To the Editor.—In the December 1985 issue of the Archives, Pearlman et al1 presented information regarding the validity of a commercially available sound-generating otoscope (Audio-Scope). The authors evaluated agreement between audiometric testing and the AudioScope but offered no test-retest data, ie, assessment of reliability or "repeatability" of measurements (as defined by Fletcher et al2).

Information necessary for more meaningful evaluation of the Audio-Scope was not included in the "Subjects and Methods" section. It would be important to know the total number of enrolled subjects, how many subjects had only one ear tested, the number of subjects in each hearing group, and the method of subject selection (eg, random, consecutive, or cooperative patients). It would also be important to know the sequence of test procedures for each subject, the method used to determine that sequence, and whether the test procedures were conducted by independent observers.
