SPATIAL QUEUE AND FEEDBACK

摘要

PROBLEM TO BE SOLVED: To provide a hearing aid capable of obtaining advanced sound source localization.SOLUTION: A hearing aid 10 includes: a BTE type hearing aid housing; BTE type microphones 14 and 16; an ITE type microphone 26; adaptive queue filters 42 and 44; a processor 18; an output converter 22; an adaptive feedback canceller including a subtractor 62; and an adaptive control device 56. When an output for modeling a feedback path between the output converter 22 and the BTE type microphones 14 and 16 is provided to the subtractor 62, the adaptive feedback canceller outputs a difference to the adaptive queue filters 42 and 44. The adaptive control device 56 controls the adaptive queue filters 42 and 44 such that a difference between the output of the ITE type microphone 26 and a coupled output to be obtained by using the adaptive queue filters 42 and 44 is reduced.
