Cost-Benefit Analysis of Two Decision Criteria for Spondee Threshold Measurements Normal-hearing subjects were tested and retested using two spondee threshold criteria: a strict 50% correct rule and a 50% or 75% correct (or both) rule. The 50% criterion produced lower thresholds at the cost of poorer test-retest reliability and longer test durations. Both decision rules gave lower threshold SPL values ... Research Article

Normal-hearing subjects were tested and retested using two spondee threshold criteria: a strict 50% correct rule and a 50% or 75% correct (or both) rule. The 50% criterion produced lower thresholds at the cost of poorer test-retest reliability and longer test durations. Both decision rules gave lower threshold SPL values and required less testing time during the second trial. A proposed benefit-cost ratio model indicated that the 50% or 75% (or both) decision rule gives a better return on the investment of clinical effort.
