Recall that the Stenger test is employed to investigate persons who have exhibited questionable unilateral hearing losses. The Temporal Speech Stenger was developed to enhance the effectiveness of a variation of the Stenger test which uses spondee words instead of pure tones as the stimuli. Spondee words were recorded on both tracks.
The first set of spondees was recorded simultaneously (diotic) while the second was recorded so that the spondees on one track lagged the other track by 2.25 milliseconds (dichotic). The effect is to maintain the intracranial sound image on the lead ear side as the interaural intensities are varied. As a consequence the patient does not perceive the shifting image that normally occurs as interaural intensities approach equality. In other words, the intensity/time of arrival (a special case of phase) trade-off is upset by delaying the onset of the spondee opposite from the claimed deafened ear. Thus a positive result is NO response.
