Abstract(in English)	We can estimate a pitch by removing musical components using notch-type comb filters. But, when an input includes a percussion sound, the notch filters cannot remove all signal components. In this study, we propose a pitch estimation method for lower musical sounds including a percussion sound that has not realized. The pitch can be estimated by removing percussion sound from an input sound and musical components using notch-type comb filters. We tested the proposed method with piano sounds as lower musical sounds and 30 kinds of percussion sounds. As a result, we could estimate the pitch with the accuracy of 92.3%.
