ABSTRACT:
An apparatus and method for screening an individual's ability to process acoustic events is provided. The invention provides sequences (or trials) of acoustically processed target and distractor phonemes to a subject for identification. The acoustic processing includes amplitude emphasis of selected frequency envelopes, stretching (in the time domain) of selected portions of phonemes, and phase adjustment of selection portions of phonemes relative to a base frequency. After a number of trials, the method of the present invention develops a profile for an individual that indicates whether the individual's ability to process acoustic events is within a normal range, and if not, what processing can provide the individual with optimal hearing. The individual's profile can then be used by a listening or processing device to particularly emphasize, stretch, or otherwise manipulate an audio stream to provide the individual with an optimal chance of distinguishing between similar acoustic events.
