This report describes a simplified suprathreshold tone decay test procedure (STAT). The sustained test signal is presented for 60 seconds at 110 dB sound pressure level. The patient is asked to respond as long as he hears the sound. If the patient responds for the full 60-second test period, the result is negative. If, however, he fails to respond for the full 60 seconds, the result is considered positive for eighth-nerve site.
Clinical experience with the new test procedure suggests that it minimizes false alarms without sacrificing accuracy of identification of eighth-nerve site.
