          Abstract

          Acoustical quality of the indoor environment is increasingly being recognized as important in commercial, residential and institutional building design. Unwanted sound is the most prevalent annoyance in many modern structures, leading to increased stress, loss of productivity and decreased quality of life for building occupants. The authors propose a minimum LEED standard for acoustical quality which can be incorporated into initial design or employed as a post-construction evaluation tool.

            Stress and open-office noise.

             G Evans,  D JOHNSON (2000)
            Forty female clerical workers were randomly assigned to a control condition or to 3-hr exposure to low-intensity noise designed to simulate typical open-office noise levels. The simulated open-office noise elevated workers' urinary epinephrine levels, but not their norepinephrine or cortisol levels, and it produced behavioral aftereffects (fewer attempts at unsolvable puzzles) indicative of motivational deficits. Participants were also less likely to make ergonomic, postural adjustments in their computer work station while working under noisy, relative to quiet, conditions. Postural invariance is a risk factor for musculoskeletal disorder. Although participants in the noise condition perceived their work setting as significantly noisier than those working under quiet conditions did, the groups did not differ in perceived stress. Potential health consequences of long-term exposure to low-intensity office noise are discussed.
