This study is a report of the result of investigating the sound environment at setting childcare scene in nursery institutions focused on children's learning activity aiming to make the acoustic environment as their learning field. By the behavioral observation and the sound field analysis at activity scene, we observed the characteristic of sound field at each study scene and the change of the acoustic environment when the teacher was setting the learning environment.
The result shows that the sound by the children's behavior was a keynote source at dynamic activity scene like singing and dancing. Especially, the level of 1-2kHz band by children's voice and low frequency sound was characteristic. And for making settled space that was attached weight in young children's educational field, teachers often used the sound factor by the setting environment scene and a moderate silence was a very important environmental factor. For acoustic design according to the educational purpose, many-sided investigation of the sound space was essential to understand the teacher's setting behavior and children's behavioral pattern.
