Under the objective to determine the factors which influence comprehensive evaluation of housings, we have focused on the sound environment and how the extent of its effect is perceived by the affected residents. The results of POE, a comprehensive collection of elements involved in the evaluation of dwelling environment, and responses to the survey we have recently conducted on the influence of sound environment on people living in public multi-family dwelling were compiled before being analytically evaluated under classII numerical theory. The analysis indicates that factors such as the size of the residence, privacy and commuting time, as well as level of noise heard from the floor above affect the evaluation of dwelling environment greatly. Residents perception and the degree of satisfaction on sound environment are influenced by their daily experiences and comparisons to housings they have dwelled in the past. The data reveals that factors related to conditions required to dwell in apartments such as certain rules and restrictions and association with the neighbors also give considerable influence to the degree of satisfaction.
