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.
