Treating Major Depressive Disorder With Music and Low-frequency Rhythmic Sensory Stimulation

"The stimulation consists of 30 minutes of daily stimulation with specially composed relaxing music tracks embedded with gamma frequency sounds of 30-70 Hz range.~In this study, the stimuli will be delivered with a portable sound device called Sound Oasis Vibroacoustic Therapy System (VTS-1000) unit, which is a low-voltage consumer product that has two built in mid to high frequency speakers and one built in low frequency (subwoofer-type) speaker. The low frequency sounds played by the subwoofer speaker is experienced as vibrotactile vibration. Although the Intervention of Interest in this study is the Rhythmic Sensory Stimulation with low-frequency sounds, the efficacy of the Sound Oasis VTS-1000 device to deliver the intervention will also be subject to observation."
