The elderly are difficult to have a smooth communication, because of their ears and brain declines with aging. In previous research, “technical listening training” has been proposed as a means of auditory-ability improvement. However, whether it is effect way to improve the speech intelligibility of the elderly was not studied yet. In this paper, we proposed a listening training method in order to improve the decline of the brain involved in the hearing of the elderly, and evaluated training effect through comparison with the adults. Listening training consists of five items of discrimination training (pitch, loudness, ITD, ILD, and the length of the sound). The training period is 15 days. Subjects consisted of five males in their 20s, and five males in their 70s. We compared their speech intelligibility before and after training. As a result, in the case of the younger adults, an improvement of about 10% was observed in SNR -15, -10 dB, and in the case of the elderly, an improvement of about 20% was observed in listening level 40, 50 dB.
