Acoustic stimulation is clinically relevant for the reduction of insomnia, according to a clinical trial at Wake Forest Baptist Health.

Individuals (N=107) with clinical diagnoses for insomnia without secondary causes were recruited for this study. In addition to current care, participants were randomized in a 1:1 ratio to receive tones linked to brainwaves (LB; n=56) or tones not linked to brainwaves (NL; n=51) during 10 sessions over 3 weeks. Participants had a brainwave assessment within 7 days of the study conclusion and were asked to respond to an Insomnia Severity Index (ISI) questionnaire at each visit.
