| Abstrakt: | Objective: The aim of this study was to test on a large group of subjects the hypothesis that sleep latency (SL) does not depend on the nature of low-frequency beats embedded into monotonous sound stimulus supplied through the fall-asleep process. Specifically, it does not depend on whether those beats are monaural (MB) or binaural (BB). Material and Methods: A special application for Android OS was developed and installed on the individual smartphones of 221 subjects for the purpose of the study. Three attempts were performed with each of them using 3 different kinds of monotonous sound supplied according to counterbalanced design. Three kinds of sound were identical in pitch but differed in the beat presence and type: BB, MB or sham (sound without beats). Results: Repeated measures analysis of variance (rANOVA) revealed no significant statistical effect of stimulus type on SL ( p =0.21). A pairwise comparison of SL for different stimulation conditions showed the null hypothesis significance level adjusted according to multiple comparison correction to be p =1.0. Thus, in this experiment SL did not significantly depend on the monotonous sound stimulus type: MB, BB, or sham. Conclusion: The software application developed is useful as universal platform to assess at home conditions the impact of various external factors on fall-asleep process. |
