摘要

听力损失会损害美国陆军飞行员的表现、安全和态势感知能力,导致精神负荷和听力努力的增加。本研究评估了模拟听力损失对陆军飞行员表现和认知负荷的影响。方法:采用混合效应线性回归研究设计。共有21名飞行员接受了临床听力学测试和模拟飞行性能评估。模拟听力损失和工作负荷对语音识别、飞行表现和主观工作负荷的影响。飞行模拟路线包括高负荷和低负荷的正常听力和模拟听力损失情况。工作负荷问卷被用于主观工作量评估,并在不同条件下进行比较。结果:语音识别评分随听力损失程度的增加而下降。在高负荷条件下,飞行中的语音清晰度下降,轻度听力损失下降26%,严重听力损失下降40%。高工作负荷条件降低了飞行性能和对次要任务的响应时间,模拟听力损失加剧了这种情况。工作量评分证实了模拟听力损失增加了工作量。在听力评估方面没有观察到显著的发现。讨论:研究结果表明,听力损失会对语音识别和飞行性能产生负面影响,特别是在高工作量下。这些结果支持了解决飞行员听力损失问题的重要性。临床上适用的改良押韵测试是否能反映听力损失对飞行员表现的影响,还需要进一步的研究。Noetzel J, Henry P, Mackie R, Cave K, Stefanson JR, Hale JK, Andres K, Jones H.模拟听力损失对飞行员语音识别、飞行表现和工作负荷的影响。航空航天Med Hum Perform. 2025;96(4): 269 - 278。

Simulated Hearing Loss on Speech Recognition, Flight Performance, and Workload in Aviators.

Introduction: Hearing loss can compromise U.S. Army aviators' performance, safety, and situational awareness, resulting in increasing mental workload and listening effort. This study evaluated simulated hearing loss on performance and cognitive workload among Army aviators.

Methods: A mixed-effects linear regression study design was used. A total of 21 aviators underwent clinical audiological testing and simulated flight performance assessments. Simulated hearing loss and workload were manipulated to investigate their effects on speech recognition, flight performance, and subjective workload. Flight simulator routes included normal hearing and simulated hearing loss conditions for both high and low workloads. Task load questionnaires were administered for subjective workload assessments and compared across conditions.

Results: Speech recognition scores decreased with increasing levels of hearing loss. In-flight speech intelligibility declined in high workload conditions, with a 26% decrease for mild hearing loss and a 40% decrease for severe hearing loss. High workload conditions degraded flight performance and response times to a secondary task which was exacerbated by simulated hearing loss. Workload scores validated increased workload with simulated hearing loss. No significant findings were observed on the hearing assessment.

Discussion: Findings suggest hearing loss negatively impacts speech recognition and flight performance, especially under high workloads. These results support the importance of addressing hearing loss in aviators. Further research is needed to determine if the clinically adapted Modified Rhyme Test can reflect the impact of hearing loss on aviator performance.
