The development of a satisfactory, automatic, self‐testing audiometric system (based on the pulse‐tone techniques suggested by Gardner, Harris, Reger and Newbyet al.) reveals the need for an investigation of the psychophysical procedures that might be used in such a system. Preliminary studies led to selection of four practical methods of threshold determination suitable for this project. Final choice of a single method requires a determination of statistical reliability as well as operational suitability of the method. Experimental apparatus was constructed to permit automatic testing by the four methods. Young adult subjects were tested with one of the four methods (randomly assigned) at three frequencies. A three‐dimensional experimental design, permitting the use of analysis of variance, furnished an estimation of variance to be assigned to factors in the design, and also measures of reliability for comparison of the four methods. The results contribute data needed for selection of the method to be used in a final practical version of an automatic, self‐testing system. [This work was supported by the U. S.
