The purpose of this paper is to know the difference of response between the subjects with normal hearing and hearing impaired in reverberate sound fields. Experiments were carried on the subjects either with normal hearing or hearing impaired by tri-syllable articulation tests under the conditions of 0,1,2,4,6[sec] reverberation time. The result of this paper is as follows; 1. The articulation score of the aged is 25% less than the normal hearing in reverberante sound field. 2. Reverberation has disturbance and contribution to the 2nd and the 3rd syllable articulation score, 3. The result of tri-syllable articulation test cannot distinguish the difference among the experiment fields with above 2 second reverberation time, but the confusion rate of vowels in scores of the aged increase by reverberation time.
