Getting enough sleep is linked to several important aspects of human existence, such as
preserving health and achieving better results at work. Sleep disturbance can result in
several physiological and psychological problems. There are many factors affecting sleep
quality including sleep habits, exercise, stress and anxiety, sleep disorders, light intensity,
temperature and environmental noise. The primary goal of the study was to determine if
continuous rhythmic white noise in combination with 3Hz binaural beats might be used
as a non-pharmacological therapy for improved sleep quality, sleep fragmentation,
latency, and relevant sleep parameters. The impact of continuous rhythmic white noise on
sleep parameters was assessed using both hardware and questionnaire methods. Data
from thirty subjects (16 females, mean age, 24.9±1.08 years), was collected using a
variety of questionnaires, including the Pittsburgh Sleep Quality Index, reduced
Morningness-Eveningness Questionnaire, Adolescent/Adult Sensory Profile, St. Mary
Hospital Sleep Questionnaire, and a wearable sleep tracking device, Fitbit Charge 4. The
questionnaire-based data was evaluated using chi mean square and the hardware-based
data was analyzed using ANOVA and post hoc analysis where applicable. The results
show that continuous rhythmic white noise combined with binaural beats has a significant
impact on sleep quality, sleep score, total sleep duration, deep sleep duration and REM
duration (p-value<0.05). The continuous rhythmic white noise in combination with
binaural beats can be used to enhance specific aspects of sleep, particularly REM sleep,
which is critical for cognitive and emotional well-being. In conclusion, this study
demonstrated the potential of continuous rhythmic white noise in combination with 3 Hz
binaural beats for improving the sleep quality of the individuals in noisy settings.
