在异常响度反应的情况下，研究了先前确定的时间阈值和响度之间的关系。通过时间阈值测量和双耳响度匹配，在完全募集的病理情况下，建立了关于改变功能性质的一般原则，结果如下：（1）在阈值以上的恒定水平下，以分贝为单位的听力损失与由L/I值确定的病理性响度增加程度的对数有关;（2）对于一定的听力损失，响度-增量度的L/I值随阈上声级的对数增加而线性减小;（3）时间-阈测定的图形结果与响度匹配的图形结果直接连续，本研究结果将先前测定的响度-时程关系的有效性扩展到异常响度反应。在掩蔽条件下实验诱发的异常响度反应证实了这一结果。
The previously determined relation between time‐threshold and loudness is investigated in cases of abnormal loudness response.General principles concerning the nature of the altered function are established in pathologic cases with complete recruitment by time‐threshold measurement and by binaural loudness matching with the following results: (1) at a constant level above threshold, the hearing loss in decibels is related to the logarithm of the pathologic degree of loudness increment, as determined by L/I values; (2) for a given hearing loss, the L/I value of the loudness‐increment degree decreases linearly with the logarithmic increase of the level above threshold; (3) the graphic results of time‐threshold determination appear directly continuous with those of loudness matching.Present findings extend the validity of previously determined loudness‐duration relations to abnormal loudness responses. Experimentally induced abnormal loudness response under conditions of masking confirms the results.In cases...
