title: Reliability in the determination of speech reception threshold (SRT).
abstract: 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.
