A new forced-choice procedure for measuring comfortable loudness for speech was evaluated on a group of 30 normal-hearing subjects. The test-retest reliability was determined for the forced-choice ascending and descending approach and found to be high (r = 0.83 and 0.84). Clinical reliability indicated that 80 to 83% of the subjects varied no more than 5 dB upon retest. In a second experimental session, comparisons between the forced-choice procedure and the method of limits (ascending and descending approaches) were evaluated on a group of 14 sensorineural subjects. Results indicated the forced-choice procedure eliminated the measurement differences found with the method of limits (ascending and descending approaches) and the forced-choice measurements remained stable across varying degrees and configurations of hearing loss. The procedure is fast, reliable, and has several advantages over the method of limits procedure.
对30名听力正常的受试者进行了一项用于测量言语舒适响度的新的强制选择程序评估。确定了强制选择升序和降序方法的重测信度，发现其较高（r = 0.83和0.84）。临床信度表明，80%至83%的受试者在重新测试时变化不超过5分贝。在第二个实验环节中，对14名感音神经性听力损失受试者进行了强制选择程序与极限法（升序和降序方法）之间的比较评估。结果表明，强制选择程序消除了极限法（升序和降序方法）中发现的测量差异，并且强制选择测量在不同程度和听力损失配置下保持稳定。该程序快速、可靠，与极限法程序相比具有多个优点。
