Although binaural beat therapy (BBT) has been demonstrated to alleviate symptoms of anxiety and depression, but the effects of BBT of different frequencies on college students have not been thoroughly explored. This study explored the effects of BBT with different frequencies on autonomic nervous system regulation (i.e., anxiety reduction) among college students.
This was a quasiexperimental study. Participants were recruited from a university in southern Taiwan. Each of the participants received interventions with different frequencies (theta frequency, 6 Hz; alpha frequency, 10 Hz; and beta frequency, 25 Hz). For each intervention, participants were subjected to 20 min of natural sounds embedded with binaural beats of a specific frequency. A pretest and posttest were conducted to measure blood pressure (BP) and heart rate variability.
A total of 65 participants were recruited. The mean age of participants was 20.15 years. Heart rate and systolic and diastolic BP were significantly lower after intervention with theta-frequency binaural beats (p < 0.05). Systolic BP was significantly lower after intervention with alpha-frequency binaural beats (p < 0.05). Heart rate, systolic BP, and nLF were significantly lower and nHF was significantly higher after intervention with beta-frequency binaural beats (p < 0.01). No significant differences were observed between the effects of the three interventions on ANS regulation among the participants.
BBT, in which participants were subjected to theta-frequency, alpha-frequency, and beta-frequency binaural beats for 20 min, contributed to reducing anxiety. No significant differences were observed between the effects of each frequency.
尽管双耳节拍疗法（BBT）已被证明可缓解焦虑和抑郁症状，但不同频率的BBT对大学生的影响尚未得到充分研究。本研究探讨了不同频率的BBT对大学生自主神经系统调节（即减轻焦虑）的影响。
这是一项准实验研究。参与者从台湾南部的一所大学招募。每位参与者接受不同频率（θ波频率，6赫兹；α波频率，10赫兹；β波频率，25赫兹）的干预。每次干预时，参与者聆听嵌入特定频率双耳节拍的自然声音20分钟。进行了前测和后测以测量血压（BP）和心率变异性。
共招募了65名参与者。参与者的平均年龄为20.15岁。使用θ波频率双耳节拍干预后，心率以及收缩压和舒张压显著降低（p<0.05）。使用α波频率双耳节拍干预后，收缩压显著降低（p<0.05）。使用β波频率双耳节拍干预后，心率、收缩压和低频功率显著降低，高频功率显著升高（p<0.01）。三种干预对参与者自主神经系统调节的影响之间未观察到显著差异。
让参与者接受20分钟的θ波频率、α波频率和β波频率双耳节拍的BBT有助于减轻焦虑。各频率的效果之间未观察到显著差异。
