It is very important to explore the compound effect of heterogeneous environmental factors for improving the quality of living environment with popularization of electronic and/or information equipments. First, for an objective evaluation, three kinds of environmental factors: sound, illuminance and electromagnetic field of video (or visual) display terminal (VDT) are focused, especially from a stochastic viewpoint. From this experiment, some mutual correlation between sound and illuminance in peripheral environment of VDT was found. And also, another mutual correlation between electromagnetic field and illuminance environment of VDT was obtained. Secondly, for a subjective evaluation, three kinds of environmental factors: sound, temperature and illuminance are especially focused. If an optimum relationship among these environmental factors can be found, it seems that some improvements of our living environment can be discussed from psychological and/or stochastic viewpoint. From these studies, subjective and objective evaluation methods for room environmental factors will be considered.
