Fifteen cases (group A) with excellent, and 15 cases (group B) with poor score, of discrimination for filtered speech were selected out of 49 cases (98 ears) whose hearing level was within 30 dB at the speech frequencies.
Number of correct answer was recorded for each monosyllable speech sound. Monosyllables which showed good discrimination in group A and poor discrimination in group B were selected and listed.
The new list consisted of seventeen 1, 700Hz-low-pass-filtered monosyllables and three 1, 200Hz-low-pass-filtered monosyllables.
By computing the amount of information obtained by the new list and the correlations of the new and the 57 AB list it was found that the new list was more sensitive and useful for the diagnosis of hearing disorders than the 57-AB list.
