Abstract

In the course of the experimental laboratory studies it was found out a significant impairment of the communication following a 2-hour processing of speech signals in conditions of masking noise. In order to diminish the auditory exhaustion in impeded communication the authors created physiologically grounded model of the working and resting regime in accordance to the experimental data, which require the including of two breaks in the first half of the working day, i.e. after a two hour exposition to masking noise. The minimal duration of the break at the end of the second hour (according to the experimental data) must be not less than 10 minutes in order to reach the initial or near to it speech communication. The time of the second break may coincide with the regulated lunch-time. The created working and resting regime was approbated in working conditions at DF "Kremikovtsi". It was found out that following the introduction of the physiological regime of work and rest, the auditory exhaustion decreased which was expressed in lowering of the rate of tone-intensity steps.

[时间对语言交流的卫生人体工程学保护]。
在实验室的实验研究过程中,发现在掩蔽噪声条件下对语音信号进行2小时处理后,通信出现了明显的损伤。为了减少沟通障碍时的听觉疲劳,作者根据实验数据创建了工作和休息制度的生理基础模型,该模型要求在工作日的前半个工作日中包括两次休息,即在掩蔽噪声暴露两小时后。第二小时结束时的最小休息时间(根据实验数据)必须不少于10分钟,才能达到初始或接近初始的语音交流。第二次休息的时间可以与规定的午餐时间一致。所建立的工作和休息制度在“Kremikovtsi”DF的工作条件下得到认可。研究发现,在引入工作和休息的生理机制后,听觉疲劳有所减少,表现为音调强度步骤的速率降低。
