从1977年纽约大停电前一个小时开始，爱迪生联合公司的系统操作员（SO）和他的上级（CSO）的电话录音被用来分析心理压力的迹象。(SO负责监控和切换Con艾德网络内的电力负载。）从两个人的话语进行了分析，产生几个音调和幅度的统计。为了评估压力的感知相关性，四组听众使用了七点量表来评价随机发声或随机发声的转录的SO和CSO的压力。结果表明，而CSO的音高增加显着增加的情景压力，SO的音高下降。从声音中获得的压力等级与平均音高呈正相关。听众对心理压力的刻板印象似乎包括音调和振幅水平的升高，以及它们的可变性增加。
Tape recordings of telephone conversations of Consolidated Edison's system operator (SO) and his immediate superior (CSO), beginning an hour before the 1977 New York blackout, were analyzed for indications of psychological stress. (SO was responsible for monitoring and switching power loads within the Con Ed network.) Utterances from the two individuals were analyzed to yield several pitch and amplitude statistics. To assess the perceptual correlates of stress, four groups of listeners used a seven-point scale to rate the stress of SO and CSO from either randomized vocal utterances or transcripts of the randomized utterances. Results indicated that whereas CSO's vocal pitch increased significantly with increased situational stress, SO's pitch decreased. Listener ratings of stress from the voice were positively related to average pitch. It appears that listener's stereotype of psychological stress includes elevated pitch and amplitude levels, as well as their increased variability.
