract :
In this paper, the effect of numbers of bands for acoustic feedback cancellation (AFC) in multi-band compression hearing aids is investigated. Significant improvement in the performance of the AFC system is demonstrated via computer simulations based on different hearing loss characteristics. Moreover, the increment of the dynamic range of hearing when employing multi-band compression hearing aids is shown, as compared to that of conventional hearing aids
