Abstract

A dual-channel maximum-length-sequence test system has been implemented to characterize the electroacoustic performance of hearing aids. The system applies a frequency-shaped maximum-length sequence to a hearing aid as an acoustic stimulus and measures the acoustic response of the aid in an IEC standard occluded-ear simulator. Measurements are completed in one-third the time required for noise-based measurements, and the responses measured by the system compare favorably to those measured via conventional noise-based methods.
