The open-plan office has been widely used all over the world since 1970s', and its quality of environment affects the health and efficiency of many workers. One of the dissatisfaction of office workers focuses on the acoustical environment. To be economical, the interior design often omits acoustical treatment, which results in a noisy, less private and chaotic environment. First of all, this paper discusses the specialties and tendency of acoustical environment in open-plan office, and decides to take noise-control and speech-privacy-achieving as the key points of acoustic study. Chap.2 analyzes the noise lever of open-plan office, and provides measures to control noise in total planning, sound insulation and sound absorption. Chap. 3 thoroughly expounds every factor affecting speech-privacy in open-plan office. With the help of the mathematical model and the applied software, chap.4 analyzes the acoustical environment in open-plan office quantificationally, and give a theoretic forecast to its effects. At last, this paper summarizes all the experience and theory, and through field survey, puts forward the steps of architecture acoustic design systematically, which can be referred by architects and interior designers.
