Clinical considerations in the use of time-compressed speech

The four lists of the Auditec of St. Louis recording of the 60% time-compressed NU 6 test were presented at 32 dB SL to 28 normal subjects and 28 subjects with sensorineural hearing loss. Significant list effects were found, with only lists I and IV being equivalent for both groups. A significant learning effect, greater for the normal subjects, also was present. Clinical recommendations are made regarding list and practice effects and considerations for use of this test in the presence of peripheral hearing impairment.
