抄録

We propose an evaluation method that uses fractal dimension for the analysis of environmental sound. In previous studies, it was shown that the sense of hearing is able to identify fractal dimensions. Fractal dimension is therefore considered to be a useful parameter for the evaluation of acoustic environments. However, there are still many issues left to study, partly because fractal dimensions are not widely known about, and partly because they are affected by non-stationary sounds. In this report, we use the concept of entropy (which is widely used to evaluate quantities of information in the field of information theory) to demonstrate the effects of fractal dimensions on non-stationary sounds, and we investigate the validity of applying this knowledge to the analysis of acoustic environments.
