Provided are a sound generation system and a sound recording system, which are placed in a room to adjust sound. A columnar body is disposed around a sound source to adjust how much sound of a low-tone range, as well as of a middle- and high-tone range, is absorbed and diffused. Moreover, a columnar body is disposed around a recording device to adjust how much sound of a low-tone range, as well as of a middle- and high-tone range, is absorbed and diffused. The columnar bodies may be made of a combination of different diameters and/or lengths. The arrangement distances may be random. With the columnar body disposed at the most appropriate location, it is possible to adjust sound in a wide band.
