Aim of this study is to evaluate in ears with different kinds of perceptive disorders the relationships between Critical Ratio (CR), Remote Masking (RM) and Brief Tone Audiometry (BTA) in order to analyse to what extent cochlear efficiency depends on functional properties of the mechanical extrasensorial structures and/or of the sensorial elements in the inner ear. Present results show that in ears with non retrocochlear sensorineural losses CR results are more often affected than RM and BTA. A reduced cochlear efficiency is related more to a failure of the mechanical properties than to dysfunctions of the cellular elements within the inner ear; presumably, micromechanisms not yet understood or unknown interfere with the efficiency of the cochlea.
本研究的目的是评估不同类型感知障碍的耳朵中，临界比率（CR）、远程掩蔽（RM）和短纯音测听（BTA）之间的关系，以便分析耳蜗效率在多大程度上取决于内耳机械性超感官结构和/或感觉元件的功能特性。目前的结果表明，在非蜗后性感音神经性听力损失的耳朵中，CR结果比RM和BTA更容易受到影响。耳蜗效率降低更多地与机械性能的失败有关，而不是内耳细胞元件的功能障碍；据推测，尚未被理解或未知的微观机制干扰了耳蜗的效率。
