This study uses a structural equation model to examine the effects of noise on self-rated job satisfaction and health in open-plan offices. A total of 334 employees from six open-plan offices in China and Korea completed a questionnaire survey. The questionnaire included questions assessing noise disturbances and speech privacy, as well as job satisfaction and health. The results indicated that noise disturbance affected self-rated health. Contrary to popular expectation, the relationship between noise disturbance and job satisfaction was not significant. Rather, job satisfaction and satisfaction with the environment were negatively correlated with lack of speech privacy. Speech privacy was found to be affected by noise sensitivity, and longer noise exposure led to decreased job satisfaction. There was also evidence that speech privacy was a stronger predictor of satisfaction with environment and job satisfaction for participants with high noise sensitivity.In addition, fit models for employees from China and Korea showed slight differences.Practitioner Summary: This study is motivated by strong evidence that noise is the key source of complaints in open-plan offices. Survey results indicate self-rated job satisfaction of workers in open-plan offices was negatively affected by lack of speech privacy and duration of disturbing noise.

“…The questionnaire asked the office workers to rate their feeling towards the acoustical environment on an unbiased linear seven-point scale at the time the measurements were being done. The present adopted scale is similar to that used by Tang et al 5 and is shown in the Appendix. The rating obtained from the scale, which ranges from Ϫ3 to ϩ3, represents human auditory subjective rating.…”

“…4 However, most people today are working in air-conditioned office buildings whose facades have relatively higher sound transmission loss so that sound transmission from the outdoors to the indoors is insignificant when compared to those generated by the building services, such as the air-conditioning system, and human activities. 5 A good acoustical environment implies good control of noise to keep its level and frequency content within the acceptable range for human beings. This issue deals with human feeling, which is very subjective in nature.…”

Noise measurements and a questionnaire survey were carried out in air-conditioned landscaped offices in the present study in an attempt to find out what existing noise index gives the best correlation with the auditory sensation feeling of office workers. Results from statistical analyses show that the Equivalent Sound Pressure LEvel is the best among the 14 commonly used noise indices for this purpose. It is also found that the less commonly used Zwicker's loudness level performs better than the commonly adopted Noise Criterion curves and Noise Rating curves in predicting auditory sensation of office workers in air-conditioned landscaped offices. The performance of the 14 noise indices in predicting auditory comfort are compared.

“…22,23 The studies by Tang et al also found L Aeq to be generally well correlated with subjective auditory sensation, with other metrics performing well in certain circumstances. [18][19][20][21] Tang and Wang noted that many of their measured spectra contained some degree of tonality, but a detailed investigation of such was not the focus of their work. 21 Despite these previous studies generally supporting L Aeq , other studies have demonstrated limitations in the metric.…”

Implications of human performance and perception under tonal noise conditions on indoor noise criteria

This research investigated differences in task performance and perception under six non-time-varying ventilation-type background noise spectra with differing tonality. The results were related to five indoor noise criteria systems: noise criteria, balanced noise criteria, room criteria, room criteria mark II, and the A-weighted equivalent sound pressure level ͑L Aeq ͒. These criteria systems are commonly used in the U.S. building industry, but concerns exist over whether they are appropriate for all noise situations. Thirty test subjects completed three types of performance tasks ͑typing, reasoning, and math͒ and answered questions about their perception of the indoor environment under each noise condition. Results showed that performance scores did not change significantly across the six noise conditions, but there were differences in subjective perception. For example, perception trends for tonality, annoyance, and distraction changed based on the frequency and prominence of discrete tones in noise. However, these perceptual changes were not fully reflected in the criteria level or spectral quality ratings. Additionally, task performance was related to subjective perception but not to criteria level predictions. As a result, the authors suggest that the current criteria should be modified to account for the frequency and prominence of tones in background noise.
