长期以来已经公认人对噪声损伤的敏感性有个体差异。过去由于受到暂时性阈移(TTS)这种研究方法的限制,一直未能成功地说明所谓“强耳”与“脆耳”之区别。近来,一些学者推荐用听觉过载试验(The Aural overload test)、倍频带掩蔽阈试验(threshold of octave masking[TOM]test)、短纯音测听法(Brief-toneaudiometry)和噪声中语言可懂度测验(Speechdiscrimination test in noise)等不同方法来评价由于噪声过强的刺激而导致内耳损伤的敏感性。听觉过载试验这种方法最初作为一种鉴别诊断试验。1973年Garhart提出这个试验对临床前的柯蒂氏器病理具有敏感性。听觉过载只是在适宜的刺激强度作用下在内耳发生的紊乱过程,可用耳蜗毛细胞生物电(GM)直接测定或通过心理
It has long been recognized that there are individual differences in sensitivity to noise damage. In the past, due to the limitations of the research methods such as the temporary threshold shift (TTS), the differences between so-called “strong ears” and “crispy ears” have not been successfully illustrated. Recently, some scholars recommend using the Aural overload test, the threshold of octave masking [TOM] test, the Brief-tone audiometry, and the speech intelligibility in noise test (Speechdiscrimination test in noise) and other different methods to evaluate the noise due to excessive stimulation of the sensitivity of the inner ear damage. Auditory overload test This method was originally used as a differential diagnosis test. Garhart in 1973 proposed that this test be sensitive to preclinical Coriolis pathogenesis. Auditory overload is only in the appropriate stimulus intensity in the process of disorder in the inner ear, available cochlear hair cell bioelectricity (GM) directly measured or through psychological
