In order to investigate the acoustical problems in open-plan type elementary schools, field measurements and observation/inquiring surveys were performed for several schools of this type. From the results, it has been found that the sound environment in classrooms is determined by such factors as the acoustical properties of school buildings, situation and characteristic of each school, the activity of class works, and awareness of the teachers and children to the sound environment. Based on these findings, questionnaire survey was designed and conducted with teachers in eight schools. From the results, the acoustical conditions in open-type classrooms are discussed and the way of improving them is considered.
