Sound is sensed by the ear but can also be felt on the skin, by means of vibrotactile stimulation. Only little research has addressed perceptual implications of vibrotactile stimulation in the realm of music. Here, we studied which perceptual dimensions of music listening are affected by vibrotactile stimulation and whether the spatial segregation of vibrations improves vibrotactile stimulation. Forty-one listeners were presented with vibrotactile stimuli via a chair's surfaces (left and right arm rests, back rest, seat) in addition to music presented over headphones. Vibrations for each surface were derived from individual tracks of the music (multi condition) or conjointly by a mono-rendering, in addition to incongruent and headphones-only conditions. Listeners evaluated unknown music from popular genres according to valence, arousal, groove, the feeling of being part of a live performance, the feeling of being part of the music, and liking. Results indicated that the multi- and mono vibration conditions robustly enhanced the nature of the musical experience compared to listening via headphones alone. Vibrotactile enhancement was strong in the latent dimension of 'musical engagement', encompassing the sense of being a part of the music, arousal, and groove. These findings highlight the potential of vibrotactile cues for creating intensive musical experiences.
声音可以通过耳朵感知，也可以通过皮肤感知，即通过振动触觉刺激来感知。只有很少的研究涉及到音乐领域中振动触觉刺激的感知含义。在这里，我们研究了音乐聆听的哪些感知维度受到振动触觉刺激的影响，以及振动的空间分离是否能改善振动触觉刺激。41 名听众在耳机播放音乐的同时，还通过椅子的表面（左右扶手、靠背、座位）接受振动触觉刺激。每个表面的振动都来自音乐的个别曲目（多条件）或通过单渲染共同产生，除了不一致和仅耳机条件。听众根据愉悦、唤醒、律动、现场表演参与感、音乐参与感和喜好来评价流行音乐流派的未知音乐。结果表明，与仅通过耳机聆听相比，多振动和单振动条件有力地增强了音乐体验的本质。振动触觉增强在“音乐参与”的潜在维度中很强烈，包括作为音乐一部分的感觉、唤醒和律动。这些发现突出了振动触觉提示在创造强烈音乐体验方面的潜力。
