실내조경에 사운드스케이프 음원 제공시 재실자의 음환경 만족도 향상에 관한 연구

This study was focused on the influence of soundscape provided to the interior landscape on the improvement of occupants' sound environment. When soundscape was provided to occupants together with the interior landscape rather than simply providing interior landscape, the occupants' satisfaction seemed to be improved. The most preferred sound source among the three sound sources was considered as the sound of the grasshopper. When both of the interior landscape and the landscape substances was provided, the adjectives with the average difference of more than 1 are 'Vicissitudinous', 'Elegant' and 'Cheerful'. When the interior landscape and the sound source were provided, such adjectives as 'Vicissitudinous', 'Complex' and 'Cheerful' are extracted. When all the variables were provided, such adjectives as 'Vicissitudinous', 'Abundant' and 'Cheerful' seem to show the difference of more than 1. Regarding 'Vicissitudinous', it was possible to know that the average difference of more than 1.5 was the biggest. Regarding the relative values of the ${\alpha}$ wave and the ${\beta}$ wave for each part, it seemed that the highest ${\alpha}$ wave was generated on the left parietal lobe of P3, while the lowest ${\beta}$ wave was generated on the left and right frontal lobes of Fp1 and Fp2. According to this study, it was shown that the soundscape and the interior landscape seemed to influence the improvement of the occupants' sound environment.
