Objective. To test the hypothesis that listening to the music with the effect of binaural beats of theta and delta range during nap decreases sleep latency defined by 2nd slow wave sleep stage appearance, as well as improves its stability. Material and methods. The experimental set of 20 min duration was established according to the counterbalanced scheme with 21 subjects. Each subject participated in two attempts: one attempt included sound stimulation (music) and another one was sham (silence).Results and conclusion. The decrease in sleep latency during stimulation is not confirmed reliably. The increase in sleep stability has been confirmed reliably using nonlinear regression model. The findings can be used in the development of non-pharmacologic ways of sleep treatment. © 2020, Media Sphera Publishing Group. All rights reserved.
