We present an experiment that investigated the effect of vibrotactile stimulation in auditory pitch discrimination tasks. Extra-auditory information was expected to have some influence upon the frequency discrimination of auditory Just Noticeable Difference (JND) detection levels at 160 Hz. To measure this, the potential to correctly identified positive and negative frequency changes for two randomly divided groups was measured and then compared. The first group was given an audio only JND test and the second group was given the same test, but with additional vibrotactile stimulus delivered via a vibrating glove device. The results of the experiment suggest that in musical interactions involving the selection of specific pitches, or the detection of pitch variation, vibrotactile feedback may have some advantageous effect upon a musician's ability to perceive changes when presented in synchrony with auditory stimulus.
我们展示了一项实验，该实验研究了振动触觉刺激在听觉音高辨别任务中的作用。预计额外的听觉信息会对160Hz时听觉最小可觉差（JND）检测水平的频率辨别产生一定影响。为了对此进行测量，我们对两个随机分组的正确识别正、负频率变化的能力进行了测量，然后进行比较。第一组仅进行音频JND测试，第二组进行相同测试，但通过振动手套设备提供额外的振动触觉刺激。实验结果表明，在涉及特定音高选择或音高变化检测的音乐互动中，当与听觉刺激同步呈现时，振动触觉反馈可能对音乐家感知变化的能力产生一些有利影响。
