Five blind subjects were provided with an auditory "mirror" of their facial activity by transducing myoelectric signals from facial muscles into sound. Expressions of happiness, surprise, and anger were defined primarily by involvement of the zygomaticus, the frontalis, and the corrugator, respectively. These muscles were connected through separate voltage-controlled oscilllators to separate loudspeakers, such that each muscle activated a different speaker. Motion pictures taken before and after training were assembled in random order and were shown to preselected judges who attempted to identify the expressions. The judges were correct significantly more often on the posttraining expressions. Appropriateness and adequacy of expressions, as rated by the judges, also improved significantly as a result of training.
通过将面部肌肉的肌电信号转换为声音，为五名盲人受试者提供了其面部活动的听觉“镜像”。快乐、惊讶和愤怒的表情分别主要由颧肌、额肌和皱眉肌的参与来定义。这些肌肉通过单独的压控振荡器连接到单独的扬声器，这样每块肌肉就会激活一个不同的扬声器。训练前后拍摄的电影以随机顺序组合，并展示给预先选定的评委，评委们试图识别这些表情。评委们对训练后表情的判断正确率显著更高。评委们评定的表情的恰当性和充分性也因训练而显著提高。
