Clinical measurements of the speech reception threshold (SRT) have been made in order to determine the parameter values of a psychometric function. SRT measurements were then simulated in a computer to obtain, among other things, the standard deviation of a number of measurements from one and the same "patient". "Patients" with poor speech discrimination resulted in bad reliability of the SRT and great sensitivity to the hearing level at which the test started. New methods are proposed here, which are both faster and less susceptible to influence from the patient's speech discrimination.
为了确定心理测量函数的参数值，已对言语接受阈（SRT）进行了临床测量。然后在计算机中模拟SRT测量，以便除其他外，获得来自同一个“患者”的多次测量的标准差。言语辨别能力差的“患者”导致SRT的可靠性差，并且对测试开始时的听力水平非常敏感。本文提出了新的方法，这些方法既更快，又更不易受到患者言语辨别能力的影响。
