Ascending and descending procedures were used to obtain speech reception thresholds from 32 normal-hearing subjects whereas digits and spondee words were used as test materials. Comparisons of thresholds were made for the two procedures and materials. Results indicated that slightly lower (less SPL) speech thresholds resulted from the use of a descending procedure with both types of material. In addition, digit material was found to yield generally lower threshold values than spondees. Advantages to the use of the two procedures and materials are discussed.
采用升序和降序程序从32名听力正常的受试者中获取言语接受阈，同时使用数字和扬扬格词作为测试材料。对两种程序和材料的阈限进行了比较。结果表明，使用两种材料的降序程序时，言语阈限略低（声压级更低）。此外，发现数字材料产生的阈限值通常比扬扬格词更低。文中讨论了使用这两种程序和材料的优点。
