In order to clarify the current situation on classroom acoustics for hearing impaired students, we performed a survey through nationwide questionnaires and acoustic measurement in elementary and junior high schools. First, the nationwide questionnaires for teachers revealed their awareness to classroom acoustics, diversity of architectural specification of classrooms, and a variety of sounds interfering with students' hearing. Secondly, acoustic measurement was performed at 6 typical schools, which were selected on account of architectural specification and construction age. It showed the distribution of acoustic performance of special instruction rooms and normal classrooms regarding reverberation time, sound insulation between rooms, and indoor ambient noise. Finally, we discussed the measured results in comparison with the standards recommended by overseas governments and AIJ.
