摘要

•KF-HPNAH combined by PNAH and KF for reconstruction of sound source is developed.•The strategy of equivalent source configuration in WSM is solved successfully.•The 3D localization of source is improved by n (n = 40) hologram planes.•KF-HPNAH is accurate for sound source at frequencies between 200 Hz and 900 Hz.
