Claim Text:
1. A hearing aid apparatus for wearing use by a user comprising: a frontend sound collector configured to collect a frontend signal; a backend sound collector configured to collect a backend signal; and a sound processor configured to process the frontend signal and the backend signal; wherein the sound processor comprise: a frontend delayer configured to apply a frontend delay coefficient to the frontend signal to produce a delayed frontend signal; a backend delayer configured to apply a backend delay coefficient to the backend signal to produce a delayed backend signal; a multiplier configured to weight the delayed backend signal by a backend coefficient to produce a weighted backend signal; and an adaptive filter configured to process the delayed frontend signal and the weighted backend signal to produce an adaptive filter output signal; wherein the frontend sound collector comprises a left channel frontend collector configured to collect a left channel frontend signal and a right channel frontend collector configured to collect a right channel frontend signal; and the backend sound collector comprises a left channel backend collector configured to collect a left channel backend signal and a right channel backend collector configured to collect a right channel backend signal; the frontend delayer comprises a left channel frontend delayer configured to apply a left channel frontend delay coefficient to the left channel frontend signal to produce a delayed left channel frontend signal and a right channel frontend delayer configured to apply a right channel frontend delay coefficient to the right channel frontend signal to produce a delayed right channel frontend signal; the backend delayer comprises a left channel backend delayer configured to apply a left channel backend delay coefficient to the left channel backend signal to produce a delayed left channel backend signal and a right channel backend delayer configured to apply a right channel backend delay coefficient to the right channel backend signal to produce a delayed right channel backend signal; and the multiplier comprises a left channel multiplier configured to weight the delayed left channel backend signal by a left channel backend coefficient to produce a weighted left channel backend signal and a right channel multiplier configured to weight the delayed right channel backend signal by a right channel backend coefficient to produce a weighted right channel backend signal.
