Based on demographic prognoses, it must be assumed that a greater number of older workers will be found in the future labor market. How to deal with their possible age-related impairments of sensory functions, like hearing impairment and work performance during extended working time, has not been addressed explicitly until now. The study addresses this interplay. The study was performed on two consecutive days after normal working hours. The 55 participants had to "work" in the study at least three additional hours to simulate a situation of long working hours. The tested measures for (job) performance were: general attention, long-term selective attention, concentration, and reaction time. All of the investigated variables were taken at both days of the study (2 × 2 × 2 repeated measurement design). The results show effects for age, the interaction of hearing impairment and time of measurement, and effects of the measurement time. Older participants reacted slower than younger participants did. Furthermore, younger participants reacted more frequently in a correct way. Hearing impairment seems to have a negative impact especially on measures of false reactions, and therefore especially on measurement time 1. The results can be interpreted in a way that hearing-impaired participants are able to compensate their deficits over time.
基于人口预测，未来劳动力市场中将会有更多的老年工人。迄今为止，尚未明确如何应对他们可能因年龄而导致的感官功能（如听力障碍）和长时间工作时的工作表现下降等问题。本研究探讨了这种相互作用。该研究在正常工作时间后连续两天进行。55 名参与者必须在研究中至少额外工作三个小时，以模拟长时间工作的情况。（工作）表现的测试措施包括：一般注意力、长期选择性注意力、注意力集中和反应时间。所有调查变量都在研究的两天内进行（2×2×2 重复测量设计）。结果表明年龄有影响，听力障碍和测量时间的相互作用有影响，测量时间也有影响。年长的参与者比年轻的参与者反应慢。此外，年轻的参与者更频繁地以正确的方式做出反应。听力障碍似乎尤其对错误反应的测量有负面影响，因此尤其对测量时间 1 有负面影响。结果可以解释为听力受损的参与者能够随着时间的推移补偿他们的缺陷。
