Recently, due to the spread of the modern information technology, the closed interior space in the room and car, as if smog, have been filled with miscellaneous waves such as electro-magnetic, sound waves and so on. This problem seems to be related even to our information ethics, too. This is gradually becoming to the problem in every relationship of the world composed of the life and cultural environment, which have some inter-independence property with our will. In this study, first let us take the standing point that the primary property 'Relationism-First' on every environmental factors can be found in principle concerned first and after then, based on it, every type of inter-independence properties should be individually investigated as the secondary property. From this viewpoint, we had better to dare to choose the following way in the determination and measurement of the quantity for mutual relationship among all sorts of different environmental factors. That is, every linear and non-linear type multi-correlation analyses should be considered at the first stage of a study (i.e., for a search of truth). Only after then, by decomposing the compound effect into each factor according to our selected study purpose, the measurement and evaluation only for our specific interesting factor should be done. More concretely, for the compound and accumulation effects, at once, as a new trial we have proposed some evaluation method that will be a little more matched to the awareness of the above background idea, especially by limiting our study to the correlation problem between only two environmental factors of wave motion type. In this paper, we report the applied result of this method to the environment (especially on focusing sound and EM waves as environmental factors) around VDT with the attachment of tecnoAO to evaluate totally its effect.
