The purpose of the present study is to analyze the characteristics of the living room space that provides comfortable environment for the infants and family members from the aspect of sound. This study focuses mainlyon the evaluation of the sound characteristics of the living space that support and maintain the development of verbal communication ability that can be cultivated significantly by the interaction between the infants and the parents.In this year, we directed our attention to the infant crying and study the relationship between the living space and the sound characteristics. We investigated the actual conditions of the sound pressure level (dB) and sound pitch (Hz) inherent to the infant crying. A total of 28 pairs of infants and mothers or fathers, two months to one year and 11 months in age, participated in the measurement. We recorded the infant crying at the site one meter apart from the infant's mouth in an anechoic room. The measurement data were analyzed and four patterns of sound characteristics were detected. The infant crying characterized by the high-frequency component and the large volume was recognized as a crying indicating increased emergency and appeared to have considerable effects on the surroundings. In this experiment, we take an approach to relate the parent's pattern of hearing of the infant crying with the sound environment inside of the room.The results of this study contribute to the process of remodeling of the living space, and to suggest for the recent childcare related problems including of child abuse.
