HEARING AID NOISE REDUCTION METHOD, SYSTEM, AND APPARATUS

摘要

A computer-implemented method including receiving a first signal from an input device of a hearing aid. The first signal may include a noise signal. The computer-implemented method may include low-pass filtering first periodic samples of the first signal, and the first periodic samples may be approximately periodic with respect to a period of the noise signal. The computer-implemented method may further include low-pass filtering second periodic samples of the first signal, and the second periodic samples may be approximately periodic with respect to the period of the noise signal. The second periodic samples may also be phase shifted relative to the first periodic samples. Hearing aid systems and apparatuses are also disclosed.
