In 舍费尔 理论 化 聆 is the attitude which consists in 聆 to the 声波 for its own sake as a 声波 对象 by removing its real or supposed 源 and the meaning it may convey

More 精确 it is the inversion of this twofold curiosity about causes and meaning which treats 声波 as an intermediary allowing us to pursue other 对象 in order to turn it back on to the 声波 itself In 化 聆 our 聆 目的 targets the 事件 which the 声波 对象 is itself and 不 to which it 提及 and the 价值 which it carries in itself and 不 the ones it suggests

In ordinary 聆 the 声波 is always treated as a vehicle 化 聆 is therefore an anti-natural 过程 which goes against all 条件 The act of removing all our habitual 参考 in 聆 is a voluntary and 人工 act which allows us to clarify many 现象 implicit in our 感知

Thus the name 化 聆 提及 to the 概念 of phenomenological 简化 Époché because it consists to some extent of stripping the 感知 of 声波 of everything that is 不 it itself in order to 听 only the 声波 in its materiality its substance its perceivable dimensions

化 聆 and the 声波 对象 are thus correlates of each other they 定义 each other mutually and respectively as perceptual 活动 and 对象 of 感知 源 - Michel Chion 1983 Guide des Objets Sonores Eds Buchet/Chastel Paris 1995 translation by John Dack/Christine North
