A case of musicogenic epilepsy is reported in which the seizures were precipitated by singing voices. It was found that some singers' voices were particularly epileptogenic and that some of their songs, but not others, would precipitate a seizure. A study of the "offending" songs and singers did not reveal a common key, chord, harmonic interval, pitch or rhythm, and the emotional feeling or intensity of the music did not seem to be relevant. However, the voices that caused the seizures had a throaty, "metallic" quality. Such a singing voice results from incorrect positioning of the larynx such that it is not allowed to descend fully during singing; consequently, the vowel sounds produced must be manipulated by the lips or jaw to be distinguished. This trait is most common in singers with a low voice range who sing softly and use a microphone. It is not seen in trained operatic or musical theatre singers. The results of repeated testing showed that the seizures in this patient were caused by listening to singers who positioned the larynx incorrectly.
报告了一例音乐源性癫痫病例，其发作由歌声诱发。发现一些歌手的声音具有特别的致癫痫性，且他们的某些歌曲（而非其他歌曲）会诱发发作。对“致病”歌曲和歌手的研究未发现共同的调式、和弦、和声音程、音高或节奏，并且音乐的情感感受或强度似乎也无关紧要。然而，引发发作的声音具有沙哑的“金属”质感。这种歌声是由于喉部位置不正确导致在唱歌时不能完全下降而产生的；因此，发出的元音必须通过嘴唇或下巴来调整才能区分。这种特征在音域较低、轻声唱歌且使用麦克风的歌手中最为常见。在训练有素的歌剧或音乐剧歌手中则未观察到这种情况。反复测试的结果表明，该患者的发作是由聆听喉部位置不正确的歌手演唱所致。
