Abstract: The aim of this research is to determine the correlation between indoor noise and office productivity. Office productivity is measured by self-assessed approach. This subjective measurement of office productivity can be obtained by a question in the questionnaire. By investigating the importance of the sound factor among the environmental factors and the most annoying noise sources in the office, the research attempted to correlate human subjective feeling and the objective noise measurement. The study was conducted by a questionnaire survey to obtain the subjective measurement and the data were analysed by the statistical analysis programme -SPSS. It is found that temperature has the largest effect on office productivity. Office layout, sound and lighting are considered as second, third and forth important environment factors affecting productivity. However, air quality does not show significant effects on office productivity. Conversation, footsteps and phone ringing are the major noise sources affecting office productivity. A linear relationship is shown between the subjective feeling of sound and the objective measurement. The lower the noise level, the better the sound quality. Different age groups show different in office productivity including office layout, lighting, sound and especially. However, temperature and air quality show different influences on male and female. According to the results, most of the offices examined in this study did not fulfill the noise design criteria. It is suggested that noise effects should be carefully considered during office design which can be based on the international environment requirements such as HKBEAM or LEED.
