초록

In this study, Noise was measured and its frequency size and characteristics were analyzed in office spaces. In order to improve the noise environment, the sound masking technology was used to extract and apply pink noise-based sound masking content suitable for it to obtain a noise reduction effect by improving the noise environment. As a result of this study, We think that the problem of spatial noise can be further improved and changed by mixing these sound masking systems as noise blocking facilities through appropriate harmony with interior facilities from architectural acoustics to construction. It was confirmed that there is an effect of improving the noise environment not only for blocking or improving external inflow noise, but also for various noises generated indoors, such as call centers.
