Abstract: Many children, from 0 to 5 years old, spend most of their active hours in child day-care centers. Rooms in these centers are often very noisy due to voices of children and sounds of their various activities, enhanced by the excessive reverberation attributable to the little use of sound-absorbing materials in the room. Some researches have examined the speech intelligibility of elementary school pupils and the results show the score of the lower age group was the more affected by noise and long reverberation. It is expected that pre-school children could be even more affected than low-grade elementary pupils, but no study is found about this. Thus, in this study, experiments were carried out twice in actual classrooms of two child day-care centers with the participation of 3- to 5-year-old children to find the effect of acoustic condition on the word intelligibility of pre-school children.
