Special-Purpose Virtual Audiometer

摘要

A Virtual Audiometer is described. The audiometer is designed so that the userscan measure their own thresholds and binaural loudness balances in a moderately noisy environment for a range of frequencies from 250 to 6000 Hz. Operator supervision required is minimal. The audiometer is constructed with a computer-assisted software engineering base called LabVIEW. Several user-aids are available from the virtual Front Panel of the instrument that contribute to the accuracy of the subject's determinations. The organization of the virtual instrument is illustrated and discussed. Sample data from four subjects of contrasting ages are included.... Auditory measurement, Instrumentation, Acoustic, Hearing.
