N2 - In this paper, we develope the high presence Sound Field Generation System using a power envelope inverse filter proposed by the author, with a pretreatment of Sound Field Generation System, and performed quantitative evaluation. In an experiment, reproduction signal was created approximating classical music by computer simulation. Consequently, an objective evaluation experiment showed an improvement in the results of approximately 2.7dB in the less than 4kHz band, and up to 8.6dB in the above 4kHz band.
