“We tested whether non-auditory low-frequency stimulation would increase audience dancing by turning very-low frequency (VLF) speakers on and off during a live electronic music concert and measuring audience members’ movements using motion-capture. Movement increased when VLFs were present, and because the VLFs were below or near auditory thresholds (and a subsequent experiment suggested they were undetectable), we believe this represents an unconscious effect on behaviour, possibly via vestibular and/or tactile processing.
People attending a performance by the electronic music duo Orphx at the LIVELab were recruited for the study. Participants gave informed consent, were fitted with motion-capture marker headbands, and completed pre- and post-concert questionnaires (see Supplemental information). We turned VLF speakers (8–37 Hz) on and off every 2.5 minutes over 55 minutes of the performance (Figure 1D), calculated head movement speed (the three-dimensional path length per sampling unit of time) for each participant in each of the eighteen segments, and compared average normalized movement while VLFs were ON vs. OFF. Our data show that audience participants moved more, on average by 11.8%, while VLFs were ON vs. OFF (t(42) = 5.32, p < 0.0001; d = 0.81; Figure 1E).”
