Abstract

Music with embedded binaural beats (BBs) is a promising noninvasive tool for insomnia treatment. This work tests the hypothesis of “entrainment” effect of that kind of music on human brainwaves as a physiological mechanism of sleep improvement. The spectrum of auditory steady state response has been compared in the group of 21 subjects during daytime sleep onset, with music embedded with BBs of 2 and 4 Hz (stimulus condition) and without any stimulus (control condition). Significant difference in auditory steady state response power has been found between conditions at 14 Hz (“sleep spindle” frequency). However, no significant difference has been found at frequencies of 2 and 4 Hz embedded to add a somnogenic feature to the music stimulus according to the hypothesis tested. The results obtained do not support the hypothesis of “entrainment” effect of the stimulus examined on sleep; yet they support the conclusion made in the previous authors’ paper that it improves daytime sleep quality.

白天睡眠时对嵌入双耳节拍音乐的听觉稳态响应

摘要

带有嵌入式双耳节拍 (BBs) 的音乐是一种很有前途的失眠治疗非侵入性工具。这项工作测试了这种音乐对人类脑电波的“夹带”效应作为睡眠改善的生理机制的假设。已经在白天睡眠开始时比较了 21 名受试者的听觉稳态反应谱，音乐嵌入了 2 和 4 Hz 的 BB（刺激条件），没有任何刺激（控制条件）。已发现在 14 Hz（“睡眠主轴”频率）的条件下，听觉稳态响应能力存在显着差异。然而，根据所测试的假设，在嵌入 2 Hz 和 4 Hz 频率以向音乐刺激添加催眠特征时没有发现显着差异。获得的结果不支持所检查的刺激对睡眠的“夹带”效应的假设；然而，他们支持之前作者论文中得出的结论，即它可以改善白天的睡眠质量。
