Effects of Auditory Pre-Stimulation on Cognitive Task Performance in a Noisy Environment

The accident rate due to human errors in industrial fields has been consistently high over the past few decades, and noise emerging as one of main causes errors. In recent years, auditory pre-stimulation considered a means preventing by improving workers’ cognitive task performance. However, most previous studies demonstrated effectiveness quiet environment. Accordingly, on effects noisy environment are still lacking. Therefore, this study aimed empirically investigate: (1) environments performances tasks related different functions working memory (2) field-noise To accomplish these research objectives, two major experiments were conducted. first experiment, total 24 participants performed each three basic short-term/working (STM/WM) under experimental conditions (quiet-noise environment) depending presence or absence field noise. second STM/WM after they provided with four pre-stimulations (quiet noise, white mixed (white field) noise). Corsi block-tapping, Digit span, 3-back tasks, corresponding visuospatial sketchpad, phonological loop, central executive WM, respectively. findings that: did not affect scores block-tapping significantly affecting only span score (decreased 15.2%, p < 0.01); performance was improved 17.9% (p 0.05) when type pre-stimulation. These may be useful for work-space designs that prevent/minimize accidents workers environments.
