A hypothesis is offered to account for the fact that in functional hearing loss, spondee threshold is frequently significantly lower than the pure-tone average. The hypothesis has three basic components: (1) that patients with functional hearing loss use a loudness criterion in making response decisions to suprathreshold stimuli; (2) that, at suprathreshold levels, pure tones and spondee words appear equally loud at equal sound pressure levels, and (3) that calibration values employed in pure-tone and speech audiometry contribute to the aberrant speech-pure tone relationship. Factors that may confound the speech-pure tone relationship are discussed as are the clinical and research implication of the hypothesis.
针对功能性听力损失中,pondee词阈常常显著低于纯音平均听阈这一事实,本文提出了一个假说。该假说有三个基本要素:(1)功能性听力损失患者在对阈上刺激做出反应决策时采用响度标准;(2)在阈上水平,纯音和pondee词在等声压级时听起来同样响亮;(3)纯音听力测试和言语听力测试中使用的校准值导致了异常的言语-纯音关系。文中讨论了可能混淆言语-纯音关系的因素以及该假说的临床和研究意义。
