Abstract: A hearing aid includes: at least one microphone for provision of at least one microphone audio signal in response to sound received at the at least one microphone; a signal separation unit configured to provide an estimate of a target signal and an estimate of a masker signal based on the at least one microphone audio signal; a frequency modifying unit configured to modify a frequency content of at least one of the estimate of the target signal and the estimate of the masker signal, to thereby output the estimated target signal and the estimated masker signal substantially in different frequency bands; and a receiver for conversion of a combination of the estimate of the target signal and the estimate of the masker signal output by the frequency modifying unit into an acoustic signal for transmission towards an eardrum of a user of the hearing aid.

Abstract: A hearing aid analysis system for objective determination of speech perception enhancement for a hearing aid under test uses prerecorded speech and a computer system that includes a speech recognition program. Hearing aid analysis circuitry is provided to receive a plurality of signals representing signals generated by speech sounds routed through different acoustic paths, and filter circuitry to simulate a hearing loss. The hearing aid is interfaced with the source of prerecorded speech sounds and the analysis circuitry. The computer system includes a control program that presents the prerecorded speech to the analysis circuitry to produce a degraded signal routed through the filter circuitry and a processed signal routed through the hearing aid and the filter circuitry. The speech recognition program then compares speech recognition from the degraded signal with speech recognition from the processed signal to determine an objective indication of speech perception enhancement forte hearing aid.

Abstract: A hearing aid analysis system for objective determination of speech perception enhancement for a hearing aid under test uses a source of prerecorded speech sounds and a computer system that includes a speech recognition program to evaluate the hearing aid under test. Hearing aid analysis circuitry is provided with processing circuitry to receive a plurality of signals representing signals generated by speech sounds routed through different acoustic paths, and filter circuitry to selectively simulate a hearing loss. The hearing aid under test is interfaced with the source of prerecorded speech sounds and the hearing aid analysis circuitry. The computer system includes a control program that operates to present the prerecorded speech sounds to the hearing aid analysis circuitry to produce a first degraded signal routed through the filter circuitry and a second processed signal routed through the hearing aid and the filter circuitry.
