The effect of office noise on functionality has lately been the topic of much disagreement. Several studies have attempted to objectively measure the effect of sound on office operation, but no consensus was reached. Studies have attempted to test the impact of ambient noise on degrees of alertness and fatigue, but the results are combined. A range of researchers report that the results are consistent across a large number of categories, but conclusions are often controversial. A unique laboratory test (EQ-i) was developed for the experimental evaluation of office noise. The test has been demonstrated to be a trusted tool for measuring the effect of noise on workplace productivity.
The EQ-i is based on two elements. 1 part measures the cognitive processing of workplace workers, while another element measures the subjective reaction of office workers to various visual stimuli. The testing process is performed in a quiet area with the noise of a personal computer turned off. A battery of tests is performed on a particular group of office employees. A subjective questionnaire is also carried out on each person to obtain information in their working habits and opinions about the office environment. Following a series of evaluations are conducted on a random sample of workplace personnel, a mean total score is calculated for each individual.
Several other explanations have been advanced to account for the results of the EQ-i results. Potential explanations are that office employees were not subjected to sufficient substantial intensity or low intensity sound during the testing period, workplace equipment was malfunctioning or inaccurate, or the results were skewed due to several confounding factors. No alternative explanation has yet to be offered that can clarify the results obtained from this evaluation.
A test study was conducted to determine the association between ambient temperatures and indoor lighting in a health setting. Researchers measured indoor lighting in four distinct points in the office space and found a strong and significant relationship between both. The investigators attributed this relationship to the effect of light on employee's moods. Indoor temperature was found to be negatively associated with the disposition of office workers as evidenced by a statistically significant increase in anxiety levels. The authors concluded that"the present review... indicates that there is a negative relationship between ambient temperature and disposition among office employees."
In another study, researchers examined the effect of reddish blue light on neurobehavioral testing. They quantified neurobehavioral testing at a dimly-lit area and 오피스텔 found no difference in performance between states. However, the researchers stressed the importance of using an appropriate neurobehavioral testing protocol and performing standardized psychological tests in clinical settings. They also highlighted that more studies must be done to examine the impact of low lighting on neurobehavioral testing.
A third research project attempted to assess the effect of temperature on reaction time in a lab setting. Researchers measured reaction time at a dimly-lit space and discovered that the reaction time increased if there was an increase in room temperature. But they worried that this was not a substantial impact and was affected by the existence of other aspects. For instance, a small increase in temperature decreased the amount of beta activity. What's more, the researchers emphasized that the effect of temperature on the reaction time could have significant consequences for executive function test.
The fourth research project tested the effect of temperature on executive function in an environment with two distinct light-sensitivity levels (daylight or dark). Two office workers, one with a day/night preference and the other with a no-light preference, engaged in a task where their performance was analyzed using a reaction time paradigm. After finishing the job, the performance of the two office workers was compared. The results showed a significant main effect of temperature on the response time (p = 0.049). The authors concluded,"A distinct window of temperature advantage may contribute to executive processing speed" This study showed that temperature did really have a favorable impact on reaction time when it was commanded for neighboring lightness or darkness.
In general, these studies confirm the importance of temperature for work performance. Specifically, they show that temperature can modulate numerous aspects of performance such as attention, mood, alertness, and mental functioning. Office workers are particularly susceptible to temperature fluctuations, which is likely because of the inherently challenging nature of the job that involves sitting in front of a monitor or working with extreme lighting conditions.
