The Effect of Polyphonic Lullaby and Pish Pish Sound on Sleep Transition and Sleep Duration in Newborns

After discharge, mothers will be asked to play the Dandini Dandini Dastana lullaby by vocal artist Mircan Kaya, which they downloaded from the YouTube application, and listen to it from a distance of one meter (away from the baby's head to minimize radioactive effects) and by switching the phone to airplane mode just before sleep. In the event of active sleep (signs of sleep transition such as slowing down muscle movements and closing eyes), the polyphonic lullaby volume will be gradually reduced. The polyphonic lullaby will be played at a volume level of 55 decibels for the first 5 minutes after falling asleep, then reduced to 25 decibels and then turned off. In order to reduce the effects of confounding factors, mothers in the polyphonic lullaby group who use another assistive method (breastfeeding/rocking to sleep) to put their babies to sleep will be excluded from the study.

After discharge, mothers will be asked to turn on the Piş Piş sound downloaded from the YouTube application and listen to it from a distance of one meter (away from the baby's head to minimize radioactive effects) and by turning the phone to airplane mode just before sleep. In case of active sleep (signs of sleep transition such as slowing down muscle movements and closing eyes), the piş piş sound will be gradually reduced. The polyphonic lullaby played will be at a volume level of 55 decibels for the first 5 minutes after falling asleep, then reduced to 25 decibels and then turned off. In order to reduce the effect of confounding factors, mothers in the piş piş sound group who use another assistive method (breastfeeding/rocking to sleep) to put their babies to sleep will be excluded from the scope of the research.
