This study aims to investigate the impacts of acoustic environment on the relationship be-tween job characteristics and job satisfaction. Acoustic measurements and questionnaire sur-veys were conducted in open-plan offices in the UK and Korea. Background noise levels were recorded for 8 hours in each office and speech transmission index (STI) and sound pressure levels were measured for quantifying the single number quantities in ISO 3382-3. A total of 324 employees from 12 offices completed a questionnaire survey. The questionnaire included questions assessing noise disturbances and speech privacy, as well as job satisfaction and job characteristics. The result confirmed the strong impacts of job characteristics on self-rated job satisfaction. Background noise levels during working hours and reverberation time were negatively associated with job satisfaction; however, there were little influences of speech privacy and noise disturbance on job satisfaction. It was also observed that speech privacy, noise disturbance, background noise level, and cultural difference (Korea and UK) had moderating effects on the relationship between job characteristics and job satisfaction. In particular, greater speech privacy and lower background noise level increased the impacts of job characteristics on job satisfaction.
