论文摘要
听力通常被认为比触摸更敏感。该断言是基于对弱刺激的敏感性的比较。但是，各自的刺激不容易比较，因为使用声压力和使用皮肤位移来触摸听力。我们表明，在合理的假设下，听觉和触觉检测阈值可以在水平的竞争环境中进行调解。结果表明，触摸和听力检测弱刺激的能力会根据感应物体的大小以及其振荡的频率而变化。特别是，发现触摸比检测小物体和缓慢的物体时的触摸更有效。
Hearing is often believed to be more sensitive than touch. This assertion is based on a comparison of sensitivities to weak stimuli. The respective stimuli, however, are not easily comparable since hearing is gauged using acoustic pressure and touch using skin displacement. We show that under reasonable assumptions the auditory and tactile detection thresholds can be reconciled on a level playing field. The results indicate that the capacity of touch and hearing to detect weak stimuli varies according to the size of a sensed object as well as to the frequency of its oscillations. In particular, touch is found to be more effective than hearing at detecting small and slow objects.
