“…[3,78] Further support for the detrimental effects of long-term exposure on Stroop performance comes from a study which showed longer executive times in the colorname Stroop task in long-term noise exposed traffi c police offi cers, compared to control offi ce workers. [50] In addition to the duration of noise, the content of noise is also important as suggested by the fi nding that high affect music and everyday noise are signifi cantly more detrimental to Stroop performance compared with silent and low affect music conditions.

Noise stress (NS) is detrimental to many aspects of human health and behavior. Understanding the effect of noise stressors on human cognitive function is a growing area of research and is crucial to helping clinical populations, such as those with schizophrenia, which are particularly sensitive to stressors. A review of electronic databases for studies assessing the effect of acute NS on cognitive functions in healthy adults revealed 31 relevant studies. The review revealed (1) NS exerts a clear negative effect on attention, working memory and episodic recall, and (2) personality characteristics, in particular neuroticism, and sleep influence the impact of noise stressors on performance in interaction with task complexity. Previous findings of consistent impairment in NS-relevant cognitive domains, heightened sensitivity to stressors, elevated neuroticism and sleep disturbances in schizophrenia, taken together with the findings of this review, highlight the need for empirical studies to elucidate whether NS, a common aspect of urban environments, exacerbates cognitive deficits and other symptoms in schizophrenia and related clinical populations.

“…P300 is considered to reflect cognitive neuroelectric phenomena; its amplitude is considered to reflect the amount of cognitive resource allocation and the process efficiency, and its latency is considered to reflect the time needed for evaluation of stimuli 9) . P300 can be used to examine the cognitive function in the workplace; Chiovenda et al 10) used P300 to examine the influence of traffic noise on traffic police officers. The results showed a wider P300 amplitude reduction in traffic police officers than in controls under noisy conditions, suggesting that occupational noise exposure has chronic effects on cognitive functioning and underlying cognitive processing.…”

The purpose of the present study was to compare the physiological responses to different types of mental stress encountered in the workplace. Circulatory and central nervous system responses were examined in 8 healthy males by exposing them to 20-min of white noise (80 dB(A)) and 20-min of computer-based mental arithmetic tasks as models of vascular and cardiac stress, respectively. The results indicated that both cardiac and vascular stresses increased blood pressure and showed a cumulative effect as exposure period was extended. Heart rate and prefrontal oxygenated hemoglobin levels (measured by NIRS) increased in the face of cardiac stress but were not clearly altered by vascular stress and indicated that cardiac stress higher cardiac response and requires more oxygen supply to the brain. As the central nervous system responded, an event-related potential P300 component was elicited by an auditory oddball task presented before and after each stress. The P300 amplitude increased for both stresses. However, P300 latency increased in response to cardiac stress but decreased with vascular stress in the left prefrontal. Thus, the circulatory and central nervous system responses to cardiac stress and to vascular stress may have different underlying mechanisms, and measuring physiological indices appears to be an effective method by which to evaluate the influence of mental stress.

“…In usual circumstances of these working environments, occupational noise is a usual condition of long-term and higher than 80dB of noise exposure, continuously generated from the working environments in every day and whole time of the working hours 12 . The consequent chronic noise exposure in occupational noise environment physically damage to the hearing of workers and critically affects their susceptibility in the noiseinduced stress and their quality of life 18,19 . The audiometry results, especially in the industry and education, were revealed that the workers who suffered from inner ear disorders were significantly higher than other occupational groups 16 .…”

Background: Noise pollution has been called an invisible killer. It has been a critical issue for the people working in the noisy environments especially in industry and education. This study was conducted to evaluate the differences of neuronal activity between groups, an experimental group is profession in occupational noise environments and a control group is who did not, and all of the subjects had tinnitus or hyperacusis. We used the electroencephalography data from 17 patients. The two experimental subjects were a tinnitus patient and a hyperacusis patient. The fifteen control subjects were seven tinnitus and eight hyperacusis patients and all of the subjects had normal hearing.Results: We compared the brain activity for three states among the groups: after noise-induced state and no sound exposure state for the two experimental subjects, and no sound exposure state for the control group. The activity of the auditory cortex in the experimental group after noise exposure were significantly increased in gamma (p = 0.002) and decreased in delta and theta band. In other brain areas, the rates of the delta, theta, beta 1~3 and gamma for the control group were higher than the experimental subjects for both with or without noise exposure states.Conclusions: Through this study, it was suggested that the professions of tinnitus and hyperacusis with normal hearing in occupational noise environment could be maintain their pathological states by abnormal hyper-activation of the primary and secondary auditory cortex alone.
