| Research Abstract |
We take a position that all sound is reconsidered as "an environment sound" by this research. Then it is separated "an environment sound" into a "living environmental sound (artificial acoustic source)" and a "natural environmental sound (non-artificial acoustic source)" by a kind. Specially, there were a few observation cases for the "natural environmental sound", generally an observation method and an evaluation method aren't decided at present.
A noise measurement is used for the observation of the natural environment sound in the natural forest (the rich space of the natural environment). In addition, it is investigated about a sound structure by a tree cesus and a topographical survey. The equivalent noise level which was easy to compare with a living environment sound was adopted as a value of the evaluation of the natural environment sound.
Three observation points are installed in the investigation applicable area. We could grasp a characteristic and a variance about the equivalent noise level from the result of three fixed-point observations. By these results, the possibility of index-ization was suggested. About grasping of the sound structure in a forest, a possibility of clustering is suggested by an analysis of the forest stand which was investigate by the tree census in field of forest science.
